I'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 known mostly from a just a few sites in the entire world. As far as I know no tetrapods have been recorded in rocks older than the Mauch Chunk Formation, which is the unit that overlies the Purslane in Maryland (in WV there is the added Hedges Shale above the Purslane, but this unit is absent in Maryland) so definitely some cool finds! I've found what looks to be around two or three different kinds of tracks, some having rounded toes and others having pointer ones. I don't think they're new species, but rather new occurrences of younger species represented in the Mauch Chunk. Most of these footprints are hard to see without a certain angle of light, which unfortunately would obscure most of them in shadows. As such, I've resorted to outlining the shape of the prints in red. Thanks to mstimson for giving me helpful information about them!
