1.7 Billion Trex Lived on the Earth?

Tyrannosaurus Rex: The king of dinosaurs that roamed the Earth

Dinosaurs are one of the most mysterious creatures on the Earth, and Tyrannosaurus Rex is one of the most famous. According to a new paper, about 1.7 billion Tyrannosaurs once roamed the Earth. But it doesn’t mean that all Tyrannosaurs lived in same period. The paper estimates that only 19,200 are alive at higgest fastigium. This article will explore some basic information about T-Rex and the implications of these new studies for our understanding of T-Rex populations.

Basic information about Tyrannosaurus Rex

Tyrannosaurus Rex, a dinosaur that lived 145 million years ago during the Late Cretaceous period, was a giant carnivorous predator. It was one of the largest land predators known, possibly 40 feet long, 12 feet tall and weighing up to 15,000 pounds. It has strong hind legs and can run and chase its prey. Its teeth are sharp and powerful, and can easily bite through the skin and bones of its prey. Tyrannosaurus rex was a formidable force during its lifetime, capable of eating prey the size of a school bus with teeth the size of a forearm.

The number of Tyrannosaurus Rex

Several studies have estimated the number of Tyrannosaurus Rex. A recent study estimated that there were about 1.7 billion Tyrannosaurs on Earth. However, the models of these studies all rely on certain variables and assumptions, such as the number of known Tyrannosaurus Rex fossils, the oldest Tyrannosaurus rex ever found, and the onset of sexual maturity. In addition, they all asked the authors to estimate in some way the life expectancy of newborn T-Rex and the reproductive rate of adult T-Rex.

New research

However, an evolutionary ecologist, Eva Griebeler, has published a new paper that revises the previous research. She modeled the reproductive rate of T-Rex based on that of other spawning species, reptiles, and birds, and reduced the all-important life expectancy figure for newborn T-Rex to a level more in line with that of living species. As a result, she estimates that 1.7 billion Tyrannosaurs have lived for 96,800 generations, meaning that dinosaurs have been on the Earth for 2.03 million years, which is exactly in line with previous estimates.

Remarkably, of the estimated 1.7 billion Tyrannosaurs alive, scientists have recovered only a small fraction – 32 comparatively integrated fossils discovered. So, raising new questions that other enormous amount bones disintegrated? When minerals from the surrounding sediment seep into the bones and prevent them from breaking down, enormous amount bones should existed to today.

Conclusion

Tyrannosaurus Rex is one of the most mysterious creatures on the Earth and one of the most famous dinosaurs. While we still have a lot of questions about how many of it there is, new research gives people a more accurate estimate. Paleontologists will continue to study these prehistoric creatures to better understand the Earth’s history and evolution.

Question for us:

1. Why you bring real Tyrannosaurus Rex back to the earth.

2. How long you build vivid dinosaurs? What species of Tyrannosaurs you’ve made?

Answers for our fans:

1. We just use silicone, steel…raw materials to build robotic dinosaur (animatronic dinosaur). Each dinosaur model we made owns natural size and motions.

2. Basically, we can make any Tyrannosaurs species in model, open link as https://animatronicanimal.com/tag/tyrannosaurus-rex-model/, you would find species you like! But, we don’t have made all species.
