Please help identify some shark teeth

Recommended Posts

The weather has been so nice here lately that I decided to go for my first bike tour of the season yesterday. I don't like to over strain myself on the first trip, so I chose a site in the woods on the edge of a village about 10 kilometers away as my goal, knowing very well that I could spend a couple of hours scratching away in the sand and grit with my pen knife in the search for small shark teeth in the Miocene Burdigalian exposure. I have some idea what 3 of them might be, but I'd nonetheless appreciate confirmation or correction of my assumptions. I'm however not at all sure what the last 2 might be since I see just too many possibilities and am hoping that someone could set me on the right track. @MarcoSr @Al Dente @fossilselachian @Woopaul5

I'll number them for convenience's sake. Thanks in advance.

 

1. Mitsukurina lineata ? Goblin shark lower lateral ? 10mm. long.

I think that the next 2 are both Carcharias acutissima ? Sand Tiger upper anterior ?

2. 19mm.

I think you'll know I can't help. 

But just wanted to say they're very nice teeth. :)

Unfortunately, I'm not that familiar with many Miocene faunas from Europe.  It really helps with an id to start with a shark species fauna list from a site if one is available.  Your ids seem reasonable.  I sent you via PM a Cappetta paper from a Miocene fauna (Langhian age) in France that might help.

Nice teeth Roger, although I can't help with ID's either. If you should happen to find another one of those goblin teeth before June........I could give it a nice home.

There's no limit to what you can accomplish when you're supposed to be doing something else

Ok Kevin. I'll keep that in mind.
