Some of the competition may have been wiped out by climate change in the Triassic–Jurassic mass extermination.

Around 252 million to 201 millions years ago, approximately 76 percent of all land-based and marine species were extinct from the Earth’s surface. The Triassic-Jurassic mass extinction It is widely believed that this is what allowed dinosaurs to dominate the landscape. However, scientists are still trying to understand how and why. A new study was published in the journal Science Friday. Current BiologyAccording to, it was not competition between species but climate change that allowed them to rise to the top of their food chain.

The sauropod-like dinosaurs, which would become the giant herbivores species seen during the Jurassic. Diplodocus And BrachiosaurusAs the Earth warmed, they grew and prospered to new areas. These dinosaurs are well-known for their ability to massive bodies With long tails and giraffe-like necks, paired with a small head.

A team of paleontologists from Brazil, Germany, and the United Kingdom compared computer models of global climate conditions such as temperature and rainfall with Data on the different locations This period saw the emergence of dinosaurs. Their work demonstrated that both sauropods as well as sauropod-like creatures were winners during this turbulent period of Earth’s history.

The Earth may be warming, and dinosaurs could be ruling it.

“What we see in data suggests that rather than dinosaurs being outcompeted, it was variations climate conditions that were restricting them diversity,” Emma Dunne (study co-author, paleontologist at Friedrich-Alexander University Erlangen-Nurnberg), said. In a statement. “But once the Triassic–Jurassic boundary changed, they were able flourish. These results were surprising because sauropods were very fussy from the beginning. Later in their evolution, they tended to stay in warmer regions and avoid polar areas.

There is still Scientists engage in debate This article explains the causes of this extinction. Scientists believe that climate change and sea level rising are the result of a sudden large release carbon dioxide that occurred during the Supercontinent Pangea began to driftThis is the key to devastating volcanic eruptions. As the Land masses The area now known as eastern North America and northwestern Africa split up, and it is possible that up to 100,000 gigatons carbon dioxide were released into the atmosphere. The greenhouse effect was likely to be exacerbated by this extra carbon dioxide. Temperatures can be increased by up to 18-27 degrees F.

Further research will be conducted to better understand the effects of climate change since the dinosaurs took over.

Richard Butler, a University of Birmingham paleontologist, stated that “what we want to do next” is to use the same techniques to understand climate’s role in the next 120,000,000 years of the dinosaur story. In a statement.
