Bone Valley Astragalus ID Needed


Meganeura

Recommended Posts

Found this Astragalus today - and I can’t figure out if it’s Horse or Tapir. Seems too big to be a tridactyl horse astragalus, but the deposit I was digging in does NOT contain Equus - only tridactyl horse fossils have been found. Which leaves me thinking Tapir. @Harry Pristis @Shellseeker

I strongly believed that mine was Horse.. based on size..

Interesting! As I said - no Equus teeth have been found in the dig site yet. My initial thought was horse though. Suppose I need to start going with my gut!

Fossils? I dig it. :meg:

So I'm not sure if I'm explaining it correctly, but from my viewing examples from horse and tapir, if it were tapir I would expect both big articulations to terminate roughly equidistant from the red line.  On horse, one terminates right on the line and one terminates noticeably higher.

That makes sense to me! And is definitely something I’ll keep in mind next time I find one.
