Latest Triassic Stories
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.
Recently, a mysterious seed fern, Lepidopteris baodensis sp. nov., dating to more than 251 million years ago (Ma), was discovered at the Baijiagou of Baode, Shanxi, China, from the Upper Permian Sunjiagou Formation.
Around 250 million years ago, most life on Earth was wiped out in an extinction known as the “Great Dying.” A team led by University of Cincinnati geologist Thomas J. Algeo finds that the end came slowly from thousands of centuries of volcanic activity.
The cataclysmic events that marked the end of the Permian Period some 252 million years ago were a watershed moment in the history of life on Earth.
Earth's largest mass extinction event, the end-Permian mass extinction, occurred some 252 million years ago. An estimated 90 percent of Earth's marine life was eradicated.
While the cause of the mass extinction that occurred between the Permian and Triassic periods is still uncertain, two University of Rhode Island researchers collected data that show that terrestrial biodiversity recovered much faster than previously thought, potentially contradicting several theories for the cause of the extinction.
Harsh living conditions caused by major fluctuations in the carbon content and sea levels, overacidification and oxygen deficiency in the seas triggered the largest mass extinction of all time at the end of the Permian era 252 million years ago.
More than 200 million years ago, mammals and reptiles lived in their own separate worlds on the supercontinent Pangaea, despite little geographical incentive to do so.
Careful dating of new dinosaur fossils and volcanic ash around them by researchers from UC Davis and UC Berkeley casts doubt on the idea that dinosaurs appeared and opportunistically replaced other animals.
Geologists at Brown University and the University of Washington have a cautionary tale: Lose enough species in the oceans, and the entire ecosystem could collapse.
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,...
