Cretaceous Teeth for ID

[Amazing Relics]

Hello forum friends, 

I have another batch of teeth I’m trying to ID. I’m not sure but I think 1, 3 & 4 are the same. #2 I believe to be troodontid and specifically Stenonychosaurus sp. 

#5 is pretty cool with that huge root but no clue what it belongs to. Thanks for looking and any input!

1,3 and 4 look crocodile, but I'm no expert. Nice looking teeth!

Seems logical that @Troodon might be able to help.

Are all of these from the Hell Creek Formation if so

1, 3, 4 Crock,  Borealosuchus or Brachychampsa cannot distinguish anterior teeth

2 is Stenonychosaurus sp.  Premaxillary 

5 is a mammal incisor , believe its Didelphodon vorax?

Wow, thank you Troodon! They are all from the Hell Creek near Jordan, Mt.

Stenonychosaurus?  Now I have to go look that up.  The mammal incisor can be labeled as D vorax primarily based on size.  It is the biggest mammal in the Hell Creek.

@jpc,

Stenonychosaurus inequalis is the previous name for the Troodontid Troodon formosus.

 

It was synonymized with Troodon formosus by Currie years back. Very recently Currie has corrected this due to new specimen data and now believes Troodon formosus is a nomen dubium and has reinstated Stenonychosaurus inequalis as the proper genus and species name.

Nice bunch of teeth! 

The Stenonychosaurus is very beautiful and the Didelphodon very interesting
