ID help - teeth from NJ brooks

[Vae70]

Hi folks, found a couple teeth i'm having trouble identifying

 

1 - Croc or mosasaur?

2 - Sawfish rostrum?

3 - ? These ones confuse me, they seem like badly worn Goblin teeth but the root doesn't align with the usual ways we see goblin shark teeth fragment - are these something else?

No clue whatsoever on #1, #2 is a Sawfish rostrum, as you said, and #3 are all Goblin/Sand Tiger with water worn roots as well as tips.

I think #1 will go croc. , but I'm no expert. 

#2 is a rostral denticle from a sawfish.

I concur. In addition,  #1 is indeed a crocodile tooth (a rather nice specimen too!), which you can tell from the tooth's overall bulbous shape, the striations it carries and round root. The first photograph moreover preserves traces of a carina...
