The dinosaur of the day: Zhuchengtyrannus
- Tyrannosaurid theropod that lived within the Late Cretaceous in what’s now Shandong Province, China (Xingezhuang Formation)
- Appeared just like Tyrannosaurus, and had highly effective jaws, and small arms with two-fingers on its fingers
- Massive and carnivorous
- Estimated to weigh as much as 6 quick tons
- Kind and solely species is Zhuchengtyrannus magnus
- Described and named in 2011 by David Hone and others
- Genus identify means “Zhucheng tyrant”
- Genus identify refers back to the kind locality (Zhucheng Metropolis)
- Species identify means “nice” in Latin (due to it being so giant)
- Dave Hone wrote on his weblog he’s not keen on “place-name-saurus” kind names, and he wrote: “a few of us are born with dangerous names for dinosaurs, some obtain dangerous dinosaur names, and (on this case) some have dangerous names thrust upon them!”)
- Fossils present in 2009, whereas a building crew was digging foundations for a museum
- Holotype is ZCDM V0031, and features a practically full proper maxilla (higher jaw) and left dentary (the decrease jaw). Each have enamel
- Now housed at Zhucheng Dinosaur Museum
- Solid on the Institute of Vertebrate Paleontology and Paleoanthropology
- Maxilla was later broken throughout dealing with, however the solid was made and it was photographed earlier than the accident
- No damaged bones or indicators of pathologies
- In all probability an grownup, or close to grownup, primarily based on its measurement and traits seen solely in grownup tyrannosaurs, corresponding to heavy sculpting on the maxilla
- Maxilla was 25 in (64 cm) lengthy, and dentary was about 31 in (78 cm) lengthy
- Two grownup T. rex specimens have maxilla are 1 and a pair of cm longer, and Sue the T. rex has a 79 cm lengthy maxilla
- Tarbosaurus specimens vary from 19 in (49 cm) (in all probability a juvenile) to 29ish in (73 cm) lengthy, with a number of within the low 20s in inches (60s in centimeters)
- Laborious to know precise measurement of Zhuchengtyrannus
- Dentary of the holotype is a bit smaller than most T. rex specimens, and a bit larger than most Tarbosaurus specimens
- Based mostly on maxilla, holotype is about the identical measurement as or in between Tyrannosaurus and Tarbosaurus
- So Zhuchengtyrannus estimated it to be between 33–39 ft (10–12 m) lengthy
- Had distinctive options in its cranium
- Delicate options in how the fenestrae, fossa, and different elements of the cranium are organized. Close to the entrance of the fenestra on the maxilla there’s a rounded notch, and there’s a horizontal shelf on the lateral floor of the bottom of the ascending technique of the maxilla (the half going up from the higher jaw)
- Hone additionally stated there are in all probability a variety of Zhuchengtyrannus fossils collected, however they have been remoted and to date, it’s too arduous to tell apart it from the opposite tyrannosaur (thought be completely different due to the enamel), so for now may solely level to the 2 cranium items discovered collectively
- A second dentary and a second maxilla discovered on the identical website, Zangjiazhuang quarry (completely different from Zhuchengtyrannus, which implies there may be in all probability no less than one different tyrannosaurid from the realm, although not but named)
- Tooth have serrations that go all the way in which to the bottom of the tooth crown
- Dave Hone wrote on his weblog across the time of publication, “Whereas 2010 was celebrated because the 12 months of ceratopsians for a lot of, it shouldn’t be neglected the massive variety of tyrannosaurs which have cropped up within the final 12 months or so”
- Second tyrannosaurine from China, and possibly overlapped with Tarbosaurus (no direct proof however fossils discovered close to one another, in time and house)
- Phylogenetic evaluation in 2013 discovered Zhuchengtyrannus to be the sister taxon of Tarbosaurus (each tyrannosaurines), and instructed Zhuchengtyrannus and different identified tyrannosaurids in Asia have been a part of an evolutionary radiation (fast improve in a clade’s variety) that got here from the identical North American stem that led to Tyrannosaurus
- Appears to be a pattern of a number of species of enormous, carnivorous dinosaurs residing on the identical time and place. In all probability stuffed completely different ecological niches
- In all probability was a predator and scavenger
- Having so many giant carnivores round one another might have been extra of the norm (like Spinosaurus and the Kem Kem Beds), so it’s uncommon that doesn’t appear to be the case for T. rex
- Fossils present in what was once a floodplain (dinosaurs in all probability washed collectively throughout floods after which fossilized)
- Present in one of many highest concentrations of dinosaur fossils on the planet
- Additionally from the identical time and place: Sinoceratops, hadrosaurids (in all probability Shantungosaurus) and ankylosaurs
Enjoyable Reality:
Spinosaurus wasn’t the one dinosaur fossil destroyed throughout World Battle II, there have been no less than 5 others.
