Hadrosaur Tooth? New Jersey

[frankh8147]

Hello everyone!

 

I found this yesterday in a Cretaceous stream in Monmouth County, New Jersey. It measures 3/4th of an inch long. I was thinking Hadrosaur but I've never seen one this thin so I figured I would look for some other opinions.

 

As always, all help is greatly appreciated!

I would guess some type of fish bone.

my knowledge is too limited to confirm what you have, but I am excited about it.  My only concern is that it is very narrow, I expect hadrosaur to widen in the middle, but I can not think what other enamel like structures have that particular oval depression.  There have been hadrosaur teeth found in those creeks in NJ This is probably  one to confirm at a museum

Thanks for the replies! Fish bone was on my radar as well. 

 

@10313horni probably will end up showing it to the State Museum if we can't come up with anything definitive.

Maybe something like part of a fish parasphenoid or basipterygium.
