On this episode, we talk about:

Information:

• The brand new sauropod Itapeuasaurus was discovered on a seaside in northern Brazil supply
• Fushanosaurus was named from northwest China based mostly on a single huge femur supply
• Jardin d’Acclimation in Paris, France was lined in dinosaur projections supply
• Two Canadian boys welcomed their grandma on the airport whereas all three dressed up as T. rex supply
• Dinosaur World is coming to Cerritos, California on March 8 supply

The dinosaur of the day: Hypsibema

• Hadrosauroid that lived within the Late Cretaceous in what’s now North Carolina and Missouri, within the US
• Herbivorous
• Estimated to have round 1,000 small tooth
• Enamel have been extra serrated than different hadrosaurs, so could have eaten robust vegetation
• In all probability had a beak
• Two species: Hypsibema crassicauda and Hypsibema missouriensis
• Hypsibema crassidicauda estimated to be 49 ft (15 m) lengthy
• Hypsibema missouriensis was barely smaller than Hypsibema crassicauda
• Estimated to be 14 tons, although some estimates put it at 17-20 tons
• Fairly massive, may have been good protection in opposition to predators
• Sort species: Hypsibema crassicauda
• Described in 1869 by Edward Cope, present in Sampson County, North Carolina
• Genus title means “excessive step”
• Cope thought it walked on its toes
• Species title means “with a fats tail”
• A number of specimens discovered, although femur fragments regarded as a part of the syntype have been later discovered to return from a tyrannosauroid just like Dryptosaurus
• Hypsibema missouriensis fossils first present in 1942, on the Chronister Dinosaur Web site, close to Glen Allen, Missouri (first dinosaur fossils discovered within the state, and the one ones discovered to date)
• Holotype of Hypsibema crassidicauda discovered on the King James marl pits in North Carolina (caudal vertebra, humerus, tibia, metatarsal)
• In all probability lived close to a big physique of water
• The Chronister household first found Hypsibema missouriensis when digging a nicely (which they didn’t use as a result of there ended up not being sufficient water)
• Described in 1945 by Charles Whitney Gilmore and Dan R. Stewart
• Stewart collected the fossils, and was nicknamed Dinosaur Dan
• Stewart informed the Smithsonian concerning the discover, who paid $50 for the bones (13 vertebrae from the tail). That cash was used to purchase a cow later. Extra fossils have been later discovered
• Initially regarded as a sauropod, as a result of Gilmore thought it was both a hadrosaur or sauropod, after which determined it couldn’t be a hadrosaur due to the chevrons and the “extra elongate centra”; then a number of many years later excavations began once more on the web site. Geologist Bruce Stinchcomb bought the property, and within the late Nineteen Eighties there have been take a look at excavations. Additionally discovered fish, turtles, vegetation, and tooth from a tyrannosauroidea dinosaur, in addition to elements of the jaw and dental stays of Hybsiema missouriensis
• Initially known as Neosaurus missouriensis, then renamed later in 1945 by Gilmore and Stewart to Parrosaurus missouriensis as a result of the title Neosaurus was already the title for a synapsid
• Donald Baird and Jack Horner in 1979 discovered that Parrosaurus was a species of Hypsibema, named Hypsibema missouriensis
• Some thought Hypsibema missouriensis was doubtful, and no less than one scientist thinks Parrosaurus is a legitimate genus, and separate from Hypsibema (based mostly on newer discoveries on the web site the place the holotype was discovered)
• Missouri state soil just isn’t nice for preserving fossils. Man Darrough, a paleontologist from St. Louis siad it was “just about a miracle” that dinosaurs have been discovered there
• Hypsibema missouriensis is the official state dinosaur of Missouri, as of 2004
• Missouri was the sixth state within the US to have an official dinosaur (virtually unanimous approval)
• Some Hypsibema missouriensis fossils are housed on the Smithsonian in Washington, D.C.
• Can see a full sized mannequin of the dinosaur on the Bollinger County Museum of Pure Historical past in Missouri (the museum says having the official state dinosaur has tripled the variety of guests)

Enjoyable Reality:
There are about 22 titanosauriform sauropods which have been present in China up to now. However solely 3 have a Chinese language title that matches the official Latinized title.
