Unidentified Pterosaur? Bone from Kem Kem


Dino9876

Recommended Posts

Hey guys,

Hello, I discovered this bone in a fossil box about a year ago and bought it for only $ 1.5 because it made me look special somehow.
But I do not know to which animal he could belong. For me, however, he resembles a finger bone of a pterosaur.
Can you help me maybe?

The bone is hollow and 42mm (1,7") in size.

 

Kind regards from Germany!

It won't do me a lot of good, but a look at just how hollow it is may be needed. To me it seems a bit too robust for a pterosaur.

Need to see the wall thickness of the bone so an end view of the broken end is needed.  Pterosaur bones are very thin walled.

Can you measure that wall thickness are we looking at 1-2 mm

Yes, on average it is 1mm

Thank you, photos can be deceptive.

I measured a couple of my pterosaur bones from the Kem Kem and they were 1mm or less.   Shape suggests pterosaur so it's possible but not certain.   Like to see what others say.

Could it be a tarsometatarsus from a bird ?

I assume the fossil is only about 40 mm long.

That was my immediate first impression; distal end with the trochlea broken off. The wall thickness suggests that this might have been a flightless (or nearly so) bird.

The bone preservation is so similar to what I find and classify as bird as apposed to any other animal down to how it fragments and compresses its uncanny.

That is what made me think bird.
