According to the research, To "grab dinosaur partner" during prehistoric sex sessions, T-tiny rex's arms were used.
Scientists now assume that T-REX males used their little arms to hold their female dinosaur partners while having sex.
A recently discovered, nearly perfect skeleton provides evidence that the muscles supporting the stunted limbs were robust.
It indicates that the arms, which have baffled scientists for decades, did not decrease because they were worthless but rather had a function.
The discovery was made after studying the fossil of a new species called Meraxes gigas, which reached a height of 36 feet.
