LoneRanger Posted November 7, 2020 Share Posted November 7, 2020 Took a recent collecting trip to a site that preserves stem-tetrapod, anthracosaur (reptile-like amphibian) footprints from the Mississippian subperiod. As seen in the photos, it's fairly common for these to show an overlap of front and back (manus and pes) prints. As part of the agreement for site access, I can't provide any info on geologic formation or location, but it's not the Union Chapel Mine or any other well-known Carboniferious ichnofossil site. Paleontologist Alfred Romer coined the term "Romer's gap" to describe the lack of tetrapod fossils in the earlies Carboniferous Period (roughly 360 to 345 mya). In recent years, new finds have been made that help fill in this gap, and an internet search on Romer's gap will provide a variety of papers describing interesting worldwide Late Devonian/early Mississippian tetrapod fossil finds. 14 Quote Link to post Share on other sites

Yes, these have been studied and scientifically named, but providing the name would make it possible -- by internet search -- to track down (pun intended) the site!
