The dinosaur of the day: Haya
- Neornithischian (“hypsilophodontid”) that lived within the Late Cretaceous in what’s now the Gobi Desert in Mongolia (Javkhlant Formation and Nemegt Formation)
- Had a considerably lengthy physique, lengthy tail, quick arms, walked on two legs, and had an elongate cranium with a beak
- Had a number of distinctive options, together with 5 “bulbous, unserrated premaxillary enamel”
- The frontals, on the high of the pinnacle “type a remarkably flat and intensive cranium desk”
- Had comparatively huge, triangular nasals
- Had an elongate decrease jaw (dentary) that “types over half the size of the mandible”
- Had quick neural arches
- Had a gracile humerus (arm), that in a single specimen discovered “bears proof of scavenging” (two holes most likely from burrowing arthropods, as seen in different dinosaurs from the Gobi Desert)
- Described by Peter Makovicky and others in 2011
- Discovered a number of specimens that had been well-preserved
- Fossils discovered between 2002 and 2007 by the joint Mongolian Academy of Sciences—AMNH expeditions
- Holotype is an entire, “barely distorted” cranium, and has elements of the backbone
- Kind species is Haya griva
- Genus and species title are “from the Sanskrit for the Hindu deity Hayagriva, an avatar of Vishnu characterised by a horse head, in reference to the elongate and faintly horse-like cranium of this dinosaur, and the frequent depiction of this deity within the Buddhist artwork of Mongolia”
- Title refers back to the lengthy, horse-like cranium
- A lot of specimens discovered, so we all know just about how the entire skeleton seemed
- Just a few specimens had been discovered with quite a lot of gastroliths
- One was described as a “sizeable gastrolith mass” and is simply the second present in ornithopods
- The specimen with the gastroliths discovered close to the stomach had “two tightly clustered lots of pebbles”, most likely quartz or flint
- Mark Norell and Daniel Barta revealed in 2016 a couple of new Haya specimen discovered within the Nemegt Formation
- Fossils discovered round 1992, a fragmentary skeleton that included the left aspect of the pinnacle, elements of the arm, vertebrae, ribs
- A lot of the specimen was eroded however after getting ready the fossils they discovered it had quite a lot of similarities to Haya
- In 2021, Barta and Norell revealed in-depth the osteology of Haya griva (skeleton)
- A lot of referred specimens (counted 36 within the paper)
- Sufficient to see a progress sequence
- Specimens studied had a spread of sizes however histology exhibits they’re perinatal to subadults, and there are not any skeletally mature specimens
- Based mostly on histology, most likely had a excessive progress charge, and all of the specimens sampled appeared to have been actively rising after they died
- Bought extra enamel because it grew
- Gastroliths discovered with a number of specimens
- Gastroliths are easy with rounded edges
- One specimen discovered had cranium and bones “pretty broadly separated from each other, presumably dispersed by scavengers or operating water”
- In a single case, two people had been discovered buried shut to one another, together with a troodontid tooth
- A lot of the bones have holes, most likely from bugs consuming the bones after the dinosaurs died (see in a lot of dinosaurs from the Gobi Desert)
- Different animals that lived across the similar time and place embody the neoceratopsian Yamaceratops, small maniraptorans, mammals, and lizards
