Emerald Isle, NC

Last weekend we had a short but nice going away get-away with some friends (psychology graduate students, a parole officer, and a lawyer/rockstar) in Emerald Isle, North Carolina.

My dorky goal was to find more fossilized shark teeth (see previous awesome finds here), in addition to the obvious general goal of having a salty time.

Unfortunately, a storm kept most of the cool ocean debris from washing ashore until Sunday morning. Nevertheless, I found quite a few interesting things.

First off: fossil shark teeth!

A cool fossil of what I think is a bryozoan.

I found a nice piece of fossilized bone. Of what? Who knows? Probably whale or dolphin. Or perhaps mermaid.

I also found several chunks of what I believe is either anthracite coal, or the next metamorphic step - graphite (I'm no geologist - thoughts?). It's very light weight, very hard, and very faceted - which doesn't come across very well in still shots:

Anthracite Coal?

One of the coolest things I found is a relation to organisms I will soon be working with in my new lab: starfish!!
I found two of these, both beautifully colored and still alive. They were washed ashore by the storm, so I tossed em back. I have no idea the likelihood of their survival, but I can say they didn't wash back ashore over the next two days. (I'm awaiting the expertise of Christopher Mah of the Echinoblog for species identification).
Update: it's a Royal Sea Star, Astropecten articulatus. Quoth the EchinoMaster: "Basically..they are your stereotypical "sand star" predatory on infaunal bivalves and pretty common on sandy-muddy bottoms of the Northeast US.  Attractively colored animals to be sure!" Thanks Chris!

Starfish

Check out those details!

Tube Feet Alive!!

We also got to hit the NC Aquarium in Pine Knoll Shores. It's a pretty rad place, so I was way more interested in pointing my eyes at all the ocean wonders, rather than pointing a camera. But I did get this cool shot of a gator.

Gator

Ooh - and apparently someone else took a shot of us there - me and John playing with the rays (the ray touch tank was by far the coolest part!).

Topsail Island, NC

A month ago, we also had the opportunity to hit Topsail Island, NC.

Fun was had. Things were seen.

Shark Teeth (Yes - I showed these before).

Great colors!

Ocean smoothed - but still pretty wicked

And that's it - images are all I have for you at the moment. Enjoy.

I swear, I will have slightly more posts once I get moved to Pittsburgh and settled.

And just because I never show her (she's camera shy), I'm sneaking in this shot of my wife:

Three Psychologists

Mind you, since moving here for graduate school, fossil hunting had fallen off of my priority list, largely owing to the fact that central Carolina rocks are basically all metamorphic (melted and recrystallized by heat and pressure). And I've never been the gung-ho research-fossil-sites-and-go-hunting type. Since I began collecting while living in the Ozark mountains, it was more of a walk-through-my-parents-woods-and-see-what-fossils-I-find-today sort of hobby, with a few far-flung excursions in the mix.

Well that all changed a few weeks ago. My wife, some friends, and I spent a couple of days at Topsail Beach, NC.

Actually - scratch that - it began a few month's ago, when Christie at Observations of a Nerd reported an awesome find of fossil shark teeth in Florida, and then - like the wonderful person she is - sent me a handful of them.

Shark Teeth from the wonderful Christie (Note to Christie - they are ray dental plates - not stingray barbs - just learned that - see below)

Back to Topsail Beach, circa a few weeks ago.

I said to myself, "Self - it's the ocean - there are bound to be fossil shark teeth. You (I) will not allow me (myself) to leave this beach without finding at least one shark tooth."

So I spent all my beach time on Saturday perusing the sands for teeth.

To no avail whatsoever. I never saw one.

The next day, I began again, searching much more intently. While combing the fresh tide-swept beach, I saw a tiny black triangle amidst the shells. It was a shark's tooth!!

The filters through which my perception is sifted were now calibrated. Within the next few hours I had a nice handful of tiny teeth. I was ecstatic.

(Note for the fossil pros and beach inhabitants out there: feel free to laugh at my ignorance of what constitutes awesome shark teeth. But these were just about the coolest things I had ever found - at the time.)

Hold your applause - you ain't seen nothing yet

Tiger Sharks - grrrr...er...meow

Thus was I hooked on shark teeth.

The next necessary stops in my tale are the mountains of West Virginia and hills of Pennsylvania.

Some of you know that I will recently begin a new job at Carnegie Mellon University. As such, we have driven there twice recently. I am utterly awed by the massive amount of roadcuts through the mountains of the two states, all of which reveal millions upon millions of years of Earth's natural history in it's geological strata. I felt the fossil-hunting bug really kick up several notches while driving through those strata.

