handinpalm Posted August 5, 2010 Share Posted August 5, 2010 I found this bone, I believe, North of Yellowstone NP. It was in a large stream close to the Yellowstone river. What are your thoughts? Is this a dinosaur bone fossil? Looks like the bone is cracked in half, showing where the marrow channel was. Link to comment Share on other sites More sharing options...
Tony Eaton Posted August 5, 2010 Share Posted August 5, 2010 I'll let the experts weigh in, but I have to say you are not the first to ask this question, but perhaps the first to ask the question and be right or at least in the ballpark. Maybe it is a mammal bone. Cool find! :-) Link to comment Share on other sites More sharing options...
