Lone Hunter Posted April 10, 2022 Share Posted April 10, 2022 A bit of a vertebra theme tonight so thought I'd jump in, found this in creek in Cretaceous Eagle Ford but the area is QT and QAL also. It's not fully mineralized just like most bones from around here, I think it looks like croc but it's very worn so could be wrong. Link to comment Share on other sites More sharing options...

JohnJ Posted April 12, 2022 Share Posted April 12, 2022 Try a few more photos from right angles. These oblique views are not as useful. 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

JohnJ Posted April 12, 2022 Share Posted April 12, 2022 These are still oblique views. They become more meaningful if they are associated with more standard views like these: The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Jared C Posted April 12, 2022 Share Posted April 12, 2022 Do you think it's cretaceous? Usually the pores on cretaceous bone are "filled in", at least in my experience. 1 1 “Not only is the universe stranger than we think, it is stranger than we can think” -Werner Heisenberg Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted April 12, 2022 Share Posted April 12, 2022 I agree that this looks crocodilian to me, but I'm far from versed in their vertebral material... Doesn't look like mosasaur, in any case, and it's not "square" enough looking for horse, in my opinion. 1 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
JohnJ Posted April 12, 2022 Share Posted April 12, 2022 It has all the characteristics of an eroded mammal vertebra. 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

Though I thought the vascularisation in crocodilian bone is also quite high, isn't it? At least in examples I've seen, like this one... Although, it would make sense for crocodile bone to be denser than terrestrial mammal bone, as crocodiles need to overcome the problem of neural buoyancy, of course. 2 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
caterpillar Posted April 12, 2022 Share Posted April 12, 2022 I think it's a croc vertebra. The centrum is more circular than mammal vertebra 2 http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
Lone Hunter Posted April 12, 2022 Author Share Posted April 12, 2022 I thought I covered every angle, I would think it's Pleistocene rather than Cretaceous. 1 Link to comment Share on other sites More sharing options...

I suspect it is from a cleaner gravel deposit, or has been rinsing longer. It is distinct from the mammal and bird bones I have found for some reason.

JohnJ Posted April 12, 2022 Share Posted April 12, 2022 8 hours ago, Lone Hunter said: I thought I covered every angle, I was hoping for right angles to the basic form like these. This horse thoracic vertebrae has a 1.5 inch 'diameter' posterior centrum and an overall 4.75 inch width. Also of note are the foramina within the neural canal and the side of the centrum. @Lone Hunter's vertebra has a comparable morphology and details. Her find has been broken and heavily eroded. One could imagine my piece looking similar if undergoing the same environmental abuse.

Lone Hunter Posted April 12, 2022 Author Share Posted April 12, 2022 For what it's worth here's a few more shots. I had a sneaky feeling you would say it's horse, isn't this a little too small though? 1 Link to comment Share on other sites More sharing options...
