Published Tiny roundworms carve out unique parasitic niche inside pseudoscorpion's protective covering (via sciencedaily.com) Original source
In a parasitic first, a Baltic amber specimen has revealed that millions of years ago tiny worms known as nematodes were living inside of and feeding on the outer protective layer of pseudoscorpions.
Published Fishy mystery of marine reptile solved (via sciencedaily.com) Original source
The identity of a prehistoric marine reptile has finally been revealed after experts discovered that some of its remains actually belonged to fish.
Published 'Missing' early sea sponges discovered (via sciencedaily.com) Original source
Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for years.
Published Gigantic Jurassic pterosaur fossil unearthed in Oxfordshire, UK (via sciencedaily.com) Original source
A team of palaeontologists has discovered a fossil of a gigantic flying reptile from the Jurassic period with an estimated wingspan of more than three metres -- making it one of the largest pterosaurs ever found from that era.
Published 'Ugly' fossil places extinct saber-toothed cat on Texas coast (via sciencedaily.com) Original source
This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to the fossil that met the eye: a hidden canine tooth that had not yet erupted from the jaw bone. It was just what researchers needed to identify the fossil as belonging to a Homotherium, a genus of large cat that roamed much of the Earth for millions of years.
Published Origins of 'Welsh dragons' finally exposed by experts (via sciencedaily.com) Original source
A large fossil discovery has helped shed light on the history of dinosaurs in Wales.
Published Musankwa sanyatiensis, a new dinosaur from Zimbabwe (via sciencedaily.com) Original source
Fossils found on the shoreline of Lake Kariba in Zimbabwe represent a completely new dinosaur species. This remarkable find, named Musankwa sanyatiensis, marks only the fourth dinosaur species named from Zimbabwe.
Published Bringing back an ancient bird (via sciencedaily.com) Original source
Using ancient DNA extracted from the toe bone of a museum specimen, biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. The work is the first complete genetic map of the turkey-sized bird whose distant living cousins include the ostrich, emu, and kiwi.
Published Florida fossil porcupine solves a prickly dilemma 10-million years in the making (via sciencedaily.com) Original source
An exceptionally rare fossilized porcupine skeleton discovered in Florida has allowed researchers to trace the evolutionary history for one of North America's rarest mammals.
Published Ancient people hunted extinct elephants at Tagua Tagua Lake in Chile 12,000 years ago (via sciencedaily.com) Original source
Thousands of years ago, early hunter-gatherers returned regularly to Tagua Tagua Lake in Chile to hunt ancient elephants and take advantage of other local resources, according to a new study.
Published 3,500-year-old Mycenaean armor was suitable for extended battle (via sciencedaily.com) Original source
A 3,500-year-old suit of Mycenaean armour may have been used in battle -- and not just for ceremonial purposes as previously thought -- new research reveals.
Published Researchers discover hidden step in dinosaur feather evolution (via sciencedaily.com) Original source
Scientists discover 'zoned development' in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers. A new dinosaur skin fossil has been found to be composed of silica -- the same as glass.
Published Evolutionary history of extinct duck revealed (via sciencedaily.com) Original source
The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the Brazilian merganser.
Published Diverse headgear in hoofed mammals evolved from common ancestor (via sciencedaily.com) Original source
From the small ossicones on a giraffe to the gigantic antlers of a male moose -- which can grow as wide as a car -- the headgear of ruminant hooved mammals is extremely diverse, and new research suggests that despite the physical differences, fundamental aspects of these bony adaptations likely evolved from a common ancestor.
Published Ancient arachnid from coal forests of America stands out for its spiny legs (via sciencedaily.com) Original source
The spiny legged 308-million-year-old arachnid Douglassarachne acanthopoda was discovered the famous Mazon Creek locality.
Published How did sabre-toothed tigers acquire their long upper canine teeth? (via sciencedaily.com) Original source
In a groundbreaking study an international team of scientists has investigated the evolutionary patterns behind the development of sabre teeth, with some unexpected results along the way.
Published Human activity is making it harder for scientists to interpret oceans' past (via sciencedaily.com) Original source
New research shows human activity is significantly altering the ways in which marine organisms are preserved, with lasting effects that can both improve and impair the fossil record.
Published Rock solid evidence: Angola geology reveals prehistoric split between South America and Africa (via sciencedaily.com) Original source
A research team has found that ancient rocks and fossils from long-extinct marine reptiles in Angola clearly show a key part of Earth's past -- the splitting of South America and Africa and the subsequent formation of the South Atlantic Ocean.
Published Revised dating of the Liujiang skeleton renews understanding of human occupation of China (via sciencedaily.com) Original source
Researchers have provided new age estimates and revised provenance information for the Liujiang human fossils, shedding light on the presence of Homo sapiens in the region. Using advanced dating techniques including U-series dating on human fossils, and radiocarbon and optically stimulated luminescence dating on fossil-bearing sediments, the study revealed new ages ranging from approximately 33,000 to 23,000 years ago. Previously, studies had reported ages of up to 227,000 years of age for the skeleton.
Published T. Rex not as smart as previously claimed (via sciencedaily.com) Original source
Dinosaurs were likely as smart as reptiles but not as intelligent as monkeys.
