Dinosaur Fossils in Antarctica

Fossils of dinosaurs gathered in Antarctica millions of years ago and became a super continent called Pangea. As time passed, the plates beneath the earth began to separate and the land of the continent moved towards the pole where the glacier was working. The Ice Age is a process of glaciers formed during the ice ages. Glaciers cause a decline in temperature, which causes water to freeze and form multilayers of ice (http://palaeo.gly.bris.ac.uk/Palaeofiles/Permian/intro.html,1).

Since 1897, the search for dinosaur fossils has been expanded to include continents including Antarctica. In 1986, Antarctopelta oliveroi, the first Antarctic dinosaur discovered in 1986, was found in James Roth Island, which was a South Pole species before 1994, but was officially named Cryolophosaurus ellioti. And it is described in scientific journals. The current dinosaur's "hot spot" includes southern South America (especially Argentina) and China. Due to the unique geological features of the dinosaur bed and the ancient dry climate that particularly contributes to petrochemicals, China has created many special wing dinosaur specimens.

Dinosaur fossils were discovered in regions close to the polar region at relevant times, especially in the northern slope of southeast Australia, Antarctica and Alaska. There is no evidence that the angle of the earth's axis has changed significantly, so extreme dinosaurs and other ecosystems need to respond to the same extreme changes as today (summer will not go dark all day, winter will not be sunny) . All day)

Considering that isotherms are not usually seen in high latitude areas (the weather is very cold). Assumption: Since dinosaur fossils are well known at high latitudes, they must be endothermic to deal with the cold. Problem: The high latitude dinosaur fossils (Alaska, Antarctica etc.) turned out to be not as cold in the Mesozoic; in fact, they may be nearly subtropical. Even if they are a bit cold, dinosaurs will move there during the warm summer and cool down in the cold winter. Also, the climate of the Mesozoic is usually warmer and more calmer than today (I just remembered from the last glacial age, I remember it). Finally, today's snakes, lizards, sea turtles, large lizards and crocodiles enjoy a surprisingly wide latitude distribution. However, many dinosaur remnants were discovered in the UCMP site work on the north slope of Alaska. In the late Cretaceous days when these dinosaurs lived, the area became very seasonal.
