A team of paleontologists led by Virginia Tech’s Michelle Stocker and Sterling Nesbitt of the Department of Geosciences have identified fossil fragments of what are thought to be the oldest known frogs in North America.
Not by meteorite alone did the dinosaurs die off. Lawrence Livermore National Laboratory research scientist Kyle Samperton and colleagues present the most compelling evidence yet that massive volcanic eruptions in the Deccan Traps region of India contributed to the fall of the dinosaurs – also known as the end-Cretaceous mass extinction – approximately 66 million years ago.
Total human carbon dioxide emissions could match those of Earth's last major greenhouse warming event in fewer than five generations, according to a new University of Michigan study.
The 3.7-billion-year-old structures were considered the first evidence for life on the planet; new evidence suggests differently.
A research team has discovered a previously unknown species of marsupial that lived in Alaska's Arctic during the era of dinosaurs, adding a vivid new detail to a complex ancient landscape.
Tiny, opossum-like animal lived alongside dinosaurs in Alaska's polar forests roughly 69 million years ago and faced months of winter darkness.
The rich levels of biodiversity on land seen across the globe today are not a recent phenomenon: diversity on land has been similar for at least the last 60 million years, since soon after the extinction of the dinosaurs.
An exceptional sauropod dinosaur specimen from the middle Cretaceous of Tanzania represents a unique species and provides new insights into sauropod evolution, according to a study published February 13, 2019 in the open-access journal PLOS ONE by Eric Gorscak of Midwestern University, Illinois, and Patrick O’Connor of Ohio University, USA.
This research letter documents bone cancer in a 240-million-year-old stem-turtle from the Triassic period, helping to provide more data about the history of cancer in tetrapod evolution. This is a case study about a highly malignant bone tumor on the femur of a shell-less stem-turtle. The appearance of the tumor in the fossilized specimen conforms with present-day periosteal osteosarcoma in humans.
A new oviraptorosaur species from the Late Cretaceous was discovered in Mongolia, according to a study published in February 6, 2019 in the open-access journal PLOS ONE by Yuong-Nam Lee from Seoul National University, South Korea, and colleagues.
The University of Michigan Museum of Natural History announced today it will re-open to the public Sunday, April 14, in a brand-new building.
A 150-year-old fossil feather mystery has been solved by an international research team including Dr Michael Pittman from the Department of Earth Sciences, The University of Hong Kong.
Scientists have just discovered a dinosaur relative that lived in Antarctica 250 million years ago. The iguana-sized reptile's genus name, Antarctanax, means "Antarctic king."
A much debated ancient human skull from Mongolia has been dated and genetically analysed, showing that it is the earliest modern human yet found in the region
Long-necked dinosaurs (sauropods) could orient their forefeet both forward and sideways. The orientation of their feet depended on the speed and centre of mass of the animals.
In a paper published by Evolution, research led by Swansea University's Dr Catalina Pimiento and co-authored by an international team of scientists from the UK, Europe and the USA examined the biological traits of all sharks and rays before running a series of evolutionary models to seek how gigantism evolved over time.
Paleontologists at the University of Chicago have discovered the first detailed fossil of a hagfish, the slimy, eel-like carrion feeders of the ocean. The 100-million-year-old fossil helps answer questions about when these ancient, jawless fish branched off the evolutionary tree from the lineage that gave rise to modern-day jawed vertebrates, including bony fish and humans.
The world of the dinosaurs just got a bit more bizarre with a newly discovered species of freshwater shark whose tiny teeth resemble the alien ships from the popular 1980s video game Galaga.
The fossil site of Malapa in the Cradle of Humankind, South Africa, discovered by Lee Berger of the University of the Witwatersrand, Johannesburg, in August 2008, has been one of the most productive sites of the 21st century for fossils of early human ancestors or hominins. A new hominin species, Australopithecus sediba (Au. sediba), was named by Berger and his colleagues, following the discovery of two partial skeletons just under two million years old, a juvenile male individual-- Malapa Hominin 1 (MH1)-- and an adult female, Malapa Hominin 2 (MH2). The skeletons are under the custodianship of the University of the Witwatersrand, where they are being kept.
Separate skeletons suggested to be from different early hominin species are, in fact, from the same species, a team of anthropologists has concluded in a comprehensive analysis of remains first discovered a decade ago.
