A few bone pieces

[Miocene_Mason]

Found two bone bits at brownies (Miocene, Marine. Calvert FM) That I need some help with.

 

First up is a big old hunk (like 2.5 inch’s which is a bigger chunkosaurus than I’m used to). Wonder if it’s identifiable? It’s also got a line in it, maybe predation marks? Maybe it’s just wishful thinking l.

Sorry for bad pics, I’m impatient. Hopefully I’ll get some sunlit ones with scale on the morrow.

Secondly, this wierd little bone (1.5 inch’s around). This is the second one like this I’ve found. Was going to donate one to the CMM (which I still plan to do) and ask what they thought it was. But as aforementioned I am impatient. Also gonna get better pics for these.

Do not think it is easily identifiable but the first could be even osteoderm like. The age of the deposit would be helpful.

I think I said, it’s Miocene (early to mid). My pictures are bad (didn’t get a chance to take more) but it’s definitely not a scute.

This is a caudal vertebra from a cetacean.

I found some Similar specimens online labeled cetacean cervical vert, thanks for setting that straight!

Could the one with holes in be a water worn jaw?
