    Otodus obliquus parasymphyseal?

    I found this perfect little tooth today along the Potomac River in Maryland (Paleocene, Aquia Formation), which I think may be an Otodus obliquus parasymphyseal. The root isn't as oversized as megatooth shark parasymphyseals I've seen posted elsewhere on the forum, but it sure looks like an Otodus, is laterally compressed, and is quite tiny compared to other Otodus I've found. @MarcoSr, @siteseer, @Al Dente, and others, what do you think? This tooth bears similarities to another I found from this location several weeks ago (tooth on the right

    Crocodile Vert? and what species?

    I have bought this crocodile vert on a fossil show a few months back and i was wondering if someone could identify what species it came from? I'm not even sure if it is a crocodile vert but it looks like one but since the person who i bought it from didn't know much about crocodile bones it could be something else too. it measures 71.6mm long and 52.0mm wide. for Americans its 2.80" long and 2.04" wide. it was apparently found in Morocco in a Paleocene formation but i have no name of the formation and neither of the exact place where it was found ( i know this is probably gonna
  20. The cover story in the current (June 2022) "Scientific American" magazine is about Paleocene mammals with nice artwork of Ectoconus, an early placental mammal that has previously received very little mainstream exposure. It's a nice summary of what has been learned about groups of mammals from the time between the extinction of the dinosaurs and the evolution of nearly all mammal groups we know today. The author, Steve Brusatte, has also written a new book on mammal evolution (published earlier this month), "The Rise and Reign of Mammals: A New History, from the Shadow of the Dino

    Douglas Point Mollusk

    Interesting shell found at Douglas Point, Maryland which should be Paleocene Aquia Formation. Didn't see an obvious match anywhere online, any ideas?
  22. Collected these in North Carolina this weekend. Angel shark vertebra w/ fossilized cartilage, fish skull cap, mosasaur tooth, soft shell turtle fragment, worn Otodus tooth, goblin shark teeth, crow shark tooth, bull shark tooth, and not sure what the smallest shark tooth is. These come from a mix of Cretaceous Tarheel and PeeDee formations and Pliocene Yorktown formation.

    Fushun Amber (Guchenzgi Fm., 56-50 Ma)

    From the album: Fossil Amber and Copal: Worldwide Localities

    Roughly 200g of small (≈1g) nodules and runs of amber from the West Open Pit Mine in Fushun, China; the mine was closed in 2019, but small pieces of amber are still recovered from coal found in the gangue piles; it is separated from the matrix by mechanical action and immersion in large vats of saltwater solution, and recovered with netting as it collects at the surface. This material is hard, takes a high polish, and is often shaped and drilled to make beads. Its chemical and spectrographic signatures indicate this amber is derived from a cupressaceous source.

  25. Hello to all guys!!!, I would like to ask again for help in the ID of some teeth. I´ve been searching in a local university's museum for teeth of the original strata (Upper Paleocene), and I have found a very interesting set of boxes containing a bunch of different teeth, all labeled as "Scapanorhynchus sp.", maybe existing a missidentification. The question would be if any of you guys can ID the pieces and how to differentiate the Scapanorhynchus sp. from Striatolamia striata or Sylvestrilamia teretidens, the options I´m leaning for the ID of the teeth. I would also li
