Re: mammals over dinosaurs in continuous sequence
In a message dated 99-04-14 19:15:56 EDT, you write:
All these responses are very interesting, but the question being addressed
where in the world is there a K-T boundary sequence with dinosaur fossils
below the boundary and no dinosaur fossils, only mammals, above it. Whether
or not there are mammals along with the dinosaurs below the K-T boundary is
I'm very sorry that my question doesn't pass Dinogeorge's test of
importance. However, I am very interested in Glen Jepsen and his work. As a
result, I am very curious about the fact he felt mammals were rare in the
Lance when one of the best Late Cretaceous mammal localities was only 50+
miles from his ranch. This is important to me, if not to Dinogeorge.
Also, if it's O.K., D.G., I would like to tell John Bois that the
collections at Princeton were transfered to Yale several years ago.
If you want to see Tertiary mammals imbedded in Cretaceous sediments, try
Paleocene Bug Creek localities in McCone County, Montana. Dinosaurs are also
present but have most likely been reworked. So far, no articulated dinosaur
skeletal segments have been recovered from Paleocene deposits that I know of.
