Missouri S&T Geologist Leads $2.1M National Science Foundation Research Effort to Study Earth’s Greatest Mass Extinction

Missouri S&T geologist Dr. Wan Yang has devoted his academic career to unlocking the mysteries of thePermian mass extinction more than 250 million years ago. That geological odyssey now finds him leading an 11-institution consortium that’s been collectively awarded a $2.1 million National Science Foundation research grant.

When Ancient Fossil DNA Isn’t Available, Ancient Glycans May Help Trace Human Evolution

allia_bay_excavation.jpg

Researchers at University of California San Diego School of Medicine and collaborators discovered a new kind of glycan (sugar chain) that survives even in a 4 million-year-old animal fossil from Kenya, under conditions where ancient DNA does not. While ancient hominin fossils are not yet available for glycan analysis, this proof-of-concept study, published September 11 in Proceedings of the National Academy of Sciences, sets the stage for unprecedented explorations of human origins and diet.

Study Uses Robot to Probe Mystery of Prehistoric Sea Creature’s Swimming Style

A new study led by the University of Southampton has shed light on the swimming style of plesiosaurs by creating a robot to mimic its movements.

Woolly Rhino Neck Ribs Provide Clues About Their Decline and Eventual Extinction

woolly_rhino_cervical_ribs.jpg

Researchers from the Naturalis Biodiversity Center in Leiden examined woolly rhino and modern rhino neck vertebrae from several European and American museum collections and noticed that the remains of woolly rhinos from the North Sea often possess a ‘cervical’ (neck) rib—in contrast to modern rhinos. The study, published in the open access journal PeerJ today, reports on the incidence of abnormal cervical vertebrae in woolly rhinos. Given the considerable birth defects that are associated with this condition, the researchers argue it is very possible that developmental abnormalities contributed towards the eventual extinction of these late Pleistocene rhinos.

Understanding Caribbean Mammal Extinctions of the Past Spurs Renewed Focus on Conservation

SiobahnCookeCaveFossils.JPG

A Johns Hopkins paleontologist and her collaborative team of scientists report they have clear evidence that the arrival of humans and subsequent human activity throughout the islands of the Caribbean were likely the primary causes of the extinction of native mammal species there. The evidence, they say, highlights the need for urgent human intervention to protect the native mammal species still inhabiting the region.

A Potential Breeding Site of a Miocene Era Baleen Whale

Tsai2017paleobreedingFig3.jpg

Baleen whales are amongst the largest animals to have ever lived and yet very little is known about their breeding habits. One researcher’s second look at previously found baleen whale fossils from Japan provides new evidence of a now long-gone breeding ground of the extinct baleen whale Parietobalaena yamaokai dating back over 15 million years.

Unique Imaging of a Dinosaur’s Skull Tells Evolutionary Tale

Researchers using Los Alamos’ unique neutron-imaging and high-energy X-ray capabilities have exposed the inner structures of the fossil skull of a 74-million-year-old tyrannosauroid dinosaur nicknamed the Bisti Beast in the highest-resolution scan of tyrannosaur skull ever done.

First Winged Mammals From the Jurassic Period Discovered

Two 160 million-year-old mammal fossils discovered in China show that the forerunners of mammals in the Jurassic Period evolved to glide and live in trees. With long limbs, long hand and foot fingers, and wing-like membranes for tree-to-tree gliding, Maiopatagium furculiferum and Vilevolodon diplomylos are the oldest known gliders in the long history of early mammals.
