Tetrapod Footprints of Maryland
EMP posted a topic in General Fossil DiscussionI've finally got around to compiling some photos of my tetrapod footprints from a road cut here in Maryland. All of these finds come from the early Mississippian aged Purslane Formation, which belongs to the Pocono Group and thus are about 350 million years old. In Maryland the Purslane represents the late Tournaisian through the Visean stages of the Mississippian. These finds are particularly interesting because they come from an era known as Romer's Gap, which was a span of time from the end of the Devonian to the end of the Mississippian where worldwide fossils of tetrapods are rare, and k
