danco Posted May 23, 2011 Share Posted May 23, 2011 Here are three, found at Sherman TX, Cretaceous. A is 5.5 cm long, B is 6 cm and C is 4.5 cm. I have also a supposed vertebra fragment, 1.5 cm large (same place). Is it possible to ID the animals? Link to comment Share on other sites More sharing options...
Fruitbat Posted May 23, 2011 Share Posted May 23, 2011 Interesting finds. Picture A and the 'supposed vertebra fragment' don't appear to be bone to me. Pictures B and C, on the other hand, ARE both bone but I'm sorry to say that I can't give you any determination of their source based on what you have. Keep in mind that we get a lot of Pleistocene and Holocene (modern) bones that wash into older sediments. Were these found in a creek/stream/river environment or were they in situ? -Joe Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...

The were found by a riverbed (creek) amongst shark teeth (mostly Scaphanorhynchus and a few Ptychodus). -Joe Link to comment Share on other sites More sharing options...
tracer Posted May 23, 2011 Share Posted May 23, 2011 um, don't think you're looking at cretaceous. the one piece of bone looks sawn, and the other looks spiral-fractured, like it was broken like that while still green. Link to comment Share on other sites More sharing options...
PleistoGuy Posted May 27, 2011 Share Posted May 27, 2011 Interesting... Well, A & C are indeed fossil bone... mammalian or not, cannot tell... and they are almost impossible to determinate... By the other way, B & D are a concretion and a rock respectively... sorry Link to comment Share on other sites More sharing options...
Auspex Posted May 27, 2011 Share Posted May 27, 2011 ...A & C are indeed fossil bone... Did you mean to say "B & C"? I think A is clearly not bone, being composed of coarse, rounded sand grains.
