Hammerhead Tooth?

[jgj1120789]

Found this in a pile of shell fragments today.  I'm terrible at identifying shark's teeth.  From my research online it looks most like the tooth of a hammerhead.  I would like someone more seasoned to have a look!  Any help is appreciated!!

It's an upper Gray shark, Carcharhinus sp., nice find 

 

You can find good examples on the Elasmo.com site.

Hammerhead Shark teeth are a little different here is an illustration from Kent's book Fossil Sharks from the Chesapeake Bay

I also found this.  Really can't tell if it's a rock or tooth.  Anyone have an idea?

Looks like it may be a crown from a shark tooth.
