Latest Triassic dinosaurs Stories
A team of researchers led by Jahan Ramezani of MIT’s Department of Earth, Atmospheric and Planetary Sciences has discovered evidence that dinosaurs lived in North America millions of years earlier than previously suggested.
An international team of scientists has discovered what they believe to be the earliest example of social behavior in bird-hipped dinosaurs, along with a brand new species, in the Andes Mountains of Venezuela.
Some of the earliest known dinosaurs to have walked the planet were considered to be small dinosaurs like the swift-footed Eoraptor. But researchers have discovered a new dinosaur that may be even older.
The discovery of a 200-million year old fossil of a reptile with extremely pointed teeth, from an area now known New Mexico, is filling a gap in previously known dinosaur evolution.
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.
A new species of dinosaur discovered in Arizona suggests dinosaurs did not spread throughout the world by overpowering other species, but by taking advantage of a natural catastrophe that wiped out their competitors.
New fossil material redefines Azendohsaurus as a peculiar early reptile.
A team of paleontologists has unearthed a previously unknown meat-eating dinosaur from a fossil bone bed in northern New Mexico.
Scientists had thought the dinosaurs rapidly replaced their ancestor species. Now, researchers report in the journal Science they have evidence from northern New Mexico that dinosaurs and their precursor species coexisted for tens of millions of years.
Palaeontologists from the University of Bonn report on an intriguing diagnosis in the 16 December issue of the journal Science. A dinosaur which they have examined was apparently able to vary the speed of its growth according the conditions obtaining in its environment.
Edwin Harris Colbert (September 28, 1905 – November 15, 2001), known as “Ned” to his friends and colleagues, was a distinguished American Paleontologist. He helped popularize the study of dinosaurs through his prolific research, writings, and 40 years of work as a curator at the American Museum of Natural History in New York. Colbert was born in Clarinda, Iowa, but moved to Maryville, Missouri during infancy. Like many young children, and most of his predecessors and contemporaries,...
Plateosaurus, meaning “Broadway lizard,” is a genus of plateosaurid dinosaur from the Late Triassic Period (216 to 199 million years ago), which lived in what is now Central and Northern Europe. It is a primitive sauropodomorph dinosaur. There are two recognized species: the type species P. engelhardti from the late Norian and Rhaetian stages, and the slightly earlier P. gracilis from the lower Norian. Plateosaurus was discovered in 1834 by Johann Friedrich Engelhardt and described...
Segisaurus, meaning "Segi canyon lizard," is a genus of coelophysoid theropod dinosaur from the Early Jurassic Period (183 million years ago). It was discovered by a Navajo Indian -- Max Littlesalt -- in 1933 in Tsegi Canyon, Arizona, for which it was named. Segisaurus is the only dinosaur ever to be excavated from that area. Although it was described in 1936 by paleontologist Charles Lewis Camp, the specimen went relatively ignored for the next half century. When the specimen was...
Zupaysaurus, meaning "devil lizard," is a genus of theropod dinosaur from the Rhaetian stage of the Late Triassic, and possible the Hettangian stage of the Early Jurassic Period of what is now Argentina. It was discovered in the Los Colorados Formation of La Rioja province in Argentina. The formation is normally assigned to the Norian stage (216-203), but has also been assigned to the slightly younger Rhaetian stage (203-200 million years ago), where Zupaysaurus was found. The type...
Staurikosaurus, meaning "Southern Cross lizard," is a genus of dinosaur from the Carnian age of the Late Triassic Period (225 million years ago). The first known specimen was recovered from the paleontological site Jazigo Cinco of the Santa Maria Formation, in Rio Grande do Sul, Brazil. The genus name refers to the star constellation, "The Southern Cross," pictured in the coat of arms of Brazil, which is only visible in the southern hemisphere. In 1970, when Staurikosaurus was first...
