Cianfaglione Posted March 26, 2021 Share Posted March 26, 2021 The first time I found this type of triangular marking I thought it was a broken off tip of a much larger plant fossil. Five specimens later (all identical in size and shape including straight-edged base) and I'm now starting to think that this might be a possible pinnae to some sort of cycadophyte. Illustration from the book Introduction to Plant Fossils; Cleal and Thomas. Early Jurassic, East Berlin Formation of Connecticut. Thoughts and comments would be greatly appreciated.

Fossildude19 Posted March 26, 2021 Share Posted March 26, 2021 I think it is a pinna of an Otozamites brevifolis. Can you see any striations on it, Paul?

Cianfaglione Posted March 27, 2021 Author Share Posted March 27, 2021 Yes Tim, there are faint striations on this fossil fragment. The other specimens however have more defined striations. Thank you again for your comments! 1 Link to comment Share on other sites More sharing options...
