A group of scientists, led by paleontologist Louis L. Jacobs, an Emeritus Professor President of the Institute for the Study of Earth and Man at the Southern Methodist University Campus in Dallas, Texas, have made a significant discovery. The scientists found matching dinosaur footprints on two separate continents, South America and Africa. In Brazil and Cameroon, over 260 footprints were uncovered. These footprints show where dinosaurs once roamed freely on the two continents millions of years ago before South America and Africa drifted apart. Jacobs explained that the footprints were not only similar in age but also in their geological...

In a new study published Thursday in the journal Science, researchers pieced together the chemical identity of the asteroid that fueled the planet’s fifth mass extinction event. Sixty-six million years ago, the story of life on Earth took a dramatic turn when an asteroid collided with what’s now the Yucatán Peninsula in Chicxulub, Mexico. The aftereffects of the collision resulted in the extinction of an estimated 75% of animal species, including most dinosaurs except for birds. But practically nothing of the asteroid itself remains. In a new study published Thursday in the journal Science, researchers pieced together the chemical identity...

About 20 fragments were found, including a skull, rib sections, vertebra, a front leg bone and a kneecap, all believed to come from the same mastodonArchaeologists in Iowa have uncovered parts of a mastodon fossil, including its skull, that they believe dates back to when the first humans lived on Earth. Over the course of a 12-day excavation, staff from the University of Iowa's Office of the State Archaeologist worked with local community members to recover the bones. About 20 fragments were found, including a skull, rib sections, vertebra, a front leg bone and a kneecap, all believed to come...

It looks like the original explanation for where Homo floresiensis came from was right all along. The Hobbit humerus fragment (left) from Mata Menge next to one from Liang Bua to scale, and the full collection of bones from the most complete Liang Bua Hobbit. Image Credit: Yousuke Kaifu ================================================================================ Three new fossils, including part of a humerus, have been found at Mata Menge on the Indonesian island of Flores. They indicate that Homo floresiensis, popularly known as Hobbits, were descended from Homo erectus, and became small relatively soon after arriving on Flores. Indeed, it seems at least some Hobbits...

A den of 38-million-year-old snakes were found in the White River Formation near Douglas, Wyoming, have paleontologists super excited. They're among the most important complete fossils of snakes ever found. ======================================================================== Two of the three specimens of Hibernophis breithaupti, the 38-million-year-old snake from the White River Formation near Douglas. These snakes are members of the boid family, which includes modern-day anacondas and Wyoming's rubber boas. (Courtesy Jasmine Croghan) ================================================================== Around 38 million years ago, three small snakes slithered into a burrow seeking shelter from an apocalypse blanketing their world in volcanic ash. They never escaped, becoming entombed in the spot...

With 60 razor-sharp teeth and jaws so powerful they could crush a car, the King of the Dinosaurs would already have been a terrifying sight.But if that wasn't enough, the T. Rex may have been 70 per cent heavier than previously thought – weighing up to 15 tonnes – according to a study...The palaeontologists found that the largest known T. Rex fossils probably fall in the 99th percentile – representing the top 1 per cent of body size – but finding one would require excavating fossils for another 1,000 years...Meanwhile, a separate study suggests that the T. Rex may also...

Prehistoric humans hunt a woolly mammoth. More and more research shows that this species – and at least 46 other species of megaherbivores – were driven to extinction by humans.

Courtesy Getty’s Open Content Program ================================================================== Researchers at Aarhus University have concluded that human hunting, rather than climate change, was the primary factor in the extinction of large mammals over the past 50,000 years. This finding is based on a review of over 300 scientific articles. Over the last 50,000 years, many large species, or megafauna, weighing at least 45...

The discovery of butchered bones belonging to a glyptodont, a giant relative of the armadillo, suggests that humans were living in Argentina 20,000 years ago. Ancient humans may have butchered and eaten a giant armadillo-like creature around 20,000 years ago in what is now Argentina, a new study finds. The discovery of the butchered bones supports a growing body of evidence that people spread throughout the Americas much earlier than previously assumed. During the Late Pleistocene epoch (129,000 to 11,700 years ago), ice sheets and glaciers covered much of the planet, particularly during the Last Glacial Maximum, a period around...

In 2011, archaeologists uncovered one of the most — if not the most — pristine dinosaur fossils yet: a near-whole ankylosaur, complete with its jagged spikes, most of its limbs, armor coating, and some of its guts and stomach contents. The most amazing detail, though? Its uncannily preserved face and skin.It took Mark Mitchell, a technician at Royal Tyrell Museum, an absurd 7,000 hours and nearly six years to meticulously exhume the fossil by delicately chipping away at the surrounding stone. For his efforts, he had the newly discovered specie of nodosaur — a type of ankylosaur — named after...

Those who enjoy wine may have prehistoric reptiles to thank for today's beverages The earliest fossil grape from the Western Hemisphere is approximately 60 million years old, scientists discovered. A group of scientists with Chicago's Field Museum recently discovered grape fossil seeds that could connect dinosaurs to today's numerous wine offerings. The South America study found nine new species of fossil grapes dating back to at least 19 million years ago — with the oldest one found in a 60-million-year-old rock. Dr. Fabiany Herrera, assistant curator of paleobotany at The Field Museum, led the study. The discovery proved that grapes...

