The scholars considered that the average age of a specimen of this animal at the time it reaches sexual maturity is 15.5 years, with a lifespan of between 25 and 30 years.
HOW MANY YEARS DO DINOSAURS LIVE ACCORDING TO THEIR PERIOD
The Mesozoic is divided into three huge periods: Triassic, Jurassic and Cretaceous. One of the considerable differences between periods is time, which shows the evolution of many dinosaur species and the extinctions in between these periods.
The Triassic period began 250 million years ago and ended 201 million years ago. This period was characterized by very dry and hot weather. Earth’s plates were quite close together, which reduced the oceans’ current ability to moderate the temperature.
How many years did a Tyrannosaurus Rex live?
To understand how many years dinosaurs lived, it’s essential to understand that only some of the species had exactly the same longevity. In the same way with the dog groups (some live much longer than others), the same thing happened with the dinosaurs due to the fact that, depending on their body, their vitality and their state, they could live much longer.
North America had 20,000 T. rex at the time
Through study of the fossil record, consistency data, and climate model data, the College of California at Berkeley staff calculated that there were probably about 20,000 older T. rex living in North America and living in a particular instant. That, explained the scholars of a study published in the Science magazine, means that around 2.5 billion predators lived and died during the precisely 2.5 million years that the dinosaurs lived.
For the first time, the team also calculated the longevity of the dinosaur. Using scientific literature and specialist opinion, they estimated that the possible age of sexual maturity for a T. rex was 15.5 years, and that its lifespan could be as long as 20 years. The average body mass of an adult dinosaur was about 5,200 kilos, and by growing to sexual maturity it can reach 7,000 kilos.
what did dinosaurs eat
There were three genera of dinosaurs, classified according to their nutrition:
- grass, apart from a wide variety of plants, leaves, shoots, fruits and leaves; Likewise, they obtained a wide variety of nutrients without needing to be predators of other species, such as carnivores.
- Carnivorous dinosaurs: apart from feeding on other species, fish, mammals, and insects also entered their food chain.
- Omnivorous dinosaurs: they fed on mammals, insects and other dinosaurs, apart from plants and fruits.
How old were the dinosaurs?
To find out how old dinosaurs were and how fast a Tyrannosaurus rex grew, paleontologist Mark Norell and colleagues at the American Museum of Natural History counted the rings on certain dinosaur bones so that by the number of them he could tell precisely what age could dinosaurs achieve.
