There have been billions of T. rexes on Earth over the 2.5 million years dinosaurs lived on our planet.
The issue lies in the number of available fossils. Marshall and his team fed the numbers into computer simulations to minimize the huge variation in figures. And as Marshall pointed out,"Ecological differences result in large variations in population densities for animals with the same physiology and ecological niche.
As Marshall said,"In some ways, this has been a paleontological exercise in how much we can know, and how we go about knowing it.", and other dinosaurs, keep increasing as more fossils get discovered, and the technology to study them improves. "Our knowledge of T. rex has expanded so greatly in the past few decades thanks to more fossils, more ways of analyzing them, and better ways of integrating information over the multiple fossils known."
