  • The King of the Dinosaurs just got even BIGGER! T. Rex was 50ft long and weighed up to 15 TONNES - 70% heavier than previously thought, study claims

    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...

Credit: Engraving by Ernest Grise, photographed by William Henry Jackson. 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...
  • Humans Reached Argentina by 20,000 Years Ago — and They May Have Survived by Eating Giant Armadillos, Study Suggests

    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...
  • Scientists Found a Dinosaur's Face, Complete With Its Skin

    07/13/2024 6:55:55 AM PDT · by SunkenCiv · 40 replies
    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...
  • Wine drinkers may have dinosaurs to thank after 60M-year-old grape fossil seeds are found by scientists

    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...

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...

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...

(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....

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...

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.

A fossil of the Jefferson's Ground Sloth, an animal that paleontologists had no idea was in this area of the state until a few curious kids unearthed it. “They were building a dam, looking for crawdads,” said Bryn Evans, a teacher who was with the students when they found the fossil. “They're just in the mud pulling things out and then one of them comes up and is like, 'This isn't a stick, this is a bone!'” What the Tara Redwood School students discovered was...

    The woolly mammoth could roam the Earth once again. That’s the goal of Colossal Biosciences as the biotech company announced a major breakthrough Wednesday in its mission to revive the 6-ton, 16-foot animal back from extinction. The Dallas-based company said it has created a set of stem cells from an Asian elephant in hopes of bringing back a creature that would be eerily similar to the woolly mammoth, according to reports. “This is probably the most significant step in the early stages of this project,” said geneticist and company co-founder George Church, a Harvard University professor, according to NPR.

    Extinct marine lizard the size of an orca with sharp teeth and a strong jaw was a top predator during the dinosaur age. Paleontologists in Morocco have discovered the fossilized remains of a huge, never-before-seen species of marine lizard with "dagger-like" teeth. The reptile was around 26 feet (8 meters) long — about the same length as an orca — and hunted in the Atlantic Ocean off the coast of what is now Africa at the end of the dinosaur age, about 66 million years ago, according to a study published March 1 in the journal Cretaceous Research. The creature...

    A team of international scientists have discovered 240-million-year-old fossils from the Triassic period in China that one scientist described as a "long and snake-like, mythical Chinese dragon." The 16-foot-long aquatic reptile, called Dinocephalosaurus orientalis, has 32 separate neck vertebrae – an extremely long neck, according to the National Museums of Scotland, which announced the news on Friday. The new fossil has a snake-like appearance and flippers and was found in the Guizhou Province of southern China. Dinocephalosaurus orientalis was first identified in 2003 when its skull was found, but this more complete fossil discovery has "allowed scientists to depict the...
