A new study has cut the number of Tyrannosaurus rex that roamed the earth to just 1.7 billion individuals that lived about 68 million years ago.
The number challenges the 2021 estimate of 2.5 billion individuals.
But it is still a bunch of dinosaur kings.
The question is where are all the fossils went. A tiny number of T. rex fossils have been discovered, likely not even the largest specimens. One November 2022 study estimated that the largest T. Rex was 70 percent larger than Scotty the Saskatchewan skeleton, found in 1991. Scotty was estimated to weight more than 19,000 pounds in life, but a larger T. rex could weight more than 30,000 pounds.
Scientists also now believe that the creature had the same walking speed as humans at about three miles per hour instead of the previous six mile per hour estimate, according to Live Science.
