Looking for Paleocene/Eocene shark dentition resources

Recommended Posts

Hi all, I'm looking for photos or good illustrations of dentitions from a few different sharks from the Paleocene and Eocene to help improve my recognition and to learn better how their teeth varied across the jaw. These could be natural/associated sets or artificial/constructed ones.

 

The sharks I'm looking for are:

  • Jaekelotodus robustus
  • Palaeohypotodus rutoti
  • Brachycarcharias lerichei
  • Isurolamna inflata

 

Can anyone point me toward resources for any of these? If you know of dentitions from different species within these genera, those would be helpful as well.

 

Thanks!

Hi there,

 

Elasmo has a decent set online for Brachycarcharias

 

Artificial set: Brachycarcharias lerichei

http://www.elasmo.com/frameMe.html?file=genera/cenozoic/sharks/brachycarcharias.html&menu=bin/menu_genera-alt.html

 

Cheers,

Brett

Thanks @Brett Breakin' Rocks! I was looking at the separate fossil tooth sets section of the site and forgot to check out the genera pages. I wish they had the lingual faces shown too, but that is a very helpful image.

Hi B,

 

I'm not aware of a dentition for Isurolamna, J. robustus, nor Palaeohypotodus.  David Ward might have "puzzles" he's working on.  Gordon Hubbell has a partial dentition of J. trigonalis but it's a weird one (probably because it happens to be from an aged individual) proving that there's a lot of variation in species.  Look at the examples on elasmo and check other sites for rarer jaw positions.
