The dinosaur of the day: Tsintaosaurus
- Hadrosaurid that lived within the Late Cretaceous in what’s now China (Jingangkou Formation)
- About 27 ft (8.3 m) lengthy and weighed 2.5 tonnes
- Herbivore, had a dental battery and a “duck invoice”
- Principally quadrupedal, however might rear up on two legs when looking out and to run away from predators, or to eat
- Could have lived in herds
- Fossils present in 1950
- Described in 1958 by C. C. Younger (Yang Zhongjian)
- Kind species is Tsintaosaurus spinorhinus
- Identify means “qingdao lizard” (previous transliteration, which is transferring one letter of the alphabet of 1 language to the opposite, of Tsingtao)
- Qingdao is a metropolis
- Species identify means “with a nostril backbone”
- Holotype consists of a partial skeleton with a cranium (paratype discovered, with a cranium roof)
- Usually talked about as a “unicorn-like” dinosaur
- Younger thought Tsintaosaurus had a unicorn-like crest on its cranium (with a fork on the finish), about 15.7 in (40 cm) lengthy and almost vertical from the again of the pinnacle, and that the crest was hole
- Different partial skeletongs and disarticulated parts have been present in the identical space. Some Yang referred to Tsintaosaurus, others have been named Tanius chingkankouensis or Tanius laiyangensis
- Rozhdestvensky and Taquet thought-about Tsintaosaurus spinorhinus to be a junior synonym of Tanius sinensis
- Not everybody agreed
- In 1990, David Weishampel and Jack Horner mentioned the crest was not hole and will have really been a damaged nasal bone from the highest of the snout, and if Tsintaosaurus didn’t have a definite crest, it might have been a synonym of Tanius (which appeared comparable however didn’t have a crest). They thought Tsintaosaurus was a chimera
- Then in 1993 Eric Buffetaut and in 1995 Haiyan Tong-Buffetaut discovered that the crest was appropriate (upright) and described a second specimen with a vertical crest, which helped present the crest was actual, and Tsintaosaurus was distinct due to it
- In 2013 Albert Prieto-Márquez and Jonathan Wagner reconstructed Tsintaosaurus and located the crest was the rear half of a bigger head crest that began on the tip of the snout, and included fused nasal bones that made a hole tubular construction. The crest would have been largely vertical however pointed somewhat to the again of the pinnacle (might have initially appeared vertical due to the way in which it fossilized)
- Crest was hole and domed
- They discovered that the tubular construction was not an air passage and advised it helped make the crest much less heavy
- Nasal passage passes by the crest
- Nasal passages might have allowed Tsintaosaurus to make low-frequency noises
- Fundamental a part of the crest hasn’t been but discovered however would have been product of premaxillary bones
- Additionally discovered that Tsintaosaurus had a number of distinct traits, together with a spherical, thick rim of is higher beak
- Categorised as a lambeosaurine

Enjoyable Truth:
Dwelling dinosaurs (birds) are the one amniotes with coloured eggs. They most likely developed in Archosauria, presumably inside Eumaniraptora.
