Re: Not dinosaurs but chondrichthyans

["Patty Ralrick" <pattyralrick@hotmail.com>]

Hi Lorna,

I recently co-wrote a chondrichthyan guide to Dinosaur Provincial Park in 
Alberta, Canada with Dr. Don Brinkman of the Royal Tyrrell Museum.  After an 
extensive search the oldest shark I could find was *Hybodus* who was known 
from the Devonian.  Sorry.  Wish I could give you an older one, but there 
doesn't seem to be any known yet.

Good luck on your display!

Patty

Hi all,

Is anyone out there up to date with the earliest appearance of
chondrichthyans? It's Devonian according to the latest edition of Benton's
Vertebrate Palaeontology, but surely there have recent finds to push that
back a little earlier. Shark people, please tell me what you know! It's for
a museum display.
