Ottawa: A new study has found that the king of the dinosaurs, Tyrannosaurus rex, also known as T rex, probably weighed 15,000 kilograms. This weight is 70% more than the previous estimate.
Researchers at the Canadian Museum of Nature in Ottawa, Canada, created a model that predicted the dinosaur’s largest possible size.
According to an estimate, there were two and a half billion dinosaurs on earth, of which only 32 large T-Rex have been discovered.
The largest among them is T-rex ‘Scotty’ which weighed over 8800 kg and was over 13 meters long. This dinosaur lived in the western region of present-day North America between 6.8 and 6.6 million years ago.
However, the researchers say that the T. rex structures that have been discovered are likely not an accurate representation of the species, and that the structures that have not been discovered may be much larger.
In the study, paleontologists Jordan Mellon and Dr. Dave Hoon first collected data on the population and average age of T. rex.
These researchers used this data to build two models that estimated T. rex’s normal growth throughout its life.

One of these models revealed sexual dimorphism in the size of T. rex, whereby males and females gained weight differently, while others did not.
Dr. Mellon said that if T. rex was dimorphic, it would have weighed more than 24,000 kilograms, but the researchers rejected this model because if it were true, it would have found structures far larger than the existing structures.
In a tweet on Twitter, Dr. Mellon cautioned about the final version of his research, saying that the results of the study would be considered hypothetical until a structure of this size was discovered.
He said in the tweet that it is mechanically possible for this animal to weigh up to 15,000 kg, but for this, a better test will be required.
