Pleuromya Posted August 5, 2022 Share Posted August 5, 2022 For the Carboniferous, I couldn't make my mind up which of these worms to add, so hopefully it's okay if I add three. Mazoglossus ramsdelli Archisymplectes rhoton Didontogaster cordylina All are from the Francis Creek shale. 5 Link to comment Share on other sites More sharing options...

Your post was Carboniferous, which could be either Mississippian or Pennsylvanian. Since the Carboniferous is a special case, the options could be: Mississippian, then Pennsylvanian Carboniferous, then Pennsylvanian, since Mississippian is lower Carboniferous in much of the world (in my case, I bumped up a stage) Carboniferous only and on to Permian, if no one with Penn material is paying attention 1 Context is critical.

In this game, don't let that paralyze you. Feel free to roll on into the Permian from there. 1 Link to comment Share on other sites More sharing options...

siteseer Posted August 7, 2022 Share Posted August 7, 2022 The extinct shark, Serratolamna aschersoni. It's a common species from the Early Eocene of Morocco but uncommon from the Early Eocene of the Chesapeake Bay region. It does not occur in the Early Eocene London Clay of England. S. aschersoni was apparently a warm water form of the Tethys Ocean that spread into the western Atlantic. It's absence in the London Clay has been explained as that environment having been a cooler, deeper one. This tooth comes from the Early Eocene Bashi Marl of the Red Hot Truck Stop locality at Meridian, Lauderdale County, Mississippi. The Bashi has been described as a member of the Hatchetigbee Formation but I've seen references to it as a formation. The tooth measures 20mm and was photographed on graph paper (1/4 inch squares) for scale in inches. The crown has more of a spearhead shape than most teeth seen. 10 Link to comment Share on other sites More sharing options...

siteseer Posted August 7, 2022 Share Posted August 7, 2022 Here's a bird beak from the Late Pleistocene, McKittrick tar pit site, Kern County, CA. It's about 2 5/8 inches (67mm) long. It might look like two different specimens but it's the same one. The shots were just taken at least several months apart. It might be a vulture beak. 8 Link to comment Share on other sites More sharing options...

WOW, looks deadly! Is that just the beak or part of the skull as well? What is that large hole? Link to comment Share on other sites More sharing options...
