  • Microbes make tubular microtunnels on Earth and perhaps on Mars

    Science Daily ^ | 5/4/2016 | Matthew P.C. Nikitczuk
    Tubular microtunnels believed to be the trace fossils formed by microbes inhabiting volcanic rock interiors have only been reported in oceanic and subglacial settings. This is the first observation of such features in basaltic volcanic glass erupted in a continental lake environment, the Fort Rock volcanic field. As a result, the record of subsurface microbial activity in the form of endolithic microborings is prospectively expanded. Our understanding of the range of environments and conditions that microtunnels can form in is enhanced along with our knowledge of potentially habitable environments on Earth and beyond. The Fort Rock volcanic field has analogous...

    Radiometric backflip: Bird footprints overturn ‘dating certainty’ by Jonathan O'Brien Using well-known radioisotope technology, scientists dated the Santo Domingo rock formation in Argentina at 212 million years old. This happened to agree well with a nearby geologic formation that was also radiometrically dated.1 The radiometric date of the Santo Domingo formation also agreed with the dating based on fossil wood found entombed in the rock. This wood came from an extinct species of tree conventionally believed to have existed around 200 million years ago. Well-preserved and abundant tracks were also found in the rock, similar in appearance to bird tracks....

    A 300 million year-old fossil mystery has been solved by a research team led by the University of Leicester, which has identified that the ancient 'Tully Monster' was a vertebrate -- due to the unique characteristics of its eyes. Tullimonstrum gregarium or as it is more commonly known the 'Tully Monster', found only in coal quarries in Illinois, Northern America, is known to many Americans because its alien-like image can be seen on the sides of large U-haul™ trailers which ply the freeways. Despite being an iconic image -- a fossil with a striped body, large tail, a pair of...

    New research reveals that the limbs of the earliest four-legged vertebrates, dating back more than 360 million years ago, were no more structurally diverse than the fins of their aquatic ancestors. The new finding overturns long-held views that the origin of vertebrates with legs (known as tetrapods) triggered an increase in the anatomical diversity of their skeletons. The research was carried out by Dr Marcello Ruta from the School of Life Sciences at the University of Lincoln and Professor Matthew Wills from the Milner Centre for Evolution at the University of Bath in the UK.

    Most recent dating places one wave of human dispersal out of Africa into southeastern Spain at almost one million years ago. Using state-of-the-art dating methodologies, a team of scientists have obtained or confirmed a date range between .9 and .85 Mya (million years ago) as a time when a species of Old World monkey (Theropithecus) and an early species of human occupied the cave site of Cueva Victoria in southeastern Spain. It is a location not far from where many scientists have hypothesized that humans may have crossed over into Europe from North Africa through the Strait of Gibraltar at...

    Science Daily ^ | 12/11/2015 | American Museum of Natural History
    New research led by the American Museum of Natural History reveals that the evolution of modern birds was greatly shaped by the history of our planet's geography and climate. The DNA-based work, published today in the journal Science Advances, finds that birds arose in what is now South America around 90 million years ago, and radiated extensively around the time of the Cretaceous-Paleogene extinction event that killed off the non-avian dinosaurs. The new research suggests that birds in South America survived this event and then started moving to other parts of the world via multiple land bridges while diversifying during...

Palaeomerycids, now extinct, were strange three-horned Eurasian Miocene ruminants known through fossils from Spain to China. In this article, the authors classify the palaeomerycid to their clade based on shared characteristics with the best-known species of the group and reassess their phylogenetic position among ruminants, which is currently disputed.

    Pre-Flood Human Fossils Revisited by Brian Thomas, M.S. * Evidence for Creation Where are the fossils from the people who lived before the Flood? A 1992 ICR article supplied seven responses to this question.1 Land animals and humans have a low fossilization potential. We would expect few fossils from them. If the Flood buried a multitude of people and distributed their bodies among the world’s sedimentary rocks, finding even one human fossil in such a vast area would be unlikely. Underwater mudflows during the Flood would have ground human bones to powder. Floodwaters receding off continents might have likewise pulverized...

