This new study applied X-ray imaging to several 3-million-year-old fossils in order to untangle the story of key pigments in ancient animals and reveal how we might recognize the chemical signatures of specific red pigments in long extinct animals to determine how they evolved.
Researchers have for the first time detected chemical traces of red pigment in an ancient fossil -- an exceptionally well-preserved mouse, not unlike today's field mice, that roamed the fields of what is now the German village of Willershausen around 3 million years ago.
When the bones of an ancient heron were unearthed at a North Florida fossil site, the find wasn't made by researchers but by two Florida Museum of Natural History volunteers. A previously unknown genus and species, the heron has been named Taphophoyx hodgei.
A network of fish ponds supported a permanent human settlement in the seasonal drylands of Bolivia more than one thousand years ago, according to a new study published May 15, 2019 in the open-access journal PLOS ONE by Gabriela Prestes-Carneiro of Federal University of Western Para, Brazil, and colleagues.
Neanderthals and modern humans diverged at least 800,000 years ago, substantially earlier than indicated by most DNA-based estimates, according to new research by a UCL academic.
UNLV geoscientist, student among international research team behind discovery of ancient monkey species that lived in Africa 22 million years ago.
The CT scan revealed cochlear coiling with more turns than in animals with echolocation, indicating hearing more similar to the cloven-hoofed, terrestrial mammals dolphins came from than the sleek sea creatures they are today.
Evidence of crawling in an Italian cave system sheds new light on how late Stone Age humans behaved as a group, especially when exploring new grounds, says a study published today in eLife.
Animal remains found at archaeological sites tell the millennia-long story of how humans have hunted, domesticated and transported wildlife, altered landscapes and responded to environmental changes such as shifting temperatures and sea levels. Now, that story is available digitally through a new open-access data platform known as ZooArchNet, which links records of animals across biological and archaeological databases.
A years-long study that involved scientists and experiments at Berkeley Lab and UC Berkeley concludes that an odd assortment of particles found in beach sands in Japan are most likely fallout debris from the 1945 Hiroshima A-bomb blast.
