According to the Daily Mail, researchers recently revealed that a study showed that a small finches weighing only twenty or thirty grams had a strong jaw power than the powerful Tyrannosaurus rex.
Researchers have found 33 grams of finches weighing 33 grams in the Galapagos Islands, and their bite force is 320 times that of T. rex.
The large Galapagos finches found in the Galapagos Islands are only 6 inches long (about 15 centimeters), about the size of the teeth of a Tyrannosaurus rex, but its thick beak emits 16 pounds of force to bite nuts and seeds.
In pound terms, the Galapagos large ground finches had 320 times more bites than Tyrannosaurus rex.
The Galapagos large ground finches long, about the size of a Tyrannosaurus rex's teeth, but its bite force was 320 times that of its eight-ton ancestor.
The scientists analyzed bites from 434 species of live and dead finches, the largest of all in its class.
Its thick beak has an impressive 16 pounds of strength, enough to open nuts and crush seeds.
Dr Chris Venti said: "If the size is the same, then the king of the dinosaurs is definitely not the opponent of the ground sparrow."
Dr Chris Venti of the University of Reading, one of the study authors, said: "If they were the same size, then the so-called 'king of dinosaurs' could not match it."