    The release of Jurassic World has reignited our love for palaeontology. Many of us share a longing to understand the dinosaurs that roamed the Earth long before we arrived. But palaeontology is a discipline much broader than this. Dinosaurs dominated the land for 135 million years, but what happened during the rest of the Earth's 4.6 billion-year history? The role of palaeontologists past and present has been to unravel the mysteries of life on Earth, and in doing so they've found a lot more than just dinosaur bones. -------------------------------------------------------------------------------------------------------------------------------------------- 1.

A brief hike nearly to the top of a shorter ridge ends at the quarry, where picks and hammers have chopped out a ledge of sorts in the slate-grey hillside. Sometime about 220 million years ago, a meandering stream flowed here and plants grew along its banks. Something, as yet unknown, caused sediment to flood the area rapidly, which helped preserve the plants. Gulbranson splits open a grey slab...

Andrew Dialla, a resident of Pangnirtung, Nunavut, says he found the skull protruding from the frozen tundra during a walk near the shore with his daughter about a month ago. The horned skull is about the size of a man's fist. It resembles a baby caribou skull, except at that age, a caribou wouldn't have antlers, researchers and elders have pointed...

    Original soft-tissue fossils continue to challenge mainstream understanding of how and when fossils formed. Secular researchers described dozens of them over the years, from mummified skin and dried red blood to still-purple retinas, and they assign them ages of tens of millions of years. However, the science of tissue decay clearly does not permit these long ages. For example, lab bench tests that accelerate tissue decay under high temperatures place a maximum age of fewer than one million years on some of the most resilient proteins, assuming the fossil proteins were kept cold and sterile during the entire process. These...

Within a fortnight the sea tides that exposed the prints last May destroyed them, leaving only casts and 3D images made through photogrammetry – by stitching together hundreds of photographs – as evidence that a little group from a long-extinct early human species had passed that way. They walked through a startlingly different landscape from today’s, along the estuary of what may have...

The research is the first independent assessment of the claims made in a scientific paper and a television documentary earlier this year. Dr Erik Seiffert says that Ida belonged to a group more closely linked to lemurs than to monkeys, apes or us. His team's conclusions come from an analysis of another fossil primate. The newly described animal - known as Afradapis longicristatus - lived some 37 million years ago in northern Egypt, during the...

    The brains of chimpanzees show a number of similarities to human brains, the results of two new studies suggest. Findings published in the December issue ofBehavioral Neuroscience indicate that the animals have differences between the right and left sides of their brains in much the same way that humans do. In addition, it appears that the neurological basis for handedness is not unique to our species. Hani D.

    Despite decades of study, geneticists don't know what makes humans human. Language, long arms, and tree-climbing prowess aside, humans and our kissing cousins, chimpanzees, share practically all of our DNA. Genomic studies have suggested that the regulation of genes, rather than the genes themselves, set the two primate species apart. But genes are still an important part of the story, says Michele Cargill, a geneticist at Celera Diagnostics in Alameda, California. She and her colleagues found key differences between chimp and human genome coding sequences, differences that propelled human evolution and sometimes lead to genetic diseases. Genes for olfaction and...

    Why the Y chromosome is a hotbed for evolution Mark Henderson, Science Editor The Y chromosome is often seen as the rotten corner of the human genome — a place of evolutionary decline that is slowly decaying and threatening the end of man. Reports of its imminent demise, however, have been exaggerated. Research has indicated that, far from stagnating, the male chromosome is a hotspot of evolution that is changing more quickly than any other part of humanity’s genetic code. In most mammals the sex of offspring is determined by X and Y chromosomes. Females have two Xs, males have...

Now the researchers have decoded more than half of the Y chromosomes, or 12.7 million base pairs, of man's closest living relative.

    Since the human-chimp split about 6 million years ago, chimpanzee genes can be said to have evolved more than human genes, a new study suggests. The results, detailed online this week in the Proceedings of the National Academy of Sciences, contradict the conventional wisdom that humans are the result of a high degree of genetic selection, evidenced by our relatively large brains, cognitive abilities and bi-pedalism. Jianzhi Zhang of the University of Michigan and his colleagues analyzed strings of DNA from nearly 14,000 protein-coding genes shared by chimps and humans.