Thus, in anticipation of my move, I began hunting online for potential fossil sites in Pennsylvania. In this endeavor I discovered The Fossil Forum. Through this forum, I discovered not only a huge community of avid fossil hunters, experts, and enthusiasts, but also that North Carolina has some of the most amazing shark tooth sites in the country.

"Self," says I, "it's bad enough that you've been here so long without discovering North Carolina's fossil sites - but now you are leaving? I forbid you (myself) from leaving until you have visited these sites. Got it?"

It was decided - the July fourth weekend was my only free one from now until the move, thus I would make it a fossil-hunting weekend. I would spend Friday in Aurora, NC and Saturday at Green's Mill Run, a creek in Greenville, NC.

As fate would have it (though we will soon see that the result would have been the same with any weekend, fate or no) a dude by the name of MikeDOTB (Michael Taggert) on the Fossil Forum, was also making the exact same trip this weekend. We decided to meet at the shark-digging piles at the Aurora Fossil Museum on Friday (Note to parents in NC - TAKE YOUR KIDS HERE! Free digging teeth by the thousands to their little hearts' content). Mike said he would be there by 7AM and I would try to get there by 9AM (it's a 3.5 hour drive for me).

NOTE: See Mike's Trip Report here - he has some amazing shark teeth!

I was too excited. I couldn't sleep at all the night before. So I slid out of bed and out the door at 3AM arriving at the piles in Aurora by 6:30AM. (The piles are Pungo River Formation sediment - age ~18-22 million years -  donated by the nearby PCS phosphate mine).

It was just me. Not a soul in sight anywhere. Alone - in a beautiful dawn with giant piles of Miocene sediment to sift through at my leisure.

I saw my first tooth within about ten seconds of glancing at the piles. My collection grew fast and linearly from that point onward. Before too very long, a nice man showed up to sift as well. It turned out that he was a Fossil Forum member too (runner50) - a Kansas Science teacher on a trip around the country to spread his recently deceased wife's ashes at their favorite locations (including St. Claire, Pennsylvania which has some amazing fern fossils, which he showed me). Many of the ancient teeth he was collecting were for his students/class. Despite the sadness of his tale, it was incredibly heartening to meet such a man teaching in Kansas, a place we all probably know needs good science teachers!

In "the wild"

Mike showed up later than he had planned, but as soon as he got there we hit another nearby pile, meeting a guy named Brian in the process. We chatted for quite a few hours as the three of us sifted for teeth in a couple different locations. Brian, another Fossil Forum member, gave me a dolphin vertebra among other things.

Dolphin Vertebra - Thanks Brian!!

Fossil enthusiasts are awesome people, based on the few I've met!

Mike, Brian, and Me - sifting the piles in Aurora, NC

The piles

I almost look like a real paleontologist. Or not...

Before the day was up I had amassed a huge pile of little shark teeth, though no lunkers had given themselves up. I had already watched in envy as Mike pulled several beautiful teeth from the piles. However, I wasn't really jealous, as I was too excited from the insane numbers of teeth I  was finding with my smaller 1/4" mesh screen. After about 13 hours straight (no lunch break or anything), darkness began to loom. So Mike decided to collapse the pile we had been digging into. Wet internal sediment began falling and we both began picking through it as more fell. In about a third of a second a shiny glint caught my eye in the muddy dirt. I snapped at it like a greedy hungry chicken.

It was a big Extinct Giant Mako (Isurus hastalis)!

Extinct Giant Mako make-o me happy

Also, it had a small bit of feeding damage at the very tip (which makes it only cooler to me). Now go back and compare that to my first teeth from Topsail...

Without further ado, I give you the rest of my collection from Friday, filled with makos, tigers, sand tigers, snaggletooths, cow sharks, and even one small  nearly complete tooth and some pieces of megatoothed sharks (C. megalodon and/or chubitensis).

Note: I have zero tooth ID skills, so forgive any errors. There are almost certainly teeth "out of place"! I arranged these pretty quickly.

The Multi-Million Year Old Catch

Aren't they pretty?

A few of these were given to me by Mike - I don't remember which ones. Thanks Mike! He also gave me the coolest thing I now own...keep reading.

Snaggletooths and Tigers

Sand Tigers et al

Megalodon/Chubitensis?

Makos, giant megalodon chunk, and others...

Requiems, Coppers, Hammerheads? No idea...

Broken cow sharks

Ray dental plates (for grinding munchies)

The little guys (Mike estimated ~1200 total teeth)

Did you know a single shark can go through 30,000 teeth in a lifetime?

And of course, I found some other cool stuff as well...

Shark Vertebrae

How cool is that?

Coral

Love the detail in these things!

So I had a great haul - and searing back and arms as payment to Mother Nature for her bounty. But back pain or no, we had another whole day to go.