...Bone fragments in a piece of fossilized excrement at a new museum in northern Arizona — aptly called the Poozeum — are among the tinier bits of evidence that indicate T. rex wasn't much of a chewer, but rather swallowed whole chunks of prey.The sample is one of more than 7,000 on display at the museum that opened in May in Williams, a town known for its Wild West shows along Route 66, wildlife attractions and a railway to Grand Canyon National Park...Inside, display cases filled with coprolites — fossilized feces from animals that lived millions of years ago —...

Poitiers =================================================================== Trilobites that date back 508 million years have been found preserved in volcanic matter, revealing never-before-seen details in 3D form. Their fossilization was so rapid that tiny shells have been preserved in situ, and soft tissues including mouthparts and internal organs can still be seen. The trilobites were entombed in pyroclastic flow, which is the hot, dense material that comes hurtling out of volcanoes sometimes reaching speeds as high...

Lokiceratops rangiformis made its home in parts of what's now northern Montana and is thought to have the largest frill horns ever seen among its kind to date. A reconstruction of Lokiceratops surprised by a crocodilian in the 78-million-year-old swamps of northern Montana, USA. Illustration: Andrey Atuchin/Museum of Evolution in Maribo, Denmark. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Scientists have discovered a new, very cool-looking dinosaur. The intricately horned beast is a relative of the famous Triceratops and has been named Lokiceratops rangiformis. It’s thought to have roamed around the western half of North America over 78 million years ago, back when the continent was...

A large fossil discovery has significantly advanced our understanding of dinosaur history in Wales, a region previously believed to be devoid of these prehistoric giants...The research team, led by former Bristol MSc student in Palaeobiology, Owain Evans, uncovered that early Welsh dinosaurs lived over 200 million years ago on a tropical lowland adjacent to the sea. Dinosaur trackways found in Barry and other nearby sites indicate that these prehistoric creatures roamed the warm lowlands.The discovery site, Lavernock Point, is located near Cardiff and Penarth. This area, characterized by cliffs of dark-colored shales and limestones, documents ancient shallow seas. At various...

June 10 (UPI) -- Three young boys out for a hike in North Dakota noticed something sticking out from the ground and were shocked to find out they had discovered a Tyrannosaurus rex fossil. Jessin and Liam Fisher, ages 10 and 7, were out hiking onNorth Dakota Bureau of Land Management land in the badlands, near Marmarth, with their cousin, Kaiden Madsen, 9, and their dad, Sam Fisher, when the family spotted an unusual object sticking out of the ground. They contacted Tyler Lyson, Sam Fisher's high school classmate and now the Curator of Paleontology for the Denver Museum of...

The studied Psittacosaurus under natural (upper half) and UV light (lower half). (Zixiao Yang, Author provided) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Strong but light, beautiful and precisely structured, feathers are the most complex skin appendage that ever evolved in vertebrates. Despite the fact humans have been playing with feathers since prehistory, there's still a lot we don't understand about them. Our new study found that some of the first animals with feathers also had scaly skin like reptiles. Following the debut of the first feathered dinosaur, Sinosauropteryx prima, in 1996, a surge of discoveries has painted an ever more interesting picture of feather evolution....

Welcome to the party, Koleken inakayali, we'll clap for you. La Colonia Formation continues to deliver the new dinosaur goods. Image credit: © Gabriel Díaz Yantén Behold, the tiny arms of a new species of abelisaurid dinosaur, Koleken inakayali. Retrieved from La Colonia Formation in Patagonia, it dates back 70 million years and has an impressively miniature set of arms. Think T. rex’s were mini? You ain’t seen nothing yet. The new tiny-armed species looks similar to the iconic “meat bull” Carnotaurus, made famous from Jurassic World and that love scene in Prehistoric Planet. Koleken is different, however, both in...

Not quite a spider, not a scorpion either – where does Douglassarachne acanthopoda fit in? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Douglassarachne acanthopoda was a more experimental version of a modern harvestman, with distinctive armored legs. Image credit: Paul Selden ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This leggy, spiny fella is Douglassarachne acanthopoda, whom we’ll call Doug for short (only kidding). You might look at this fossilized specimen and confidently declare, “That there’s a spider.” But wait! While D. acanthopoda certainly shares many of the characteristics of modern arachnids, it has enough unique features to give palaentologists a headache when it comes to classifying it. Spiders and their ancestors have...

While we don't like to talk ill of the dead, new physiological analysis has found that the king of the dinosaurs was not so smart after all. It upends previous research that last year likened the brain and neuronal composition of the Tyrannosaurus rex to that of a primate. It's been a rough year or two for the long extinct dinosaur. First, we questioned their teeth, finding that those iconic chompers could very much have been smaller and hidden behind lips, and now an international team of paleontologists, behavioral scientists and neurologists have concluded that the T. rex wasn't smarter...

Trees are believed to have originated hundreds of millions of years ago. Ever since, evidence of these ancient plant sentinels has been in short supply. Now, a new discovery of uniquely 3D tree fossils has opened a window into what the world was like when the planet’s early forests were beginning to evolve, expanding our understanding of the architecture of trees throughout Earth’s history.
