: Hello Marion... nice find. I found it so intriguing that I discussed your find with some paleobotany people and they just told me this... Peter

Hi Marion,

Peter also send me the info via e-mail. I think we are getting warmer in finding out what your "rock" is.

I recommned you to look at a just recently released book on Paleobotany entitled "Common Fossil Plants of Western North America", 1998, 2nd edition.

I believe the book is listed in our Bookstore (enter through our home page) and you can purchase it directly via our link to Amazon.com.

Cheers and thanks Peter
