Strepsodus Posted April 30, 2017 Share Posted April 30, 2017 Hi. I found this in the British Coal Measures. I think it is a limb bone. Is it a limb bone? If so, is it from a fish or an amphibian? Thanks, Daniel Link to comment Share on other sites More sharing options...
Fossildude19 Posted April 30, 2017 Share Posted April 30, 2017 Daniel, Sure looks like one (amphibian bone) to me, ... femur or humerus? Not sure. Excellent find, though.

fossilized6s Posted April 30, 2017 Share Posted April 30, 2017 I agree with Tim. Very exciting find.

Fossildude19 Posted April 30, 2017 Share Posted April 30, 2017 Some blown up shots: I suppose it is also possible that it is a finger bone, from a larger tetrapod.

Do you think Rhizodont limb bone can be ruled out? Thanks, Daniel Link to comment Share on other sites More sharing options...
fossilized6s Posted April 30, 2017 Share Posted April 30, 2017 This looks like a femur of a creature that probably had well developed limbs, so that would rule Rhizodont. I would investigate Silvanerpeton or a similar species. 2 ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
Strepsodus Posted April 30, 2017 Author Share Posted April 30, 2017 Hi. Thanks for your help. Is this line in the middle near to the end only seen in more developed limbs? Thanks, Daniel Link to comment Share on other sites More sharing options...

Thanks, Daniel Daniel, Although I wouldn't completely rule out lobe finned fishes, I would lean more towards amphian on this one.

fossilized6s Posted April 30, 2017 Share Posted April 30, 2017 Your fossil looks so close to a ichthyostega femur it's scary. But these are from the Devonian. These creatures are thought to be the missing link from fish to Amphibians. And the evolution of the ball and socket joint gave these creatures a larger range of motion in their limbs to eventually walk, hop, run, etc. 1 ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

Fossildude19 Posted April 30, 2017 Share Posted April 30, 2017 You could try to contact Dr. Jennifer Clack. She has been responsive to other members with similar questions. Good luck.
