A new paper appearing in Biology Letters describes the oldest-known fragmentary bat fossils from Asia, pushing back the evolutionary record for bats on that continent to the dawn of the Eocene and boosting the possibility that the bat family's "mysterious" origins someday might be traced to Asia.
A Case Western Reserve University researcher is leading an interdisciplinary global team that will use state-of-the-art technology to tackle an ancient question: How did ecological factors affect the evolution of our ancestors millions of years ago? The possible answers so intrigued the W. M. Keck Foundation that it awarded Armington Professor Beverly Saylor and her colleagues a $1.2 million grant to explore them.
Dinosaurs were generally huge, but a new study of the unusual alvarezsaurs show that they reduced in size about 100 million years ago when they became specialised ant-eaters.
The tiny beetle Triamyxa coprolithica is the first-ever insect to be described from fossil faeces. The animal the researchers have to thank for the excellent preservation was probably the dinosaur ancestor Silesaurus opolensis, which 230 million years ago ingested the small beetle in large numbers.
Elephants and their forebears were pushed into wipeout by waves of extreme global environmental change, rather than overhunting by early humans, according to new research.
A near-perfectly preserved ancient human fossil known as the Harbin cranium sits in the Geoscience Museum in Hebei GEO University. The largest of known Homo skulls, scientists now say this skull represents a newly discovered human species named Homo longi or "Dragon Man." Their findings, appearing in three papers publishing June 25 in the journal The Innovation, suggest that the Homo longi lineage may be our closest relatives--and has the potential to reshape our understanding of human evolution.
A beetle bores a tree trunk to build a gallery in the wood in order to protect its lay. As it digs the tunnel, it spreads ambrosia fungal spores that will feed the larvae.
The ancient Maya city of Tikal was a bustling metropolis and home to tens of thousands of people.
Associate professor Laura Wasylenki co-authored a new paper in Nature Communications that presents the results of nickel isotope analyses on Late Permian sedimentary rocks. The results demonstrate the power of nickel isotope analyses, which are relatively new, to solve long-standing problems in the geosciences.
New UMD study suggests that everywhere tyrannosaurs rose to dominance, their juveniles took over the ecological role of medium-sized carnivores
Footprints from at least six different species of dinosaur - the very last dinosaurs to walk on UK soil 110 million years ago - have been found in Kent, a new report has announced.
The old cousins of the common woodlice were crawling on Irish land as long as 360 million years ago, according to new analysis of a fossil found in Kilkenny.
An international research team has described a new species of Oculudentavis, providing further evidence that the animal first identified as a hummingbird-sized dinosaur was actually a lizard.
Russian paleontologists discovered the skull of a Pleistocene small cave bear with artificial damage in the Imanay Cave (Bashkiria, Russia).
Coral insights into 1,000 years of seasonal changes in the Arabian Sea warn of significant impacts caused by global warming.
Jack Tseng loves bone-crunching animals -- hyenas are his favorite -- so when paleontologist Joseph Peterson discovered fossilized dinosaur bones that had teeth marks from a juvenile Tyrannosaurus rex, Tseng decided to try to replicate the bite marks and measure how hard those kids could actually chomp down.
A large group of iconic fossils widely believed to shed light on the origins of many of Earth’s animals and the communities they lived in may be hiding a secret. Scientists are the first to model how exceptionally well preserved fossils that record the largest and most intense burst of evolution ever seen could have been moved by mudflows.
Since its discovery in the 1960s, the Jebel Sahaba cemetery (Nile Valley, Sudan), 13 millennia old, was considered to be one of the oldest testimonies to prehistoric warfare.
A strange phenomenon happens with modern blue whales, humpback whales and gray whales: they have teeth in the womb but are born toothless.
Researchers at the University of Washington have discovered the first fossil evidence of an ancient amphibian, Micropholis stowi, from Antarctica. Micropholis lived in the Early Triassic, shortly after Earth's largest mass extinction. It was previously known only from fossils in South Africa.
