Green Mill Run - Large Bone Chunks

[MC_Hendges]

Hey everyone! On my outings, I usually don't pick up the bone fragments, but I have stumbled upon a rather large pocket of good sized bone fragments that I would love some help in identifying. If no dice here, I'll get whatever is left ID'd at a museum this weekend.

 

Fossil #1 - Going to take my best guess and say a rib of some sort?

 

Fossil #2

 

Fossil #3

 

Fossil #4

 

And finally Fossil #5

 

There is PLENTY more where these came from, I consolidated the other fragments into a small area, so in the off chance anything here is significant, I would be more than happy to retrieve the rest. Thank you for any help you can provide, I know bone fragments are quite common at GMR, but I just found it odd to see so many chunks within close proximity.

Fossil #2

This is a broken tooth still in the jaw segment. The bone doesn’t look like fish material, so I would guess this is mosasaur.

Really? What do you think gives that away in reference to being mosasaur, for future identification’s sake?

could you get more pictures of fossil number 1, from the base.

Will these help? If there’s another angle you want just let me know.

GMR has similar looking Enchodus palatines but they are more solid (less bony like structure) than your fossil so I ruled that out. Like I said before, not really fish like bone. Usually fish bone has a flakey texture. That pretty much leaves Cretaceous reptile or Pliocene marine mammal. The oval shaped pulp cavity looks very much like mosasaur to me. Croc would be round. I've never seen whale tooth look like this. They aren't normally firmly attached to the jaw.

Sorry, but I'm not sure, it could be a rid end.

Awesome, had some second opinions and they all say mosasaur as well. Will look into donating this piece. Thank you!
