Hello, I am a PhD student in sedimentology and biostratigraphy, and I have a fossil leaf specimen from a Jurassic-Cretaceous deposit. I would like to receive recommendations on fossil plants used in stratigraphy, especially the upper jurrasic and lower cretaceous. Additionally, if possible, could someone help me find specialists or relevant articles on Jurassic and Cretaceous fossil plants?
Thank you very much for your assistance!
