The physiology of dinosaurs has historically been a controversial subject, particularly their thermoregulation.Recently, many new lines of evidence have been brought to bear on dinosaur physiology generally, including not only metabolic systems and thermoregulation, but on respiratory and cardiovascular systems as well.
Gasosaurus (/ ɡ ˈ æ s ə ˈ s ɔːr ə s /) is a genus of tetanuran theropod that lived approximately 171.6 to 161.2 million years ago during the middle of the Jurassic Period.The name "Gasosaurus" is derived from the English "gasoline" and the Greek σαῦρος (sauros) ("lizard / generic reptile").
In 2023, a juvenile Gorgosaurus (TMP 2009.12.14) with its in situ stomach contents containing two Citipes juveniles about a year old intact was reported from the Dinosaur Park Formation. This juvenile would have been 5-7 years old at the time of death, measuring about 4 metres (13 ft) long and weighing around 335 kilograms (739 lb).
Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous in North America. The type specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments and was described as Quetzalcoatlus northropi in 1975 by Douglas Lawson.
“Histamine is released in the body and enters the gastrointestinal tract, which can cause gas, bloating, nausea, stomach pains and diarrhea.” He notes specific foods that can make seasonal ...
While the dinosaurs' modern-day surviving avian lineage (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs (non-avian and avian) were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 m (59 ft) and were the largest land animals of ...
"However, symptoms from an upset stomach will subside within 24 hours at most, which isn't the case for norovirus infections." To recap, ... Stomach pain. Nausea. Vomiting. Diarrhea.
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