Mike and I high-tailed it to Greenville and crashed at the Motel 6, after spending at least an hour rinsing and gawking at our fossils. Mike gave me most of his teeth, except for the near perfect ones he deemed fitting for his collection. What an awesome dude!

Then again, this is a guy who has 30,000 teeth! Also, he seemed to know every single shark species, their scientific names, whom is thought to have begat whom evolutionarily, and he could instantly tell the ID of each tooth. Oh yeah, and remember how I said "Fate" had led me to want this trip at the exact same time that Mike announced that he was planning a trip? Yeah, well, he has gone on this trip almost every weekend since January.

Yeah - he's an enthusiast alright... Thanks Mike - you rock!

We awoke the next morning and headed for the dirty, trash-filled, broken glass-laden creek running near East Carolina University campus known as "Green's Mill Run." This place is famous for yielding big megalodons and great whites (and ancient soft drink bottles and bongs). The creek cuts through layers from the cretaceous to the pliocene, so things found in it can range from about 2.5 to 145 million years old!

The story was much the same at "GMR". I found quite a few great teeth (though I didn't feel as inclined to pick up every tiny tooth after the previous day), including another awesome Mako.

This was while I was still clean...

Mike found an AMAZING great white, and lot's of other great teeth - many of which he gave to me.

Mike's Great Whites

I sat and watched an awesome freshwater eel hunting minnows in one beautifully sunny pool - a first for me. We didn't have freshwater eels in NW Arkansas (that I'm aware of).

Mike found and gave me what I easily consider the coolest fossil I now own (he already has several): the fossilized inner ear bone of a whale. What kind? not a clue.

Whale's inner earbone

We visited one particular spot in the creek that cuts through this crazy shell layer filled with huge scallops and various mollusks.

Fossil Sea Scallop (as opposed to land scallop)

Some sort of big bivalve - whole and heavy!

By 6PM my back and arms would not let me sift a single more shovel load. Thus we called it a day.

Here's the total haul from Saturday:

The GMR Catch

What would have been HUGE megalodons, a very nice Mako, and a rootless great white

The Makos and the White

The other shark teeth

Another cool fossil that exists by the millions in GMR is the belemnite. Belemnites were cephalopods related to modern cuttlefish. Only one part of it's body is normally fossilized: a calcite rod in it's body that assists in maintaining proper buoyancy. These things are just cool looking - orange and long and pointy, with a translucent character in the water.

Fossilized Belemnite guards (or rostrum)

And finally, the creek has quite a lot of pieces of whalebone:

Fossilized whale bone (and a cretaceous oyster - according to Mike)

All in all, this was by far the coolest natural history excursion I've been on (or perhaps second best behind a trip to Big Bend where I found an ammonite 4 feet in diameter - I left it there).  If you read this far - I hope you enjoyed my tale. If you didn't...well... you can't see this anyway.

The total weekend haul!

Cat included for scale

Next up: fossil hunting in Pennsylvania in the next month or two! When exactly or where I don't know. But it will be fun!

nope - not a fake at all...

I hang out online sometimes with a bunch of like-minded fossil-enthusiasts (The Fossil Forum).

Tonight somebody posted this:

Just watched the new this evening and they were talking about a dig going on right now outside of Glen Rose, on the McFall ranch. The news showed the footprints of the therapod and the human prints together. It was interesting. For report go to cbs11tv.com

So I mosied over to the Dallas, TX CBS news site and found the article "Local City Known As Dinosaur Capital Of Texas, by Arezow Doost."

Sounds innocuous enough for a title, right?  Then I read the first three sentences:

"Did you ever think that there were dinosaurs in North Texas?

As it turns out, this is one of the most prolific areas for dinosaur tracks in the state. One group of scientists have even found tracks dating back millions of years."

Read that last sentence again:

"One group of scientists have even found tracks dating back millions of years."

Cause, you know, all those other groups found tracks that weren't millions of years old...
(for those of you who missed out on elementary school, dinosaurs went extinct at the end of the Cretaceous sixty-five million years ago.)

Absolutely hilarious...and mind-numbingly maddening.

After reading a bit more, then you learn what it is really about:

"Scientists believe that one of the most unique findings is human prints dating back to the same period as the dinosaur prints. "We are looking for the truth," said Baugh. "We don't want anything else but the truth.""

I rolled my eyes. Obviously, I had a feeling what I would find out with a little search, but I decided to check out the scientist quoted in the piece, because I thought it was a bit odd that he said "We are looking for the truth. We don't want anything else but the truth."

You see, that is a very non-scientist thing to say in a media piece, and it instantly threw up a red flag to me. I say this because when one is actually in the practice of being a good scientist, a statement like that is like a commercial fisherman saying "no really, we're just out here to catch fish." What else would a fisherman be fishing in the ocean for? If you're a scientist, a statement like that is less than unnecessary.

