Big rib (?) piece

[Max-fossils]

Hi all,

 

Here is a piece of bone, and I think it's part of a big rib (this being the part connecting the rib to the spinal column). 

It comes from the Zandmotor (NL), which is known for its numerous remains of mammal fossils from the late Pleistocene (40'000 years ago) (mammoth, cave lion, jaguar, dire wolf, woolly rhino, etc).

 

Anyone know from what animal it might have come from?

 

Thanks in advance,

 

Max

i dont think its a rib, i think its the head of a Femur, the part that goes into the pelvis.

You're right, good call!

Definitely not a femur head with those two articulation surfaces. It does indeed look like a rib. Dunno what type of animal specifically. It's not rhino though.

Ah ok. 

Rhino didn't come in my mind at any time, I would imagine that rhino bones are more robust. I was more thinking horse, deer or another large 'gracile" ungulate.

Yes they are more robust on rhinos. But there's also a deeper rounder gap between the two articulation surfaces.

Ok. I guess I'll just keep the bone as Mammalia indet., since no one has a positive ID.
