    On this episode, we talk about:

    • The dinosaur of the day: Tethyshadros
    • The genus title is after Tethys, an ocean that was within the Alpine-Himalayan orogenic belt, and the truth that it’s a hadrosauroid
    • Kind species is Tethyshadros insularis
    • “insularis” means insular or “of the island”, on the time Tethyshadros lived it lived on the Adriatic-Dinaric Island, a big island of the European Archipelago
    • Described in 2009 by Fabio Marco Dalla Vecchia, an Italian paleontologist
    • The positioning the place Tethyshadros was discovered was found within the 80s by Alceo Tarlao en Giorgio Rimoli
    • A pupil named Tiziana Brazzatti discovered hand bones within the space in 1994
    • An organization referred to as Stoneage, which offers with fossils, received a fee to excavate fossils, they usually needed to take away greater than 300 tons of rock. Dalla Vecchia helped information the mission. “Antonio” was taken out of the quarry in 1999, barely broken
    • 6 different Tethyshadros specimens had been discovered, although one fell aside throughout excavation and one other one there have been solely forelimbs discovered
    • Tethyshadros is a hadrosauroid that lived in what’s now Italy
    • Paper by Fabio M. Dalla Vecchia within the Journal of Vertebrate Paleontology in 2009: Tethyshadros insularis, a New Hadrosauroid Dinosaur (Ornithischia) from the Higher Cretaceous of Italy
    • The holotype is of a largely full skeleton, nicknamed “Antonio”
    • The holotype is without doubt one of the most full dinosaur skeletons discovered. “The specimen is essentially the most full skeleton amongst medium to large-sized dinosaurs present in Europe for the reason that 1878 discovery of Iguanodon and Dollodon at Bernissart, Belgium,” in keeping with the paper
    • The holotype was about 5-6 years previous
    • Has a mixture of derived and primitive options
    • About 13 ft (4 m) lengthy and weighed 770 lb (350 kg)
    • Massive, elongated cranium
    • Quick neck and tail, lengthy legs
    • Presumably a quick runner, based mostly on lengthy legs and fewer toes
    • Dalla Vecchia stated it’s small due to “insular dwarfism”
    • Insular dwarfism is when animals are on an island and have restricted assets, so that they develop into smaller over time
    • Dalla Vecchia stated that basal hadrosauroids had been in all probability island-hopping from Asia, which is how Tethyshadros ended up on an island in Europe (doesn’t suppose it comes from European or American hadrosaurs
    • Over time, sea ranges might have modified and lands moved round, making it attainable to island hop
    • Had a serrated, snowplow formed beak (not a duck like beak, as hadrosaurs are recognized for)
    • Tethys ocean lined most of southern Europe
    • Higher beak was pointed
    • Unclear why the beak seemed the way in which it did, may very well be for show, grooming, biting sure sorts of vegetation
    • The fossils are on the Civico Museo di Storia Naturale di Trieste
    • Can see an animation of Antonio at
    • Hadrosauroidea is a superfamily of “duck billed” dinosaurs (hadrosaurids) and dinosaurs extra carefully associated to them than Iguanodon
    • Enjoyable reality: Timber down (gliding to flapping) vs, floor up debate (flapping to stand up timber “WAIR” into flying) continues to be hotly contested. In contrast to child birds which use WAIR, early theropods had claws which in all probability would have been a greater strategy to climb than flapping proto-wings. So it’s nonetheless unclear precisely how flight developed.
