Unknown piece from Miocene of Calvert Formation

Recommended Posts

Hi all!

 

Decided to bring out the kayak on this windy Maryland day and it was another amazing hunt although and my arms are definitely suffering. Unfortunately didn't find anything too great but did find an unusual piece  of something I've never seen or found before. Of course like every leaf, shell, or rock it could just be an incredibly suggestively shaped piece of nothing but I think it's some sort of mammal tooth possibly or maybe some type of fish tooth? Comparing it to the seal/peccary online it looks similar but just not enough to convince me so I thought I'd ask the experts!

 

It's from the Calvert formation of the Chesapeake Group which is early Miocene:

Thanks and I apologize for the blur I guess that's what you get with a clip on magnifier on a cell phone camera :wacko:

I would be more convinced if we knew what it came from. To be honest, I don't see jaw or teeth, just bone.

Having a view of the ends would be nice.

I’m fairly sure that this is a wahoo jaw, they are pretty distinctive.

New one to me. Do they have an oversized foramen in them ?

Wahoo have teeth unfused to the jaw bone, so I don't think this is from a wahoo.  I don't have much experience with these fish, but I'm leaning toward sawfish rostrum.  The fish experts need to help us here.

Their jaws are hollow.

Looks like a piece of Wahoo jaw to me also.

Interesting. How old do the experts think this is? Is it related to the Wahoo that I am happy to consume upon occasion as "Ono"? Is it miocene, like a lot (if not all) of the sharks teeth are that are found near Calvert Cliffs?

Miocene, in the same genus as the modern Wahoo though I don’t know if the species has been named yet.
