New dinosaur species ‘reveals’ climate change 100 million years ago

One new species of herbivorous dinosaurs was discovered in Jute and sheds light on major environmental changes that took place in North America about 100 million years ago. Dinosaur name Jan Smith.

This dinosaur may be one of the last of its kind at the time Earth’s warmer climate has caused massive changes in dinosaur populations World. The transition period between the Early and Late Cretaceous saw a major reorganization of global ecosystems associated with a peak in global temperatures. The increase in carbon dioxide in the atmosphere led to higher temperatures and rising sea levels, causing the dinosaurs to concentrate in smaller and smaller areas.

The fossils were found in the Cedar Mountain Formation in Utah and include Mr.but the skull and parts of the spine and limbs are preserved. The name given to the dinosaur comes from their god. Roman Janoswho was the god of transitions, and thus the dinosaur’s name refers to the changing world of the mid-Cretaceous period.

It is the first early ornithopod known from the Late Cretaceous of North America. Ornithopod dinosaurs are a group of mostly bipedal herbivores, including iguanodons, parasaurolophus, and tenontosaurus.

“We knew this species was in this ecosystem because individual teeth were collected, but we didn’t expect to see that many.” beautiful frame, especially from this point in Earth’s history. Having a near-complete skull was invaluable for compiling history,” says Lindsey Zano, associate professor at North Carolina State University, head of paleontology at the North Carolina Museum of Natural Sciences and author of the study. The study was published in the open access journal Plos One..

This discovery, along with other recent reports from the same geological formation, shows that several large groups of dinosaurs survived into the early Late Cretaceous despite environmental changes at the time, but it is not clear how long they survived. Of course, this particular dinosaur belongs to the early rhabdomorphs, a line of ornithopods known almost exclusively from Europe, and that raises questions.
