July 31, 2020016 - The Scoop on Dino-poop (Borealopelta and Gryposaurus)ReferencesDiscussion of evidence of late sauropods (titanosaurs) eating grasses in India, as seen in their poopRhamphorynchus with a big ol’ fish in its stomachTurns out herbivorous dinosaurs ate plants. This paper is far less about what they ate and far more about how we know we’ve found stomach or gut contents (enterolites or cololites).Evidence of dung beetles in dino poop!Carnivorous poop fossilizes better than herbivorous poopT. rex poop! But in fancy science words.Maiasaura ate woodIncredible preservation of muscle in a dino-poop“Herbivore” doesn’t necessarily mean what you think it does: it seems some plant-muncher was also chomping on crustaceans.Telling fossilized poop from fossilized vomit: harder than it sounds.Want more info on how coprolites and similar terms were named? Well have I got a highly amusing paper for you.Original description of Gryposaurus in the Ottawa NaturalistBorealopelta was a fussy eaterThe open access paper describing BorealopeltaGet In TouchEmail: [email protected]Twitter: @TheDinosourceThanks to June "McGreatness" Paik for our lovely podcast artwork....more34minPlay
July 17, 2020015 - Super Sauropods (Nigersaurus and Bajadasaurus)ReferencesSauropod egg sizeSauropod parentingThis is the best source I have on baby sauropods running. All the sources I can find are press releases from late 2010, and I haven’t been able to find any papers which may have come out of this.Paul Sereno on a dig, doing his best Indiana Jones impressionBajadasaurus, the wackiest sauropod of them all?Source on Bajadasaurus size and weight, assuming it is similarly sized to Amargasaurus and DicraeosaurusOkay my reference on the goat eyes thing isn’t the bestPneumaticity of neck vertebrae in dicraeosaurid sauropodsGet In TouchEmail: [email protected]Twitter: @TheDinosourceThanks to June "McGreatness" Paik for our lovely podcast artwork....more38minPlay
July 03, 2020014 - Hell Creek Predators (Tyrannosaurus and Dakotaraptor)ReferencesAn excellent summary of the Hell Creek Formation and the dinosaurs found there by Russel et alHorner et al’s discussion of the prevalence of Tyrannosaurus fossils compared to EdmontosaurusRemember Kosmoceratops? The paper describing that genus also gives evidence of the “dinosaur provincialism” theory postulating separation of dinosaurs in Laramidia into northern and southern “provinces”Something a lot like a Tyrannosaurus was chomping on EdmontosaurusI don’t have a great source on the “T. rex olfactory bulb was smaller than some papers indicate”, but in my defence Dr David Hone (a real paleontologist) said it on a podcast so it has to be rightFarlow’s paper on how T. rex would have died if it ran as fast as depicted in the movieTyrannosaurus was likely too big for feathersIf T. rex did have feathers, it probably didn’t look like this, which makes us sadThe paper introducing Dakotaraptor to the worldThe closely-related-maybe-the-same-dinosaur AcheroraptorWas Dakotaraptor actually just a big Acheroraptor? Andrea Cau has some thoughts!Whoops that bone was actually from a turtle, not a DakotaraptorRoach et al. take on the “hunting in packs” hypothesisGet In TouchEmail: [email protected]Twitter: @TheDinosourceThanks to June "McGreatness" Paik for our lovely podcast artwork....more43minPlay
June 19, 2020013 - Pterosaurs (Pterodactylus and Dimorphodon)ReferencesMark Witton’s excellent book, PterosaursAnurognathids may have had feathers! Don’t quote me on that.Nyctosaurus, one of the fanciest flappy boisThe paper which named "pycnofibres"Pterodactylus kochi with preservation of neck tissue. Source indicates that it is P. scolopaciceps rather than P. kochi. Both of these species have since been moved out of the Pterodactylus genus, and it’s unclear to me to which species and genus this should now be attributed. Comments and clarifications welcome.Pterosaur posture in water, with bonus information on how they would have taken off!Pterodaustra, a much cooler pterosaur than PterodactylusThe confusing history of study of pterosaur locomotionHow Dimorphodon helped us understand how pterosaurs walkedDe La Beche was indeed a slave owner!
