    DD13: The Morrison Formation

    The Morrison Formation is arguably the most prolific and famous dinosaur-bearing formation (maybe after the Hell Creek). It has some of the most well known dinosaurs, and not coincidentally was also the site of many Bone Wars skirmishes between Cope & Marsh. The Morrison Formation was quite a stable ecosystem (for millions of years) Baby sauropods were probably a major food source for other dinosaurs in the Morrison Formation

  4. I Know Paleo Episode 38: Prehistoric Sharks

    I Know Paleo Episode 38: Prehistoric Sharks

    We go through six major groups of sharks that evolved in the Jurassic (or earlier): Hexanchiformes: Includes frilled sharks and cow sharks. They have 6 (or 7) gill slits instead of the usual 5, give live birth, and some modern species look remarkably similar to their fossil ancestors (making them "living fossils"). Heterodontiformes (Bullhead sharks): Named for their two types of teeth—sharp front teeth for grabbing and flat rear teeth for crushing hard-shelled prey. They lay "auger" style spiral-shaped eggs that wedge into tight spaces. Orectolobiformes (Carpet sharks): Named for their ornate tapestry appearance. Many are camouflaged bottom-dwellers, like the tasseled wobbegong, which hides on the seafloor to ambush prey. Carcharhiniformes (Ground sharks): The largest group with over 270 species (roughly half of all living sharks). Named for their streamlined "sharp nose". Today, this group includes tiger sharks, hammerheads, and catsharks, but they hadn't evolved yet in the Mesozoic. Squatiniformes: Flat-bodied, bottom feeders with almost ray-like fins. They evolved into modern angelsharks during the Cretaceous. They have specialized gill flaps and can bury themselves in sediment for up to 10 days waiting for prey. Lamniformes (Mackerel sharks) — The group includes megalodon, great whites, makos, goblin sharks, and large filter feeders like the megamouth & basking sharks. They likely evolved in the Jurassic or very Early Cretaceous. Featured Creatures include true sharks as well as shark like fish: Xenacanthus (Carboniferous/Permian): small freshwater fish known for a big spine coming out of its head Stethacanthus (Devonian/Carboniferous): Weirdo with an "anvil-shaped" fin on its back Helicoprion (Permian): Even weirder shark with a giant whirl of teeth in its mouth Scapanorhynchus (Cretaceous): Creepy goblin-shark looking apex predator Cretoxyrhina (Cretaceous): Nicknamed the "ginsu shark" for its sharp teeth with extra enamel

    DD12: Commercial Paleontology

    The debate about whether commercial paleontology (selling fossils) is good or bad is complex. We share our opinions (backed by some recent examples and studies) more openly than we do on our public podcast. Why are fossils valuable? source Are Spinosaurus teeth illegal or immoral to buy? source One of the first big modern dinosaur sales was in 1993, a nest with 10 eggs that was found in China source Update on Spike the caenagnathid which sold in December for about $4.6 million USD source An art historian's take on the for-profit fossil trade source

    I Know Paleo Episode 37: Coelacanths

    This group of "lobe-finned fish" is more closely related to us than to other fish. Their fins/flippers eventually evolved into the limbs that all living birds, mammals, amphibians, reptiles, and other tetrapods have today. The coolest thing about them may be that they are still around today, with surprisingly few changes since their Devonian ancestors 400 million years ago. The woman who first brought them to the attention of modern scientists, Marjorie Courtenay-Latimer, is also a legend in her own right.
