peacefossil Posted October 10, 2010 Author Share Posted October 10, 2010 Looks correct, mine is just worn down. The curve of mine didn't seem to fit horse though. Anyone on the other item? Link to comment Share on other sites More sharing options...
tracer Posted October 10, 2010 Share Posted October 10, 2010 a lot of pieces of bone that you might find will have been so tumbled by active water that there just aren't enough features left to identify. this seems to be one of those bones. having said that, the fine grain and very limited "spongy bone" showing pushes me sort of toward thinking maybe sirenian bone, like from a dugong or manatee. those animals have "thickened" bones (called pachyostosis), probably for reasons having to do with buoyancy and limited need for structural strength due to their somewhat sedentary nature. (do i anthropomorphize? very well then i anthropomorphize.) so anyway... Link to comment Share on other sites More sharing options...
worthy 55 Posted October 10, 2010 Share Posted October 10, 2010 The teeth on the left could be bison/cow. It's my bone!!! Link to comment Share on other sites More sharing options...
tracer Posted October 10, 2010 Share Posted October 10, 2010 The teeth on the left could be bison/cow. yeah, and i think a see a stylid peeking from the one on the lower right too. not the precise comparative material for this specimen. hang on a sec...

Yes, that one also and the rest look like horse. Edited October 10, 2010 by worthy 55 It's my bone!!! Link to comment Share on other sites More sharing options...
tracer Posted October 10, 2010 Share Posted October 10, 2010 ok, well, for the occlusal surface, then check here. i don't really want to be rude and link to someone's veterinary practice for fossil references, but say by chance you were to search google images for "horse dentition", you might find a cool cached cutaway picture of the side of a horse's skull showing all the teeth...

peacefossil Posted October 11, 2010 Author Share Posted October 11, 2010 Tracer I understand it is worn down, but doesn't appear to be broken. I thought those curved depressions on either side would be enough for an id. Thanks for the help. Another one for the unknown drawer Link to comment Share on other sites More sharing options...
Fruitbat Posted October 11, 2010 Share Posted October 11, 2010 The tooth is definitely from a horse...upper jaw. As for the other thing...to be honest, I'm not even sure it is a bone. -Joe Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...
peacefossil Posted October 11, 2010 Author Share Posted October 11, 2010 Gotcha. Looks like bone and feels like bone not a rock. With the knowledge base on here I'm sure there will be an answer. I can post more pictures later from the sides. Link to comment Share on other sites More sharing options...
tracer Posted October 11, 2010 Share Posted October 11, 2010 ok, just to clarify a bit what i was saying earlier, here are two pictures (ignore the acorn cap prop) of a piece of worn pachyostotic bone, which i consider likely to be a broken chunk from a manatee rib. this type of bone is very different from "normal" mammal bone in its granularity and how it wears. it can have worn broken ends that don't look like broken ends, and i have not seen any other mammal bone that looks like that. note the propped up right end of the first picture - the porosity and apparent grain doesn't really change much as it wraps around the end, unlike the distinct difference between the outer, "cortical" bone surface and the inner "trabecular" or "spongy" bone on most bones...

fossillarry Posted October 28, 2010 Share Posted October 28, 2010 The tooth is an unworn upper 3rd molar of a horse. It is probably a hipparion horse from the Upper Bone valley Age equivalent of the Peace river. Link to comment Share on other sites More sharing options...
