They probably appeared in Poland approximately 300,000 years ago. The oldest stone tools they used, discovered on the Vistula, are over 200,000 years old, and the remains are over 100,000 years old. "On the bank of the river in Pietraszyno, we discovered an unprecedented amount of flint products - 17,000 - abandoned by Neanderthals approximately 60,000 years ago" - says Dr. Andrzej Wisniewski from the Institute of Archaeology, University of Wroclaw. Since 2018, the researcher has been conducting joint excavations with researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig in the framework of a National Science Centre...

Neanderthals are often depicted as having straight spines and poor posture. However, these prehistoric humans were more similar to us than many assume. University of Zurich researchers have shown that Neanderthals walked upright just like modern humans - thanks to a virtual reconstruction of the pelvis and spine of a very well-preserved Neanderthal skeleton found in France... Since the 1950s, scientists have known that the image of the Neanderthal as a hunched over caveman is not an accurate one. Their similarities to ourselves - both in evolutionary and behavioral terms - have also long been known, but in recent years...

A new oviraptorosaur species from the Late Cretaceous was discovered in Mongolia... Oviraptorosaurs were a diverse group of feathered, bird-like dinosaurs from the Cretaceous of Asia and North America. Despite the abundance of nearly complete oviraptorosaur skeletons discovered in southern China and Mongolia, the diet and feeding strategies of these toothless dinosaurs are still unclear. In this study, Lee and colleagues described an incomplete skeleton of an oviraptorosaur found in the Nemegt Formation of the Gobi desert of Mongolia. The new species, named Gobiraptor minutus, can be distinguished from other oviraptorosaurs in having unusual thickened jaws. This unique morphology suggests...

The prestigious international journal Quaternary Science Reviews has just published a paper which has involved the participation of Gibraltarian scientists from the Gibraltar National Museum alongside colleagues from Spain, Portugal and Japan. The results which have been published come from an area of the Catalan Bay Sand Dune. This work started ten years ago, when the first dates using the OSL method were obtained. It is then that the first traces of footprints left by vertebrates were found. In subsequent years the successive natural collapse of sand has revealed further material and has permitted a detailed study including new dates....

More than 3.8 billion years ago, in a time period called the Hadean eon, our planet Earth was constantly bombarded by asteroids, which caused the large-scale melting of its surface rocks. Most of these surface rocks were basalts, and the asteroid impacts produced large pools of superheated impact melt of such composition. These basaltic pools were tens of kilometres thick, and thousands of kilometres in diameter. “If you want to get an idea of what the surface of Earth looked like at that time, you can just look at the surface of the Moon which is covered by a vast...

Hagfish Haunts Darwin A zombie hagfish rises from the dead, and scares Darwin from two directions. January 24, 2019 | David F. Coppedge Hagfish are eel-like fish that look like creatures from a horror movie. Their tapir-like snouts are scary enough, but when threatened, they have a unique weapon: slime! They can spread a net of sticky slime around them that can clog the gills of an attacker. And they have been doing this for at least 100 million Darwin Years, perhaps 300 million.

It turns out that our galaxy looks the way it does today thanks to a run-in with something called the 'Gaia Sausage'. As greasy as space is, we're not talking cosmic processed foods here. Rather, astronomers have found signs that a small galaxy smashed into the Milky Way billions of years ago, leaving behind a mess of stars with some rather unusual orbits. So, what makes this cosmic object a 'sausage'? Cambridge University astronomer Wyn Evans says it all came down to the paths of the stars following the impact... Collisions between galaxies aren't all that unusual, and the Milky...

Just like the modern platypus, this 250-million-year-old, Triassic-age marine reptile likely used its cartilaginous bill to discover and seize its next meal, a new study finds. "This animal had unusually small eyes for the body, only rivaled by some living animals that rely on senses other than vision and feed in the dusk or darkness — for example some shrews, badgers and the duck-billed platypus," said study lead researcher Ryosuke Motani, a paleobiologist at the University of California, Davis. "So, it most likely used tactile senses [with its] platypus-like bill to detect prey in the dusk or darkness." ..." Previously,...

Paleoanthropology Division Smithsonian Institute 207 Pennsylvania Avenue Washington, DC 20078 Dear Sir: Thank you for your latest submission to the Institute, labeled “ 211-D, layer seven, next to the clothesline post . Hominid skull .” We have given this specimen a careful and detailed examination, and regret to inform you that we disagree with your theory that it represents “conclusive proof of the presence of Early Man in Oklahoma County two million years ago. .” Rather, it appears that what you have found is the head of a Barbie doll, of the variety one of our staff, who has small...

One hundred million years ago, the sky was filled with birds unlike those seen today, many with long, streamerlike tail feathers. Now, paleontologists have found examples of these paired feathers preserved in exquisite detail in 31 pieces of Cretaceous amber from Myanmar. The rare 3D preservation reveals the feathers’ structure is completely different from that of modern feathers—and hints that they may have been defensive decoys to foil predators. Such tail streamers—in some cases longer than the bodies—have been observed in early bird fossils from China for several decades, in particular, the 125-million-year-old Confuciusornis sanctus. They may also be present...

About 2.6 million years ago, an oddly bright light arrived in the prehistoric sky and lingered there for weeks or months. It was a supernova some 150 light years away from Earth. Within a few hundred years, long after the strange light in the sky had dwindled, a tsunami of cosmic energy from that same shattering star explosion could have reached our planet and pummeled the atmosphere, touching off climate change and triggering mass extinctions of large ocean animals, including a shark species that was the size of a school bus. The effects of such a supernova—and possibly more than...

While already known that giraffes display preferred choices of companion within their social group, until now it has not been clear what drives these and whether these choices are just some, or all of the time. University of Bristol researcher Zoe Muller and her colleagues from Switzerland, Kenya, Brazil and the United Kingdom aimed to explore what factors drive specific interactions in giraffes, and whether behavioral state or disturbance by humans and predators had any effect on social relationships “The dynamic nature of animal societies often hides multiple layers of complexity,” Muller said.“Our work highlights the complex and dynamic nature...

A new species of sauropod dinosaur that stretched 39 feet (12 m) from head to tail has been unearthed in Patagonia, ArgentinaDubbed Lavocatisaurus agrioensis, the new dinosaur is thought to have lived approximately 110 million years ago (Cretaceous period).The creature was a type of sauropod, a group of huge plant-eating dinosaurs that includes the largest animals ever to walk the Earth.One adult and two immature specimens of Lavocatisaurus agrioensis were recovered near the locality of Agrio del Medio, a small town in the central part of the province of Neuquén, Patagonia.“We found most of the skull bones of Lavocatisaurus agrioensis:...

We now know what the missing teeth would have looked like at the front of this jaw. Eden, Janine and Jim/CC BY 2.0Until this week, Pachycephalosaurus seemed like a friendly neighborhood herbivore. The scariest thing about these dinosaurs, which have been frequently depicted placidly munching on greenery, was the unique architecture of their skulls: domed, sloping, pointy around the edges, and 10 inches thick. They might have butted heads, but that didn’t make them seem dangerous, exactly.But now, new research presented at a Society of Vertebrate Paleontology conference in Albuquerque, New Mexico, raises the specter that Pachycephalosaurus was a...

The 28 footprints capture an early reptile-like creature’s unusual diagonal gait (Courtesy of Stephen Rowland) Some 310 million years ago, a reptile-like creature with an unusual gait roamed the sandy expanses of the Grand Canyon, leaving a trail of 28 footprints that can still be seen today. As Michael Greshko reports for National Geographic, these unusually well-preserved markers represent the national park’s oldest footfalls—and, if additional analysis links the early reptile to one that left a similar set of prints in Scotland roughly 299 million years ago, the tracks may even earn the distinction of being the oldest of their...

The Three Supernovas By Philip Cottraux Atheists used to believe the universe was eternally pre-existing and static. By rejecting the biblical creation account, they couldn’t accept the idea of a universe that had a beginning. Bertrand Russell, Charles Darwin, and at one time even Einstein labored under this philosophy. The idea of the whole universe condensed to a small state whose expansion was triggered by a colossal explosion was first proposed by a Catholic priest, Georges LeMaitres. The idea seemed so preposterous that astronomer Fred Hoyle first coined the phrase “big bang” as a term of ridicule. But two years...

It is now possible to tell the story of mankind's presence and evolution on the planet by analyzing trends in soil and sediment accumulation of fecal sterols, chemical compounds which are crucial in human physiology. Scientists at Ca' Foscari University of Venice and the Institute for the Dynamics of Environmental Processes of the National Research Council (CNR-IDPA) have identified and dated traces of sterols within the sediments of two New Zealand lakes, thus proving the presence of the Maori people who, starting from around 1280, colonized the two oceanic islands and cleared them of forests in just a few decades...

Zanolli and colleagues examined dental remains from the sites of Fontana Fanuccio, located 50km southeast of Rome, and Visogliano, located 18km northwest of Trieste. At around 450,000 years old, these teeth join a very short list of fossil human remains from Middle Pleistocene Europe. Using micro-CT scanning and detailed morphological analyses, the authors examined the shape and arrangement of tooth tissues and compared them with teeth of other human species. They found that the teeth of both sites share similarities with Neanderthals and are distinct from modern humans. There has been much debate over the identities and relationships of Middle...

Popularized in the hit movie "Jurassic World," the mosasaur has come back to life after an 85 million-year-old fossil of a newborn creature was discovered in Kansas. A "neonate-sized Tylosaurus specimen" (a type of mosasaur), has been identified and examined, with researchers looking at broken bones, including its snout, braincase and upper jaw. "Despite its small size, a suite of cranial characters diagnoses FHSM VP-14845 [the fossil's identification] as a species of Tylosaurus, including the elongate basisphenoid morphology," the study's abstract reads. The creature, which could grow up to 42 feet when it reached adulthood, had an "estimated skull length...
