MarielleK Posted January 6, 2018 Share Posted January 6, 2018 I have a nice little leaf fossil. I just wanted a quick ID on the species and time period it is from, if possible. It is from the green river formation. I was thinking Macginitiea wyomingensis? Thank you! Link to comment Share on other sites More sharing options...
fossilized6s Posted January 6, 2018 Share Posted January 6, 2018 You are correct, it is a Sycamore leaf. I'm thinking Platanus wyomingensis or Macginitiea wyomingensis. These are from the Eocene. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
