    On this episode, we focus on:

    • The dinosaur of the day: Tyrannotitan
    • Title means “Tyrant titan”
    • Bipedal carnivore that lived within the early Cretaceous, in what’s now Argentina
    • Species identify is Tyrannotitan chubutensis
    • Species identify refers back to the Chubut Province, the place the fossils had been discovered
    • Described in 2005 by Fernando Novas, Silvina de Valais, Pat Vickers-Wealthy, and Tom Wealthy
    • Fragmentary cranium and decrease jaw discovered, in addition to enamel and partial put up cranial skeleton
    • Holotype included enamel, again vertebrae, proximal tail vertebrae, ribs, humerus, ulna, almost full femur, fibula, neck vertebrae
    • Carefully associated to Carcharondontosaurus and Giganotosaurus, in addition to Mapusaurus
    • Together with Acrocanthosaurus, it’s the oldest identified large carcharodontosaurid in North America
    • Had small forearms, like a tyrannosaurid, however was not as a result of South America was remoted from North America and Africa on the time Tyrannotitan lived
    • Some scientists suppose that Tyrannotitan may truly be the identical as one other carcharodontosaurid from South America, however for now it’s thought of its personal genus
    • About 40 ft (12.2 m) lengthy, although Gregory Paul estimated in 2010 it was 43 ft or 13 m lengthy
    • Weighed over 6 tons
    • Tyrannotitan is completely different from different carcharodontosaurids due to it’s lack of penumaticity (air areas in bones) within the hip and tail vertebrae, so had no air pockets to assist cut back its weight
    • Tooth weren’t as developed as different carcharodontosaurids (no clear curves to assist with slicing, however form was just like form of Allosaurus enamel)
    • “Chisel-like” denticles on its enamel
    • Tooth had denticles with grooves that divided them (denticles helped to tear into flesh); completely different from different enamel of later dinosaurs with curved enamel with serrated edges (could have been experimental)
    • Tooth had been good from stripping flesh from lifeless prey as an alternative of crunching bones
    • In Could 2014, it was reported that there was a dinosaur graveyard of big titanosaurs, together with over 50 Tyrannotitan enamel, on the La Flecha farm in Patagonia, Argentina
    • Can see Tyrannotitan within the Museum of Paleontology Egidio Fergulio, in Patagonia, Argentina
    • Within the Jurassic World park builder sport, you’ll be able to create a Tyrannotitan
    • Carcharodontosaurids (identify means “shark-toothed lizards) had been carnivorous theropods
    • Ernst Stromer named the household in 1931
    • Household consists of Giganotosaurus, Mapusaurus, Carcharodontosaurus, and Tyrannotitan (all about similar dimension or bigger than T-rex)
    • Carcharodontosaurids and spinosaurids had been the biggest predators in Gondwana within the early and center Cretaceous
    • Enjoyable truth: Our photo voltaic system isn’t at all times in the identical place throughout the Milky Approach, it’s truly orbiting in a short time(?). It’s shifting about 52,000mph or 84,000km/h and it takes about 200MY to make a full orbit. And probably… in response to “Mass Extinction and the Construction of the Milky Approach,” by M.D. Filipovic and others, there could also be a hyperlink between our photo voltaic system passing by way of the spiral arms of the milky means and our mass extinction occasions. Additionally, perhaps not…
