Flag Ponds unidentified bone

[Petalodus12]

Hi all,

Apologies for being gone for so long. I have been busy with pretty important research for my (hopefully) undergrad thesis.

 

Anyways, I found this bone a few years back at Flag Ponds Nature Park in Calvert County, Maryland. It's Miocene in age.

 

I know that most bone chunks coming from float from the cliffs are unidentifiable but this one seems to have some diagnostic characters considering the amount of foramina running through it. I could be wrong, however. That's why I study fish, not cetaceans!

Thanks all in advance.
