Unidentified Plant Fossil from the Cretaceous of Morocco

Description: Along with the fossil fish associated with this fossil locality in Morocco, are found uncommon plants fossils. They are very well preserved as light brown impressions against the tan matrix. The dealer has no knowledge as to the identification of plant fossils. I’m not even sure if they are aquatic or terrestrial in nature. This specimen is a positive/negative. It’s a very nice curiosity piece. If you have any idea of what the identification is, please send me an email.
