araucaria1959 Posted January 20, 2013 Share Posted January 20, 2013 Hello, here are a few plant fossils I bought a few years ago on a fossil exhibition in Germany. The only information I got is that they are from Oregon, though I don't know how valid this information is. They are for sure somewhere from the United States. To know about the locality would help to identify stratigraphic age and the genera of the fossil leaves. So I hope the stuff is so typical for a known locality that it can be said where it comes from. For this reason, I show also the back of some specimens (Plant-R1, Plant-R2) even if there are no leaves. Maybe there are some lithological features which are characteristic for a special locality. IDs are also welcome. Pic Plant-3b shows some feeding traces on a leaf. But I wonder if the holes on the leaf in pic Plant-11 are feeding traces (or other damage caused by animals) too? Thanks! araucaria1959 Link to comment Share on other sites More sharing options...
araucaria1959 Posted January 20, 2013 Author Share Posted January 20, 2013 (edited) Since - for technical reasons - it seems impossible to load up the missing pictures as an answer to my first posting, I must open a second thread to show the other specimens and the backs of some specimens. I must attach these pictures since I referred to them in my first posting. (Since upload is limited to 2 MB, I wanted to upload the missing pictures as an answer to the first post, but this didn't work). araucaria1959 EDIT: Merged Edited January 20, 2013 by Auspex Link to comment Share on other sites More sharing options...
Rob Russell Posted January 20, 2013 Share Posted January 20, 2013 I'm sorry I can't help with any of the information you're looking for, araucaria. But wanted to comment on the beauty of these fossils! The preservation is phenomenal! I hope someone will be able to help you in your quest for answers. Thanks for sharing your acquisitions!

piranha Posted January 20, 2013 Share Posted January 20, 2013 Hi araucaria1959, These are reminiscent of the flora and lithology of the Oligocene of John Day. Of the numerous units, these could be from the Wheeler High School locality. LINK Congrats on the fantastic flora Link to comment Share on other sites More sharing options...
Shamalama Posted January 21, 2013 Share Posted January 21, 2013 Wow, those are really nice! -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
araucaria1959 Posted January 21, 2013 Author Share Posted January 21, 2013 (edited) Hi piranha, thanks for the information and the link. I'm still searching with the help of some catchwords, but I made some progress. It seems to be stuff from the Bridge Creek Flora (early oligocene) which is present at the localities you mentioned. Beside of this, I could resolve the mystery of pics 3+4. I already considered the possibility that this is a part of a fish, but now it became clear that it's a catfish.
