Confirmation on cowshark teeth

Recommended Posts

I was revisiting some of the shark teeth I've found on previous adventures in order to make a list/catalog of the vertebrate species present in my collection. I found a few teeth which I believe could come from notorhynchus or hexanchus and I wanted to confirm that with members on the forum. I was looking at some of my teeth from the spoil pits of Aurora, NC and the Peace River, FL.

1. Deep rooted specimen with what looks like what would be the first crown preserved. Found in Aurora. About 2 cm from top to bottom, 1 cm wide.

2. Unsure about this one, initially thought it was a tiger shark, but it's rather long at the base and doesn't have the curved root like your average tiger. Found on the Peace River. About 1.4 cm wide and .75 cm from top to bottom.

3. This is the one I'm least confident about, but the root is very wide. 1.4 cm wide and .8 cm from top to bottom.

Hi,

 

I think the 1st one is Hexanchus, and 3 Galeocerdo

The first tooth is Notorhynchus and the other two are Galeocerdo.
