On this episode, we talk about:
Information:
- Three exceptionally properly preserved new sauropodomorphs in Brazil have been used to explain the brand new genus Macrocollum (actually “lengthy neck”) supply
- One other new opalized dinosaur fossil was present in Australia, this one was from a jaw and named a brand new genus—Weewarrasaurus supply
- Seven vertebrae from the banks of the Volga river have been used to explain the brand new titanosaur Volgatitan supply
- Histology on a fossil from northeastern China seems to indicate that enantiornithine dinosaurs had medullary bone supply
- A bunch of dinosaur footprints have been present in Zhaojue county, Sichuan Province, China, at a copper mine supply
- Zuul went on show on December 15 on the Royal Ontario Museum; A number of occasions are deliberate round its unveiling supply
- The brand new Subject Museum Mesozoic murals drew loads of ire for copying paleoartists’ work with out permission supply
- The Pure Historical past Museum in London and the Smithsonian are working to digitize all of the fossils of their collections supply
- Disney Channel has a brand new dinosaur present, known as Gigantosaurus (to not be confused with the precise dinosaur Giganotosaurus) supply
- The Australia Zoo put in a brand new life-sized Triceratops supply
The dinosaur of the day: Wuerhosaurus
- Stegosaurid that lived within the Early Cretaceous in what’s now China and Mongolia
- One of many final stegosaurs (most stegosaurs have been from the Jurassic interval)
- Present in Xinjiang, in western China, the Tugulu Group
- Fossils present in three localities
- Described in 1973 by Dong Zhiming
- Sort species is Wuerhosaurus homheni
- Identify means “Wuerho lizard”
- Identify Wuerhosaurus refers back to the metropolis of Wuerho
- Holotype consists of a largely full pelvis, vertebrae, humerus and phalanx, and two dermal plates; paratype consists of some tail vertebrae
- In 1988 a smaller stegosaur was present in Interior Mongolia, Ejinhoro Formation, and described in 1993 by Dong
- Named Wuerhosaurus ordosensis
- Holotype of second species features a practically full torso, vertebrae, and a whole sacrum with a proper ilium
- Additionally a dorsal vertebra and dermal plate have been referred to the species when it was named
- One other species, Wuerhosaurus mongoliensis was described in 2014 by Ulansky, based mostly on vertebrae and pelvic materials, however that’s now thought of to be a nomen nudum
- Wuerhosaurus homheni most likely had a broad physique, broad stomach
- Estimated to be 23 ft (7 m) lengthy and weigh 4 tonnes
- Dorsal plates have been initially considered both rounder or flatter than dorsal plates of different stegosaurids, however later Maidment stated it solely appeared that means as a result of they have been damaged, and the way they really appeared is unknown
- Had tall nerual spines on the bottom of the tail
- Wuerhosaurus ordosensis additionally had a broad pelvis, but in addition shorter neural spines and an extended neck
- Estimated to be 16 ft (5 m) lengthy and weigh 1.2 tonnes
- Herbivorous, and possibly ate low-growing vegetation
- Most likely stored its head low to the bottom
- Most likely had a thagomizer on the finish of the tail (spikes)
- One spike was discovered, however Dong thought it was on the shoulder
- Had large hips, could have had a bigger digestive space
- Some debate over the place Wuerhosaurus sits within the phylogenetic tree, nevertheless Maidment in 2017 stated Wuerhosaurus was most intently associated to Stegosaurus
- In 2008 Susannah Maidment and others steered Wuerhosaurus was a junior synonym of Stegosaurus, and that Wuerhosaurus homheni must be Stegosaurus homheni (as a result of the holotype was just like Stegosaurus) and Wuerhosaurus ordosensis was doubtful (as a result of the holotype couldn’t be discovered and the outline didn’t point out any legitimate diagnostic traits). Nonetheless, Carpenter disagreed with this in 2010, and steered Wuerhosaurus had sufficient distinct options and was separate from Stegosaurus
- If Wuerhosaurus and Stegosaurus have been synonymous, that might imply Stegosaurus lived from the Late Jurassic to the Early Cretaceous
Enjoyable Truth:
Genus names must be distinctive for each animal, however they are often the identical as a plant identify. So we will by no means identify one other animal Tyrannosaurus, however somebody may identify a flower Tyrannosaurus.
