This is how scientists calculate the number of T. Rexes living on Earth.



Tyrannosaurus Rex Probably the most iconic symbol of the dinosaurs that have been immortalized in the movie, The Kids Toys and Silly Halloween Costumes. The “King of Tyrant Lizards” and its sinister appearance make it clear why: The T. rex has a large head, powerful jaws, sharp teeth and a whip-like tail. (Although its flimsy arms are cartoon characters in contrast to the rest of the picture), the T. rex is believed to be one of the largest terrestrial carnivores of all time, measuring over 40 feet long and 12 feet tall at hip

But, like this extinct animal, it is difficult to know how much a threat the T. rex was during its reign. (Especially in recent years, there has been some debate about whether T. Rex is a hunter or a scavenger, although more recently scientific consensus has turned to hunters.) They̵

A group of scientists led by Charles R. Marshall, director of the University of California Museum of Paleontology, issued a response: They believe they can now estimate roughly how many T. Rexes have traveled around the world.

Their forecast is about 2.5 billion samples roaming the world during their lifetime, which spans a few million years. (They would have lived for generations if not for the extinction event, most likely caused by a meteor or comet 66 million years ago.)

The researchers, which published their findings in Science magazine, estimate that T. Rexes were in abundance at any given time, about 20,000, and that they lived approximately 127,000 generations to match the current predator population. That number of 20,000 is equivalent to the current African lion population, estimated by conservationists at 25,000.

Scientists come to estimates using a wide variety of information. For one thing, they take into account a principle called Damuth’s Law, which holds that organisms with larger body sizes tend to have lower average population densities. Because the formula includes lesser species of species, scientists use an approximation for “The person behind the youth” – T-rex is the equivalent of an angry teenager. (Now there is a conscious mind.) Once they have the information, they multiply by the approximate geographic area that paleontologists believe the beast that once roamed. They then included what we know about when T. Rex was alive, although scientists admit that the numbers are not particularly clear. “Due to poor temporal control in most T. rex fossil areas, and because there are many dinosaur conservation gaps below the oldest,” he said. T-Rex fossils “

Because experts believed, based on the fossil evidence, they lived anywhere from 1.2 million to 3.6 million years, the team settled on the 2.4 million year average, and then they plugged the other numbers together until it finally arrived. Estimate

Despite its brief rule on the planet, the Cretaceous-Thyristor extinction event is unfortunately cut short – the fact that other bipedal hunters will. Their census 66 million years later speaks of their cultural immortality.
