Fossil ID Help: Four Teeth and a Claw?

[Kribensis]

I acquired a collection of fossils in Florida. About half were labeled but the rest were not. These five fossils were in a box with a Fossil labeled Polished Whale Tooth Miocene Cooper River SC and one labeled Fossil Dolphin Tooth Venice Florida. 
 

I am guessing 1, 2 and 3 are whale tooth fossils and 4 is from a dolphin.  I have no idea what animal 5 is from but am guessing it’s a claw.  The back of 2 has metal protrusions with glued paper around them and I am guessing was part of an old display. 
 

Any help identifying these is greatly greatly appreciated.

# 4 is a Turtle claw.  Claw 5 above it looks like a replica is it very light?

[Kribensis]

The last image was misplaced.  It’s a close-up of 4.  Still think it’s a turtle claw?  I obviously have no clue. 
 

I also think you are right about the claw. It is very light.

In number 3, I think it is also a replica, it shows how when applying paint. The marks of the brush are very noticeable. 

 

If you want, you could touch with a hot needle a hidden part of each piece, if it melts, it is plastic. 

 

Good luck anyway.

Yes 4 turtle and agree 3 looks like a replica Tyrannosaurid tooth

3 is definitely not plastic though of course that doesn’t mean it’s not a replica.  I’ve had replica megalodon teeth pass the pin test.   That said, I agree it’s probably a replica.  
 

Excited about the turtle claw. Any ideas on the first two?

#2 is what it says it is... SPERM WHALE TOOTH.  specifically Scaldicetus .sp.  I do not believe that it is a replica.

#3 Maybe it's resin. In that case, the pin test won't do much good. I have a replica of that material and instead of melting, they become like dust. I don't know if I explain myself well. 

 

#2 seems more real to me, it has more texture details and colors that are difficult to replicate in an artisanal way. Is those pink marks something that's glued together, or is it paint? 

[Troodon]

I do think the whale teeth are real.  BTW The #5 claw is most likely resin of a theropod hand claw

I completely agree that 3 (theropod?) & 5 (dromaeosaurs?) are painted casts. 1 & especially 2 look like legit fossil whale teeth. 4 is very hard to read, could be cast or real, could be claw or horn.

Thank you all for your help identifying these.  I agree that 3 & 5 are casts.  I have no doubts now that 1, 2 and 4 are all real with 1 and 2 being fossil Scaldicetus teeth and 4 being a turtle claw.  Wouldn't have identified them without all of your help - even though one of them embarrassingly had what it was written on it which I missed! 

 

I have more from this estate purchase that I will be posting that I haven't been able to definitively identify.  This site is amazing.  Wish I had found it years ago.
