Miocene_Mason Posted June 24, 2018 Share Posted June 24, 2018 Went for my first time to purse state park proper (Douglas point is my usual Potomac haunt). Mostly for micro, but I did a bit of surface hunting. Found this beautiful vert, find of the day by far (disappointing otherwise). I’ve no clue what it is, though I assume some sort of gharial. My quick research brought me to eosuchus being the best candidate. With a surprising resemblance to champsosaurus but I think that’s unlikely. Any ideas? Gonna go ahead and tag @MarcoSr. Thanks! “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Troodon Posted June 24, 2018 Share Posted June 24, 2018 It does looks like a Croc vert. Quite a few described from the Aquia not sure the centrum will give you an ID but lets see what others say. Not Champsosaurus 2 Link to comment Share on other sites More sharing options...

I was hoping there would some diagnosistic feature but perhaps not. I looked at a drawing of a thecacampsia vert, looked different but perhaps it’s just because mine is caudal (I think). “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

jpc Posted June 24, 2018 Share Posted June 24, 2018 Definitely crocodilian vertebra. I don't see any chevron attachment points so it may not be caudal, but the chevron spots may be worn away. 1 Link to comment Share on other sites More sharing options...

Miocene_Mason Posted June 24, 2018 Author Share Posted June 24, 2018 Also, does anyone know about what level of rarity here? I’ve never seen another one of these, but I have a feeling that if I found it in twenty minutes it’s probably not the rarest thing.. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

This is true, typically my luck is not amazing (save the singular Symphyseal cow shark tooth). However, I’m a firm believer that luck can change! Is this like Otodus rare, aksauticus rare, or Striatolamia rare? Perhaps in between one of those? “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Can't really say more than that about the id. I've hunted the Palaeocene Aquia Formation for over forty years and only have 4 or 5 croc vertebrae from it. I've seen more skull and jaw pieces than vertebrae so a vertebra is pretty uncommon based upon my experience.

I've seen crocodilian vertebrae from Miocene sites that break that way too. It seems like a natural plane of separation because the break tends to look clean if there is less than moderate weathering. I have one from a Florida site like that.

Cetecean verts do the same thing. Ive got some fossil alligator vertebrae, ones got it, one doesn’t, and one has part of it.

jpc Posted June 25, 2018 Share Posted June 25, 2018 missing neural arches is normal for fossilized croc verts, form my experience. Jurassic, Cretaceous, Paleocene, Eocene of Wyoming and surrounding states. A complete croc vert is a great find around here. 1 Link to comment Share on other sites More sharing options...

I wonder why the vertebrae would be rare, a lot more of them than skulls! I’m quite happy about finding one though! I read that one paper, but it was a while ago. It’s very nice and informative. I’ve just sent a membership form to the Maryland Geological Society, figured it is he logical next step for my fossil-hunting. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
