What was the population of T Rex?
Marshall is quick to point out that the uncertainties in the estimates are large. While the population of T. rexes was most likely 20,000 adults at any give time, the 95\% confidence range — the population range within which there’s a 95\% chance that the real number lies — is from 1,300 to 328,000 individuals.
How many Tyrannosaurus rexes were there in North America?
Billions. Over approximately 2.5 million years, North America likely hosted 2.5 billion Tyrannosaurus rexes, a minuscule proportion of which have been dug up and studied by paleontologists, according to a UC Berkeley study. (Image by Julius Csotonyi, courtesy of Science magazine)
How big was the population of dinosaurs?
There are around a thousand different genera of dinosaurs known. We can’t directly measure the size of populations because we don’t know what percentage of individuals are preserved in the fossil record. Twenty million bison roamed America in the 18th Century and dinosaurs, being egg layers, could have reproduced faster.
Where was the largest Tyrannosaurus ever found?
In the summer of 2000, Jack Horner discovered five Tyrannosaurus skeletons near the Fort Peck Reservoir in Montana. One of the specimens was reported to be perhaps the largest Tyrannosaurus ever found.
