I found a group of leaf fossils, could not resist them.  I know they are from the Green River formation of Utah; Eocene age.  Are these Cuercus petros?  I've looked over a lot of specimens from that area; these SEEM to match.  (Except for the first photo.... not sure WHAT that one is!  Leaves.... but from what?)  I think I am developing a plant fossil obsession!

 

On another note - While I LOVE to hunt fossils, I DO buy specimens, so that I have an in-hand model to use for comparison and learning!!!!

I like Trilo-butts and I cannot lie.

Nice finds,7!

Btw,Wilf lists Q.alba,coccinea,prunus,rubra,velutina for GR oaks.

What's the source of your info on "petros"?

Or did you NOT used it here as a species name?

I did use it for a species name!  I tried to compare it to all of the leaf specimens from this area that I could find.... petros seemed a match, but I am not sure!  So, I posted, hoping someone would have an idea!

There's a guy in the Cyprus (the Mediterranean island, that is) Forestry Service called Petros, who has written a piece on Quercus alnifolia.:P

edit:'kay,goddit.

The name might be Quercus petraea

Quercus petros was described and illustrated in H. D. MacGinitie. 1969. The Eocene Green River flora of northwestern Colorado and northeastern Utah.

The first one looks close to Lomatia lineatulus.

Thank you, everyone!  Great information.  I think these leaf specimens (except the first one) are Quercus... do you think Petros ???  I am leaning in that direction!

Maybe Quercus (?Q. petrosus), but I'm not an expert in the Eocene Green River flora. :)
