Mystery bones??? North Sulphur River

[shel67]

I found these bone pieces, at least I think they’re bone, in the shallow water of the North Sulphur River of Ladonia, Texas. Any ideas of what type of mammal they belonged to? Thanks in advance!!!

They are pretty worn, but marine reptile seems to be the most common bone from there.

Hi @shel67!

 

Your specimen on the bottom kind of looks like a worn-down turtle neural/vertebral "scute" (carapacial element).  I am definitely no expert, though, so I could be wrong...

Nice "chunkosauruses" the bottom one appears to have the original surface unworn off too.

Ah...one of the 'curses' of the North Sulphur River...the ubiquitous water-tumbled bone fragment.  Unfortunately, I can't really see any diagnostic features on your specimens so the best I can say with any accuracy is that they all appear to be bone.

Too worn to tell. I have a nice rock garden full of them. lol
