In a paper published in the journal PeerJ, paleontologists present bite force estimates for a juvenile Tyrannosaurus rex based on mechanical tests designed...
Animals display a variety of gaits and walking speeds. It is commonly assumed that they minimize locomotor energy expenditure by selecting gait kinematics...
Paleontologists estimate that the abundance of one of the best-known dinosaurs, Tyrannosaurus rex, at any one time was about 20,000 individuals, that the...
An international team of paleontologists has examined the fossilized remains of baby tyrannosaurid dinosaurs found in Alberta, Canada, and Montana, the...
Non-avian theropod dinosaurs like Tyrannosaurus rex relied less on speed, more on energy-saving, according to a new study published in the journal PLoS...
A new species of tyrannosaurine dinosaur that lived about 79.5 million years ago (Cretaceous period) has been identified from fossils found in Alberta,...
In the early 2000s, the fossilized skeletons of two small tyrannosaurs were collected from the famous Hell Creek Formation of Carter County, Montana. Nicknamed...
Footprints of duck-billed dinosaurs, armored dinosaurs and a tyrannosaur discovered in Aniakchak National Monument, southwestern Alaska, shed new light...
A new species of predatory tyrannosauroid dinosaur that lived about 92 million years ago (Cretaceous period) has been identified from fossils found in...
Paleontologists have unveiled a remarkable new species of tyrannosauroid dinosaur from the Cretaceous period: a small relative of Tyrannosaurus rex. The...
Paleontologists have unveiled a remarkable new species of tyrannosaurine dinosaur from the Late Cretaceous epoch — a cousin of the fearsome predator...
