Latest Theropoda Stories
Before her death in December 2010, Nieves López Martínez, palaeontologist of the Complutense University of Madrid, was working on the research of dinosaur eggs with a very peculiar characteristic: an ovoid, asymmetrical shape.
Paleontologists have discovered a group of more than 20 polar dinosaur tracks on the coast of Victoria, Australia, offering a rare glimpse into animal behavior during the last period of pronounced global warming, about 105 million years ago.
An international team of paleontologists has unearthed a new species of dinosaur in Inner Mongolia, China.
Scientists have unveiled fossils of one of the earliest dinosaurs ever discovered -- a petite, nimble carnivore from the late Triassic period some 230 million years ago.
While dinosaurs such as the Tyrannosaurus rex have long been assumed to be carnivorous, many of them were, in fact, vegetarians.
The flightless ostrich uses its wings very effectively in high-performance running and may provide valuable information about how its dinosaur ancestors moved.
A new study published in the Proceedings of the National Academy of Sciences provides yet more evidence that birds did not descend from ground-dwelling theropod dinosaurs, experts say, and continues to challenge decades of accepted theories about the evolution of flight.
Through an expedition to the Gobi Desert of China, scientists have solved the puzzle of how one group of dinosaurs came to look like birds--independent of birds.
A team of paleontologists has unearthed a previously unknown meat-eating dinosaur from a fossil bone bed in northern New Mexico.
Fossil experts say the stunning remains of a "four-winged" dinosaur have confirmed that birds owe their ancestry to two-footed dinosaurs that lived millions of years ago.
Velociraptor, meaning “swift seizer” is a genus of dromaeosaurid theropod dinosaur that lived about 75 to 71 million years ago during the later part of the Cretaceous Period. There are two species that are presently recognized. The type species is V. mongoliensis; fossils of this particular species have been uncovered in Mongolia. A second species, V. osmolskae, it was named in 2008 for some skull material from Inner Mongolia, China. They are smaller than other dromaeosaurids such as...
Tarbosaurus, meaning “alarming lizard” is a genus of tyrannosaurid theropod dinosaur that thrived in Asia about 70 million years ago, at the end of the Late Cretaceous Period. Fossils have been uncovered in Mongolia, with more incomplete remains found further afield in parts of China. Many species have been named, although, modern paleontologists recognize only one, T. bataar, as legitimate. Like most tyrannosaurus, Tarbosaurus was a sizeable bipedal predator, weighing up to six...
Spinosaurus, meaning “Spine lizard,” is a genus of theropod dinosaur from the lower Albian to lower Cenomanian stages of the Mid Cretaceous Period (112 to 97 million years ago). It lived in what is now North Africa. The type species is S. aegyptiacus. A potential second species, S. maroccanus, was discovered in Morocco. It was the first known dinosaur fossil from Egyptian remains discovered in 1912 and described by German paleontologist Ernst Stromer in 1915. The original remains were...
Sinosauropteryx, meaning “Chinese reptilian wing,” is a genus of theropod dinosaur from the Late Jurassic to the Early Cretaceous Period 135 to 121 million years ago. It was discovered in 1996 by two Chinese farmers in the dry countryside near Liaoning Province, China. The same area has also produced later on other bird-like dinosaur fossils including Caudipteryx and Protarchaeopteryx. Three complete skeletons of Sinosauropteryx have been found, including few samples of protofeathers,...
Tyrannosaurus, meaning “tyrant lizard,” was a genus of theropod dinosaur from the Late Cretaceous Period (68 to 65 million years ago). It was among the last non-avian dinosaurs to exist prior to the Cretaceous-Tertiary extinction event. Perhaps the most famous Tyrannosaurus species, T. rex, was named in 1905 by Henry Fairfield Osborn, president of the American Museum of Natural History (AMNH). Teeth belonging to Tyrannosaurus were first discovered in 1874 by A. Lakes near Golden...
