Earendil Posted May 14, 2021 Share Posted May 14, 2021 Hello, Can anyone help identify this leaf with crenately lobed margins from the Florissant Formation? It sort of looks like a flower petal, even though that's probably a long shot. It's really prehistoric looking and it caught my eye! I haven't seen any leaves like it from the Florissant area. Thanks in advance for the help! Aforementioned leaf is approximately 7/12 inches long. "Its webs of living gauze no more unfurl; Wrecked is the ship of pearl!

Top Trilo Posted May 14, 2021 Share Posted May 14, 2021 I'd lean towards leaf instead of petal, as for identification not sure, due to size it might be a younger leaf which is why it might be throwing us off, maybe a small fagopsis sp. “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

Picture is of two specimen. A sizable leaf and a tip piece along with negative molds and whatever. Link to comment Share on other sites More sharing options...

Be careful about throwing Fagopsis around. I see a lot of misidentified "Fagopsis" that is actually Rhus species online. One Rhus species is top 10 most abundant with a second one top 20 most abundant. From what I had seen of the book, the environment of the Florissant Fossil beds more resembles California Sierra Nevada so keep that in mind. Classic western environment with a bit more moisture than usual, which is very different from present day Florissant location. Link to comment Share on other sites More sharing options...
