jort68 Posted November 6, 2020 Share Posted November 6, 2020 Hey all, Picked this up as a gift for my girlfriend's brother. Today's his birthday and I figured I'd try and start his fossil collection... I asked the shopowner for details but she said her mother must have received this one something like 50 years ago. Dead end. If anybody has any guesses I'd love to be able to tell him what he now owns! Thank you guys so much! Link to comment Share on other sites More sharing options...
LabRatKing Posted November 6, 2020 Share Posted November 6, 2020 Looks like Green River or a related formation. Whereabouts is the shop? 1 Link to comment Share on other sites More sharing options...
jort68 Posted November 6, 2020 Author Share Posted November 6, 2020 In Los Angeles! Gonna look for green river leaves while I wait for more guesses Link to comment Share on other sites More sharing options...
LabRatKing Posted November 6, 2020 Share Posted November 6, 2020 Full disclosure, that is just a guess. I forwarded the images to my resident botanist as the stuff I know doesn’t leave fossils! 1 Link to comment Share on other sites More sharing options...
Oregon1955 Posted November 6, 2020 Share Posted November 6, 2020 Green River is likely but it also looks very much like something from the quarry behind the high school in Fossil Oregon. John Day formation, bridge creek beds. It has been open to the public since the early 50's. Nice specimen to start off a collection for your girlfriend's brother with. A leaf fossil from there was one of my very first finds. I think you and he might well be able to identify it yourselves. Start with the many sources easily found on the web for flora from the Green River and John Day formations. It'll be fun to let him try before you tell him what the experts on this site will undoubtedly soon reveal. Best of luck to you and the young fossil collector you are inspiring. 2 Link to comment Share on other sites More sharing options...
RJB Posted November 7, 2020 Share Posted November 7, 2020 First leaf looks very much like an alder leaf? Definetly not green river formation. Good luck RB 2 Link to comment Share on other sites More sharing options...

Packy Posted November 13, 2020 Share Posted November 13, 2020 I agree with fossil Oregon. Neat place. Very similar to a Fagus. Also could be a dicot species. Packy 1 Link to comment Share on other sites More sharing options...

If he cares to try a little preparation work, the margins being exposed may help with identification. 1 Link to comment Share on other sites More sharing options...

Fossil Lake perhaps, but it looks pretty similar to the more southerly lake's exposure at Douglas Pass doesn't it ? 1 Link to comment Share on other sites More sharing options...
Bobby Rico Posted November 13, 2020 Share Posted November 13, 2020 It looks a little like a Aleophylus flexifolia leaf thats also found at Douglas Pass, Colorado part of the Green River Formation. Here one of mine for comparison Aleophylus flexifolia Green River 3 Link to comment Share on other sites More sharing options...
jort68 Posted November 13, 2020 Author Share Posted November 13, 2020 I'm so happy to have received all these responses, everyone's reply really helped me to better understand the origin of this leaf. If anyone cares to know, he was thrilled to receive it. Thought it was so cool. 1 Link to comment Share on other sites More sharing options...
