Keystone15417 Posted March 3, 2016 Share Posted March 3, 2016 I found this near Fayette City, Pennsylvania at the bottom of a cliff along the Monongahela River. There were a large number of concreations amount the rocks in the cliff. Anyway, this one sort of looked like a crab to me. What are your opinions?

Rockwood Posted March 4, 2016 Share Posted March 4, 2016 It would seem likely that there is a gradient between homogenous sediment and museum quality septarians. Link to comment Share on other sites More sharing options...
