tracefossilnut Posted February 15, 2013 Share Posted February 15, 2013 Brentwood formation Washington county Arkansas. The Brentwood has sequences deposited by tropical storms in middle shelf environments in which we sometimes find terrestrial plant fossils. The first one was found Feb. 5 and has leaves and stems I believe to be Myrica. The others were found different dates- same location : calimites, Neuropteris, and Mucuna (sea bean pods.

PA Fossil Finder Posted February 16, 2013 Share Posted February 16, 2013 Sea beans! I have a collection of modern sea beans, including Mucuna urens, M. fawcetti, Dioclea reflexa, Caesalpinia bonduc, Canavalia rosea, and lots of others. I didn't know that they could be fossilized! Mucuna species live in the jungles of South America. Stephen Link to comment Share on other sites More sharing options...
tracefossilnut Posted February 16, 2013 Author Share Posted February 16, 2013 I hav'nt been able to find any information on fossil sea beans. My fossil hunting friends who recently made a trip to south Texas told me what they were. The seeds float and arrive on s. Texas beaches from s. America. The fossils look like m. sloanei. When I found the first one, I thought it was just an odd concretion and almost discarded it, then I found the second one which had the hinge like thing also and decided to keep them. If anyone knows anything else thet could be or has any information on fossil sea beans, let me know. Link to comment Share on other sites More sharing options...
Auspex Posted February 16, 2013 Share Posted February 16, 2013 "Sea Beans" are from Angiosperms (flowering plants), which are predated by Neuropteris by about 175 million years; Carboniferous 'seeds' would be from the seed ferns in the coal measures, like Trigonocarpus and others.

tracefossilnut Posted February 16, 2013 Author Share Posted February 16, 2013 I guess this means they couldn't float back through time. Maybe I should have posted them under fossil humor as fossilized hamburgers from the Sponge Bob formation! Link to comment Share on other sites More sharing options...
