| Confiscated fossil turns out to be exceptional flying reptile from Brazil Posted: 25 Aug 2021 11:31 AM PDT A fossil acquired in a police raid has turned out to be one of the best-preserved flying reptiles ever found, according to a new study. |
| Pictograms are first written accounts of earthquakes in pre-Hispanic Mexico Posted: 25 Aug 2021 11:30 AM PDT The Codex Telleriano Remensis, created in the 16th century in Mexico, depicts earthquakes in pictograms that are the first written evidence of earthquakes in the Americas in pre-Hispanic times, according to a pair of researchers who have systematically studied the country's historical earthquakes. |
| Fossils illuminate dinosaur evolution in eastern North America Posted: 25 Aug 2021 11:30 AM PDT Tyrannosaurus rex, the fearsome predator that once roamed what is now western North America, appears to have had an East Coast cousin. A new study describes two dinosaurs that inhabited Appalachia -- a once isolated land mass that today composes much of the eastern United States -- about 85 million years ago: an herbivorous duck-billed hadrosaur and a carnivorous tyrannosaur. |
| Central European prehistory was highly dynamic Posted: 25 Aug 2021 11:30 AM PDT Recent archaeogenetic studies have shown that human movements like migrations and expansions played a major role in driving the spread of cultures and genes in ancient Europe. However, it is only now with detailed regional studies and dense sampling that researchers start to better understand the magnitude, rate and social implications of these changes. |
| Oldest genome from Wallacea shows previously unknown ancient human relations Posted: 25 Aug 2021 08:36 AM PDT The oldest genome of a modern human from the Wallacea region -- the islands between western Indonesia and Papua New Guinea -- indicates a previously undescribed ancient human relationship. Researchers were able to isolate sufficient genetic material from the skull of an individual buried more than 7,000 years ago on the Indonesian island of Sulawesi. It belonged to a hunter-gatherer society and was interred at the site now called Leang Panninge ('Bat Cave'). A large part of the genetic code matched that of today's Papua New Guineans and Aboriginal Australians. Yet portions of the genome did not match these groups. This brings new surprises about the evolution of modern humans. |
| CT scan of an ancient reptile skull reveals little evolutionary change over 22 million years Posted: 25 Aug 2021 07:14 AM PDT A CT scan of the skull of a long-necked plesiosaur shows the cranial architecture of these long-extinct marine reptiles didn't evolve much over 22 million years that they lived during the Cretaceous time. That's very unusual, according to a paleontologist. |
