garyc Posted November 8, 2019 Share Posted November 8, 2019 I found this bone years ago on the Brazos River and never got around to asking for help with an I’d. Could this be from a bird? It seems hollow, but well mineralized. Link to comment Share on other sites More sharing options...

Auspex Posted November 8, 2019 Share Posted November 8, 2019 I think the walls are way too thick for it to be avian. Neither do the remaining morphological details match up with any part of a bird's skeleton. Mammal, me thinks. 2 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

Harry Pristis Posted November 8, 2019 Share Posted November 8, 2019 My own impression is that of a proximal bird humerus, but I'm not a bird expert. I can't think of a mammal or reptile with such a pneumatic structure. http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

The tendon foramen centered under the 'head' is not an avian feature, at least not that I have ever seen. I wonder whether the partially pneumaticized structure is a sea turtle adaptation? 1 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

I confess that I searched images of bird humeri for such a foramen -- without finding one. 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Shellseeker Posted November 8, 2019 Share Posted November 8, 2019 So, Time to re_access I am beginning to believe this is something else. Two experienced fossil experts who know as much as anyone on bird, turtle bones are having trouble Identifying. I am concerned about the lack of "curvature" on this bone compared to turtle. I was hunting this week and tossed a bone from a large mammal (Equus ??) that was hollow all the way thru... How did it get that way? PrehistoricFlorida has this 4.125 inch raccoon humerus on online.. which is straighter than turtle humerus bones... 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
