Apr 5, 2022 · T. rex’s short arms may have lowered risk of bites during feeding frenzies. A new hypothesis suggests that the T. rex’s short arms may have evolved to avoid injury during communal feeding, particularly to prevent accidental or intentional amputation caused by the creature’s powerful jaws and teeth. Over the two decades paleontologist ...

Some people have suggested that they use their arms for sex.. like to touch the other one.. but we don't really know. Chances are that they may have been tiny because they were not used. Look at chickens and kiwi birds (we know that some dinosaurs related to T. Rex did evolve into birds)... these are flightless birds they have wings but really don't use them. Chickens use t

Specifically, the paper's T. rex was distinguished by robust anatomy, a moderate ratio of femur length vs circumference, and the possession of a singular slender incisiform dentary tooth; T. imperator was considered to be robust with a small femur length to circumference ratio and two of the slender teeth; and T. regina was a gracile form with a high femur ratio and one of the slender teeth.

Tarbosaurus is probably the closest relative of Tyrannosaurusdiscovered so far. The only notable morphological differences between it and Tyrannosaurus are that Tarbosaurus has proportionally smaller front limbs (yes, there are dinosaur species with even smaller arms than T. rex), a proportionally longer and narrower skull (resulting in eye sockets...
There were two types of tyrannosaurids in North America—the northern type (including Albertosaurus, Gorgosaurus, and Daspletosaurus) and the southern type (including Teratophoneusand Lythronax). Tyrannosaurids on the northern part of the continent possessed a ridge on their fourth metatarsal bones (bones that together with tarsi make up the upper f...
Daspletosaurus torosus is most widely accepted as the direct ancestor to Tyrannosaurus rex. The only notable differences between the two are that Daspletosaurus possesses proportionally larger teeth, longer arms, and smaller feet, and is overall more muscular and heavily built than Tyrannosaurus. Its fossils can be found in Alberta and Montana and ...
During the 1990s, a small bone called the lacrimal (a bone separating antorbital fenestra from the eye socket) was found in the Judith River formation in Montana, but it was quickly forgotten. It was found in the circa 75-million-year-old sediments from the late Cretaceous period. Only later, in 2006, would paleontologists Urban and Lamanna finally...

Tyrannosaurus rex is one of the largest and most popular members of the Tyrannosaurus family of dinosaurs.
