Mammal teeth, ear bone Myrtle Beach

[csrlewis93]

Whenever I find something I always like to try and find out, on my own, what it is. I've searched and have an idea of what these might be but this forum is so helpful I thought I'd ask for some ID help. All were found on Myrtle Beach...despite the busy season here now I still find some nice stuff. Ruler is in inches.

 

1: 

 

 

 

 

2: Looks similar to the tooth above. Love the blue-ish color of this one.

 

 

 

3: Looks to be a tooth.

 

 

 

4: I'm glad I knew about these beforehand otherwise I would've thought it was just a randomly-shaped rock. I recognize it's a periotic bone, probably dolphin, but could that be narrowed down?

pictures 1 & 2 are cervid, 3 dugong?/mannatee?, But wait for the experts on this one, this is just my opinion.

Yes, periotics can be narrowed down.  This may help:
