    A peculiar, 220-million-year-old species of burrowing reptiles that evaded scientists has been found, fossilized. A team of National Park Service interns are credited with its discovery. Hidden in a once-vibrant part of Arizona's Petrified Forest National Park, the burgeoning paleontologists unearthed fossils of the Skybalonyx skapter, an "anteater-like reptile" that probably predates dinosaurs, according to findings published this month in the Journal of Vertebrate Paleontology. It's a new species of a reptile previously thought to only live in trees. The unusual Skybalonyx skapter belongs to the group Drepanosaur, often considered the ugly duckling of reptiles (perhaps partly because they bore...

    Around 99 million years ago, a juvenile cockroach met a hellish fate. It was snapped up by the jaws of a Cretaceous hell ant, a fierce predator with long, curving mandibles that swept up toward the top of the ant's head. Just moments later, the ant and roach were trapped in sticky sap that eventually turned to amber, providing scientists with a first glimpse of how the weird-faced ants trapped prey. The profile of a hell ant, with exaggerated upward-facing jaws that arc like the Grim Reaper's scythe, is unlike that of any ant alive today. Adding to the facial...

    The rare fossils are helping scientists understand how ancient bugs hatched from their eggs The insects became trapped in the sticky resin 130million years ago, shortly after bursting through the shell – and scientists aren't sure how the creatures met their grisly fate. The amazing fossils are helping researchers understand how ancient bugs hatched and took their first steps in the ancient world. Like many modern animals, the insects used a tool known as an egg-burster to smash through the egg shell. "The structures that make hatching possible tend to disappear quickly once egg-laying animals hatch, so obtaining fossil evidence...

    A 99-million-year-old beetle has been found, trapped in amber, stunning scientists. The new beetle, known as Propiestus archaicus, was found in Hukawng Valley in the northern part Myanmar, near China's southern border. P. archaicus is a distant relative of today's rove beetles, found in South America and the southern part of Arizona, revealing that the continents shifted rapidly millions of years ago to what we now see today. "This is a very rare find," Shuhei Yamamoto said, a Field Museum researcher and lead author of a paper in the Journal of Systematic Palaeontology, said in a statement. Thanks to the...

    The newly-reported specimen was obtained from an amber deposit in the Angbamo area in Myanmar’s Kachin province.The fossil is a 1.6-inch (4.75 cm) long postcranial skeleton made up of 97 vertebrae; the snake’s head is missing. It dates from the Late Cretaceous epoch, approximately 99 million years ago.“This snake, named Xiaophis myanmarensis, is linked to ancient snakes from Argentina, Africa, India and Australia,” said University of Alberta’s Professor Michael Caldwell.“It is an important — and until now, missing — component of understanding snake evolution from southern continents, that is Gondwana, in the mid-Mesozoic.” “At 99 million years old, it dates...

    The 99-million-year-old hatchling from the Cretaceous Period is the best preserved of its kind The remains of a baby bird from the time of the dinosaurs have been discovered in a specimen of 99-million-year-old amber, according to scientists writing in the journal Gondwana Research. The hatchling belonged to a major group of birds known as enantiornithes, which went extinct along with dinosaurs at the end of the Cretaceous period, about 65 million years ago. Funded in part by the National Geographic Society's Expeditions Council, this discovery is providing critical new information about these ancient, toothed birds and how they differed...

    Using CT scans, researchers discovered a malignant bone cancer in the fibula of a horned dinosaur that lived 75 million years ago. Photo by Royal Ontario Museum/McMaster University =========================================================================== Aug. 4 (UPI) -- For the first time, scientists have diagnosed a dinosaur with osteosarcoma, an aggressive, malignant bone cancer, according to a study published in The Lancet Oncology. The tumor was found on the fibula, or lower leg bone, of a Centrosaurus apertus specimen, a plant-eating, horned dinosaur that lived 75 million years ago. Shortly after its original discovery in Dinosaur Provincial Park in Alberta in 1989, paleontologists misdiagnosed the...
  • Scientists revive 100 million-year-old microbes from the sea

    The tiny organisms had survived in the South Pacific seabed - in sediment that is poor in nutrients, but has enough oxygen to allow them to live. Microbes are among the earth's simplest organisms, and some can live in extreme environments where more developed life forms cannot survive. After incubation by the scientists, the microbes began to eat and multiply. Professor and study co-author Steven D'Hondt, from the University of Rhode Island, said the microbes came from the oldest samples taken from the seabed. "In the oldest sediment we've drilled, with the least amount of food, there are still living...

    When the paper was published, many mainstream publications were intrigued by the story and wrote about the findings, giving the team from China, the U.S. and Canada a bit of notoriety. But shortly thereafter, others in the field began questioning the categorization of the fossil—many suggested it appeared to be a lizard, which is a different group of reptiles from the dinosaurs. The specimen in question is a very small skull embedded in amber, believed to be approximately 100 million years old—dating it to the time of the dinosaurs. The researchers described the specimen as a bird-like skull less than...

    In studying the hundreds of offspring produced, which some on the internet have named sturddlefish, the researchers found that they fell into one of three main categories: those that looked mostly like their mothers, those that looked mostly like their fathers and those that inherited features of both parents. Both of the parent fish are endangered, and they would not have had any chance of reproducing in the wild—as their names suggest, the paddlefish live in the U.S. and the sturgeon live in Russia. They are both considered to be "living fossils" by scientists because they have not changed very...

    To understand how and why color is preserved in some amber fossils but not in others, and whether the colors seen in fossils are the same as the ones insects paraded more than 99 million years ago, the researchers used a diamond knife blades to cut through the exoskeleton of two of the colorful amber wasps and a sample of normal dull cuticle. Using electron microscopy, they were able to show that colorful amber fossils have a well-preserved exoskeleton nanostructure that scatters light. The unaltered nanostructure of colored insects suggested that the colors preserved in amber may be the same...

    Although past research has suggested Tyrannosaurus rex was related to chickens, now findings hint this giant predator might have acted chicken too. Instead of picking on dinosaurs its own size, researchers now suggest T. rex was a baby killer that liked to swallow defenseless prey whole. Fossil evidence of attacks of tyrannosaurs or similar gargantuan "theropods" on triceratops and duck-billed dinosaurs has been uncovered before, conjuring images of titanic clashes.

    Artist's reconstruction of the world's oldest modern bird, Asteriornis maastrichtensis, in its original environment. 66.7 million years ago parts of Belgium were covered by a shallow sea, and conditions were similar to modern tropical beaches like The Bahamas. Asteriornis lived at the end of the Age of Dinosaurs, a time when mosasaurs (giant marine reptiles) swam in the oceans, and Tyrannosaurus rex lived on land. Asteriornis had fairly long legs and may have prowled the tropical shoreline.

    Researchers surveyed more than 2,000 dinosaur bones from the Jurassic Mygatt-Moore Quarry, a 152-million-year-old fossil deposit in western Colorado, looking for bite marks. They found more than they were expecting. Big theropod dinosaurs such as Allosaurus and Ceratosaurus ate pretty much everything - including each other... There were theropod bites on the large-bodied sauropods, whose gigantic bones dominate the assemblage, bites on the heavily armored Mymoorapelta, and lots of bites on theropods too, especially the common remains of Allosaurus. There were hundreds of them, in frequencies far above the norm for dinosaur-dominated fossil sites. Some were on meaty bones like...

    A team of paleontologists from the United States, Canada and Argentina has analyzed the fossilized eggs of two different non-avian dinosaurs, Protoceratops and Mussaurus, and found that the eggs resembled those of turtles in their microstructure, composition, and mechanical properties. They've also found that hard-shelled eggs evolved at least three times independently in the dinosaur family tree. For many years there was scant fossil evidence of dinosaur eggs, and all known examples were characterized by thick, calcified shells -- leading paleontologists to speculate that all dinosaur eggs were hard-shelled, like those of modern crocodiles and birds. "The assumption has always...

    Named Antarcticoolithus bradyi, the new fossil is the first fossilized egg found in Antarctica. The specimen exceeds eggs of all known non-avian dinosaurs in volume and differs from them in structure. Measuring 29 by 20 cm (11.4 by 7.9 inches) and weighing 6.5 kg, it is the largest soft-shell egg ever discovered and the second-largest egg of any known animal. Although the elephant bird egg is slightly larger, its eggshell is roughly five times thicker. University of Texas at Austin paleontologist Lucas Legendre and his colleagues from the United States and Chile think that Antarcticoolithus bradyi was laid by a...

    Named Kampecaris obanensis, the prehistoric millipede lived during the Silurian period, about 425 million years ago. The ancient creature was a small (2-3 cm in length), short-bodied animal with three recognizable sections. It likely lived near a lake in a semi-arid forested environment and ate decomposing plants. Its fossilized remains were unearthed on the island of Kerrera in the Scottish Inner Hebrides. The specimen is about 75 million years younger than the age other paleontologists have estimated the oldest millipede to be using a technique known as molecular clock dating. The oldest fossil of a land-dwelling, stemmed plant, Cooksonia, has...
