Mariopteris nervosa Fern Fossil From Mazon Creek


Above is an image of a seed fern plant fossil called Mariopteris nervosa (Brongniart) Zeiller. This plant fossil dates to the Carboniferous (Pennsylvanian) Period. It was found Mazon Creek, Illinois, USA and appears to be made of chocolate (only kidding). 

The fossil was on display in the Evolving Planet section of the Field Museum of Natural History in Chicago Illinois, USA as of August 2020. Accession number is PP46034. They have quite an extensive collection of Mazon Creek fossils at the exhibit.