Yeah this guy, Carl Baugh, is a young earth creationist discredited in the scientific community and with a questionable education. He is obviously seeking to prove his own wrong beliefs - not actually do what good scientists do, which is let the data speak for themselves. Check this out for some rather hilarious reading on Baugh: http://en.wikipedia.org/wiki/Carl_Baugh

Sigh...it is Texas after all (I was born and raised in east Texas, FYI)

As an added moronic bonus, if you look at the url of the story you'll see that it's filed under "pets."
(http://cbs11tv.com/pets/Texas.Dinosaur.Capital.2.1069336.html).

What kind of of idiots are running that station?

One thing about the fossil record - it's insanely consistent across both time and continental space, if fragmentary. And it has consistently shown us that human and therapod existence is quite a few tens of millions of years apart.

Hell, mammals were barely existent back then, compared to today. But primates? LOL - no.

***

Side note: I'm going fossil hunting in Aurora, NC tomorrow and at Greens Mill Run in Greenville, NC on Saturday!!  Shark teeth here I come. Please just let me find a megalodon.

Ever since I was a small child I have been collecting fossils.  In fact, I can trace my own fascination with biology directly to my discovery that the very house in which I lived (actually a trailer back then), was set upon land literally made of these long dead and formerly ocean-dwelling ancestors and distant cousins. I'll never forget the awe that crept into my little brain as I tried to imagine enormous oceans covering my forested Ozark mountains.

When I was very young, my Mamaw (paternal grandmother) gave me a simple large toolbox for Christmas - a toolbox with a myriad little compartments intended for the sole purpose of housing my growing "rock collection."

For years I filled this box and a couple more with fossils, rocks, gems, shed snake skins, feathers, arrowheads, seashells, and all manner of relatively non-decomposable animal and plant remains - almost all of which I found myself.

The time came when I was not content to let my collection sit in toolboxes in a closet. Thus I built a shadowbox coffee table during graduate school (with super thick glass so my cats could leap onto it from 10 feet away without smashing my fossils...er...the glass and themselves). Now my collection fills my coffee table and almost every bookshelf in my home.

Coffee Table Fossils (& other stuff - click for larger)

I've amassed a decent collection - I'm proud of it anyway, though any paleontologist or geologist would almost certainly laugh at it. Most of them are simple ocean invertebrates, as most of them came from Carboniferous Period limestone of the Ozark Mountains (the entire region is pretty much made of pure crinoids).

All of the above being said, I'm a bit ashamed to admit that I don't know that much about many of my fossils.

Thus, I am starting this series of posts to catalog my entire collection and to see what the experts out there can teach me and all of us about some of our long lost branches of life. Please, if you can add any information whatsoever, it would be much appreciated - i.e. taxonomy, factoids, comments, conjecture, anything. And please point out if I have identified anything incorrectly - a very real possibility.

For this first installment, I am going to begin with my most recent additions - all found this weekend in Bella Vista, Arkansas where I returned for my mom's wedding.

A hat tip goes out to my four nieces (ages 9 to 12) for helping me find them.

Location: Bella Vista, Benton County, Arkansas

Fossils

What I know: based on my limited understanding of the region's geology, these rocks are primarily limestone from the carboniferous period (and I believe they are towards the boundary between Pennsylvanian and Mississippian - but I could easily be wrong. I know very very little about geology).

Note: You can click on all images for higher res/quality images. These are highly compressed for bandwidth. I've tried to give multiple views of each fossil.

#1 - Crinoid

#2 - Productid Brachiopod - Order Strophomenida

Update: information provided by Chris Nedin, of Ediacaran: "looks like a productid brachiopod. Order Strophomenida, Suborder Productidina. They can be distinguished by being large, very rounded, with a thick, heavy shell, and along the top, a very straight hinge line, with almost nothing appearing above the hinge line. An example is here at image 408."

#3 - Spirifid Brachiopod - Order Spiriferida

Update: information provided by Chris Nedin, of Ediacaran: "an internal mold of a spirifid brachiopod, Spiriferida, Suborder Spirifieridina. The shell has been filled with sediment and that has hardened. Then the original shell has dissolved away, leaving the sediment inside, which is what you see. The shape is caused because the shell tapers down to a point away from the centre, and curls somewhat. An example is here."

I know - these aren't exactly impressive specimens. However, I already had them unpacked and laid out so I figured I'd start with these. I definitely have some other cool ones to come in future posts.

If you know of any fossil aficionados, please send them this way, as I would really like to know at least a little bit more about my collection. If any of you end up being particular helpful, I may just send you one of my awesome limestone rocks made of pure crinoid discs (they're much cooler than those above), assuming you don't already have some or consider them too bland
