RE: Hell Creek Eggshell

The best person to ask about Cretaceous eggshell is Frankie Jackson here at 
Montana State (frankiej@montana.edu). Her research focuses more on the Two 
Medicine Fm, as well as sites in Argentina and Europe, but she would know the 
most up to date info on Hell Creek and Judith River eggshell.

 >Hello Listmembers,

Does anyone know of any ongoing/current studies of eggshell (dinosaurian or 
otherwise) in the Hell Creek Formation?  I can't seem to find much 
literature.  If anyone has a reference or pdf that might shed some light on 
this, I'm all ears.  If anyone has a pdf of

Hirsch, K. F. & Quinn, B.  1990.  Eggs and eggshell fragments from the Upper 
Cretaceous Two Medicine Formation of Montana.  Journal of Vertebrate 
Paleontology 10: 491-511.

I'd love to read it.  BTW, what ever happened to the "Orodromeus" eggs from 
the Two Medicine?  Were all or just some of them reassigned to Troodon 
(Prismatoolithus)?  Have definitive Hypsilophodont eggs been found in North 
America (or anywhere else)?

Thanks very much!

Lee
