weaverja Posted December 8, 2017 Share Posted December 8, 2017 I would like to have some help to identify this fossil. I know that it is fossilized, and I am pretty sure that it is a mammal femur, but I would like to find out what mammal and if it is for sure a femur. It was found in Northeast Oklahoma, and I am adding as many pics as I can with scale. So thanks for all the help that you can give. Link to comment Share on other sites More sharing options...

TXV24 Posted December 8, 2017 Share Posted December 8, 2017 Hi @weaverja Sorry to be the bearer of bad news but this fossil looks too badly degraded to be able to say anything for certain. Also are you sure it's bone? It might just be the images but I can't see any bone-like texture (although the hole through the middle could be a marrow cavity). As far as I can tell from geological maps the bed rock of north east Oklahoma appears to be predominantly palaeozoic, long before mammals appeared. There are some quartenary river deposits that could possibly produce large mammals so if it is a bone it would likely be from there, but I'm afraid what mammal it would be from would be very difficult to say.

weaverja Posted December 8, 2017 Author Share Posted December 8, 2017 I appreciate the help and Do I know for sure if it was a bone, no, but it sure looks like it. Link to comment Share on other sites More sharing options...
JohnBrewer Posted December 8, 2017 Share Posted December 8, 2017 Had a little fiddle with the images to try and get more detail. I don’t think it’s bone tho, just can’t see any bone texture. John Map of UK fossil sites Link to comment Share on other sites More sharing options...
ynot Posted December 8, 2017 Share Posted December 8, 2017 Welcome to TFF! I will agree with the others, do not see any bone texture / cell structure. I think it is a concretion.

Fruitbat Posted December 9, 2017 Share Posted December 9, 2017 weaverja... Welcome to The Fossil Forum! Unfortunately, I'm going to have to hop on the 'not a fossil' bandwagon here. I'm not seeing any signs of the cancellous (spongy) inner bone that should be present. What it IS, I can't begin to guess. That hole in the center had me fooled for a couple of seconds, but I don't believe that it is bone. -Joe Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...
Sagebrush Steve Posted December 9, 2017 Share Posted December 9, 2017 The hole in the center looks almost too round to be natural, and looking down from the top the wall thickness is very uniform. Any chance it could be some sort of old cement piling that perhaps held a round wooden pole that has long since decomposed? I’m not used to seeing concretions that look like that.

weaverja Posted December 11, 2017 Author Share Posted December 11, 2017 Well, If it is a concretion, How was it formed? How old and also how young could it be? Link to comment Share on other sites More sharing options...
oldtimer Posted December 11, 2017 Share Posted December 11, 2017 Welcome to the forum. Where in the NE did you find this? I live in the NE Oklahoma area too. Most of what we find are fossiliferous concretions of things from the Devonian and Carboniferous periods. The hole is very interesting though.

weaverja Posted December 11, 2017 Author Share Posted December 11, 2017 I found this on the west side of Grand Lake, all the info on this I can get would be great. Link to comment Share on other sites More sharing options...
