Jurassic ichthyosaurs divided food resources to co-exist, researchers find

Newswise — Early Jurassic ichthyosaur juveniles show predatory specialisations, scientists at the University of Bristol have revealed. Their findings, published today in Journal of Anatomy, suggest that physical differences in their snouts show they evolved to have different diets and were not competing for the same resource. Ichthyosaurs, the classic ‘sea dragons’, were dolphin-shaped marine… Continue reading Jurassic ichthyosaurs divided food resources to co-exist, researchers find

Geneticist who unmasked lives of ancient humans wins medicine Nobel

Svante Pääbo has been awarded a Nobel prize for discoveries about the genomes of extinct hominins and human evolution.Credit: Alamy This year’s Nobel Prize in Physiology or Medicine has been awarded for pioneering studies of human evolution that harnessed precious snippets of DNA found in fossils that are tens of thousands of years old. The… Continue reading Geneticist who unmasked lives of ancient humans wins medicine Nobel

Ancient ‘shark’ from China is humans’ oldest jawed ancestor

Newswise — Living sharks are often portrayed as the apex predators of the marine realm. Paleontologists have been able to identify fossils of their extinct ancestors that date back hundreds of millions of years to a time known as the Palaeozoic period. These early “sharks,” known as acanthodians, bristled with spines. In contrast to modern sharks,… Continue reading Ancient ‘shark’ from China is humans’ oldest jawed ancestor

Ethics, law, and politics in palaeontological research: The case of Myanmar amber

Fossils entombed in amber provide exceptional and unique insights into the morphology and evolution of organisms that inhabited past forest ecosystems1. Amber, which is fossilised plant resin, of various geological ages can be found in several parts of the world, including the Baltic region of Europe, Alaska, Madagascar, Lebanon, the Dominican Republic, and Canada. Amber… Continue reading Ethics, law, and politics in palaeontological research: The case of Myanmar amber
