Homo sapiens, Neanderthals and other recent human relatives may have begun hunting large mammal species down to size - by way of extinction - at least 90,000 years earlier than previously thought, says a new study published in the journal Science. The magnitude and scale of the extinction wave surpassed any other recorded during the last 66 million years, according to the study.
The dispersal of humans out of Africa coincided with a dramatic global reduction in the size of mammals, a new study reveals.
Scientists have long wondered why the physical traits of Neanderthals, the ancestors of modern humans, differ greatly from today's man. Now, a research team led by a professor at the University of New England in Australia, with the aid of an anatomy and fluid dynamics expert at NYIT College of Osteopathic Medicine at Arkansas State University (NYITCOM at A-State), may have the answer.
University of Otago paleontologists are rewriting the history of New Zealand's ancient whales by describing a previously unknown genus of baleen whale, alive more than 27.5 million years ago and found in the Hakataramea Valley, South Canterbury.
A sea turtle discovered in Alabama is a new species from the Late Cretaceous epoch, according to a study published April 18, 2018 in the open-access journal PLOS ONE by Drew Gentry from the University of Alabama at Birmingham, Ala., USA, and colleagues.
A fossil slab discovered in Kansas 70 years ago and twice misidentified -- first as a green alga and then as a cephalopod -- has been reinterpreted as the preserved remains of a large cartilaginous fish, the group that includes sharks and rays. In a study published in the Journal of Paleontology, American Museum of Natural History researchers describe the fishy characteristics of the animal, which lived between 70-85 million years ago.
It is commonly understood that the dinosaurs disappeared with a bang -- wiped out by a great meteorite impact on the Earth 66 million years ago. But their origins have been less understood. In a new study, scientists from MUSE -- Museum of Science, Trento, Italy, universities of Ferrara and Padova, Italy and the University of Bristol show that the key expansion of dinosaurs was also triggered by a crisis -- a mass extinction that happened 232 million years ago.
Plants may have exerted greater influence on our terrestrial ecosystems than the megaherbivores that used to roam our landscapes, according to new research by the University of Plymouth, University of Oxford, Queen's University Belfast, Swansea University and the Natural History Museum, London.
A handful of tiny teeth have led scientists to identify the most distant ancestor of today's kangaroos. The fossils were found in the desert heart of Australia, and then hidden away, and almost forgotten in a museum collection for over three decades. The findings are published in the Journal of Vertebrate Paleontology.
By studying calcium in fossil remains in deposits in Morocco and Niger, researchers have been able to reconstruct the food chains of the past, thus explaining how so many predators could coexist in the dinosaurs' time. This study was conducted by researchers from the CNRS, ENS de Lyon and Claude Bernard Lyon 1 University, in partnership with the French National Museum of Natural History and Sorbonne University.
