ID of possible intervertebral disks

Recommended Posts

Hi guys! I haven't been on TFF for AGES but am getting back in the groove. My question for y'all today is regarding these fossils. They are Pleistocene cave bear fossils from Romania. I bought these as juvenile intervertebral disks. Is that what these are? They are much lighter and led dense than verts. I'm curious.

These are called epiphysis plates.  They eventually fuse onto the vertebra with age, so by definition they are from a juvenile. I've seen many from marine mammals, but never a bear before

Here is an example from Romanian Cave Bear I have.

Ahhh. I'm thinking that maybe these were from prenatal bears so haven't been compressed at all yet.

I'm sure they are cave bear as they were part of a lot of Romanian cave bear material.
