New research in the Proceedings of the National Academy of Sciences shows younger groups of organisms, on average, accumulate diversity much more quickly than older groups.
Whale barnacles add new shell throughout the year that has been shown to reflect, through oxygen isotope ratios, the conditions of the seas through which the whale traveled. UC Berkeley paleobiologists have now shown that fossilized whale barnacles retain this isotopic signature, revealing the ocean conditions through which whales traveled millions of years ago. This could help reveal details about whale evolution and ancient migration routes, and help anticipate whale adaptation to climate change.
Scientists from The Australian National University (ANU) have discovered that 558 million-year-old Dickinsonia fossils do not reveal all of the features of the earliest known animals, which potentially had mouths and guts.
Long-distance migrations are common for large whales, but when in their evolutionary past did whales begin to migrate and why? Scientists from the Smithsonian Tropical Research Institute and the University of California, Berkeley looked for these answers in fossil whale barnacles.
University of Alberta paleontologists have just reported the world's biggest Tyrannosaurus rex and the largest dinosaur skeleton ever found in Canada. The 13-metre-long T. rex, nicknamed 'Scotty,' lived in prehistoric Saskatchewan 66 million years ago.
Using their own laser imaging technology, Dr Michael Pittman from the Department of Earth Sciences at The University of Hong Kong and Thomas G Kaye from the Foundation for Scientific Advancement in the USA determined the lifestyle of a special hatchling bird by revealing the previously unknown feathering preserved in the fossil specimen found in the ~125 million-year-old Early Cretaceous fossil beds of Los Hoyas, Spain.
Researchers have discovered an early Cambrian fossil assemblage located along the bank of the Danshui River in China.
One of the ocean's little known carnivores has been allocated a new place in the evolutionary tree of life after scientists discovered its unmistakable resemblance with other sea-floor dwelling creatures.
Ohio University researchers announced a new species of mammal from the Age of Dinosaurs, representing the most complete mammal from the Cretaceous Period of continental Africa, and providing tantalizing insights into the past diversity of mammals on the planet.
UMD biologist finds alligators build neural maps of sound the way birds do, suggesting the hearing strategy existed in their common ancestor, the dinosaurs.