The Triassic period saw the re-establishment of ecosystems after the Permian mass extinction. The fossils represent new evidence that marine ecosystems re-established more quickly than previously thought. The Permian mass extinction had a bigger impact on the earth's ecological systems than any other mass extinction, wiping out 90-95% of marine species. Previous studies have suggested that Triassic marine life developed more quickly than was once thought and that marine ecosystems were re-established more rapidly than terrestrial ecosystems...

    The behaviour of an ancient horseshoe crab in its final moments before death has been captured in the fossil record. A 9.7m-long trackway was created around 150 million years ago when a horseshoe crab fell into a lagoon. The find is of interest because the fossil of the animal itself is present at the end of the trackway, where the animal died. The research appears in the journal Ichnos. The fossil trackway of the animal's last moments - known as a mortichnia, or death march - was discovered in the lithographic limestone of Bavaria in Germany in 2002, where spectacular...

    These 230-million-year-old bugs preserved in amber are the oldest yet An international team of scientists working in Italy have found the oldest samples of arthropods preserved in amber — a finding that is 100 million years older than previous fossilized samples. The insects, a fly and two mites, are the first ever to be discovered from the Triassic era. The group's findings will help biologists gain a better evolutionary understanding of these organisms and the time periods within which they developed. Amber droplets can be a goldmine for paleontologists. Even a millimeter sized droplet can contain extremely well preserved specimens...

    Famed explorer Robert Ballard's expedition over the Eratosthenes Seamount is currently collecting images during sweeps of the area using the latest technology to explore the sea floor some 70 miles off the island. After two days of exploring, the team's underwater robots, operating at 800 to 1,000 metres, yesterday reached the summit of the Eratosthenes, going over terrain from a previous sweep and then turned west to head to unexplored territory to the west. On Friday night they came across what appeared to be fossilised rib bones commentators suggested might have come from a whale, perhaps even 40,000 years old......

    Monster titanoboa snake invades New York New York commuters arriving at Grand Central Station were greeted by a monstrous sight: a 48-foot-long, 2,500-pound titanoboa snake. The good news: It's not alive. Anymore. But the full-scale replica of the reptile -- which made its first appearance at the commuter hub -- is intended, as Smithsonian spokesperson Randall Kremer happily admitted, to "scare the daylights out of people" -- actually has a higher calling: to "communicate science to a lot of people." The scientifically scary-accurate model will go a long way toward that: If this snake slithered by you, it would be...
  • What Did Velociraptor Have For Dinner? Raptor Skeleton Discovered With Bones In Its Gut

    What did Velociraptor have for dinner? Raptor skeleton discovered with bones in its gut If you lie awake at night wondering Velociraptor's favorite food was (and whether it tastes much like human flesh), you're in luck. For the first time, a Velociraptor skeleton has been observed with its last supper still filling its guts, and this little guy feasted on long-dead pterosaur. Paleontologist David Hone has published a new paper describing his findings in Palaeogeography, Palaeoclimatology, Palaeoecology, but for those who don't want to breach the paywall, he's also explaining them on his blog. This especially well preserved specimen was...

    EDMONTON — University of Alberta scientist Duane Froese was on sabbatical last summer when he received a call from a Yukon miner who wanted to give him the heads-up about a site he planned to excavate. Like most Klondike miners, Tony Beets is a character. He’s tall, bushy-haired, drives fast and uses colourful language. But he’d also been incredibly helpful over the years, moving in heavy equipment for scientists such as Froese, exposing layers of ancient permafrost that yielded the frozen bones of woolly mammoths, scimitar cats, short-faced bears and other animals that lived in this part of the world...
  • Perfect fossil could be most complete dinosaur ever

    Dinosaur fossils don't come much more impressive than this. With 98 per cent of its skeleton preserved, this young predatory theropod from southern Germany may be the most complete dinosaur ever found. Oliver Rauhut, curator of the Bavarian State Collection for Palaeontology and Geology in Munich, announced the find yesterday. Although Chinese bird and dinosaur fossils are famed for delicate details such as their feathers, they don't match this 72-centimetre-long theropod in terms of clarity and completeness of preservation. The young dinosaur has been dated at 135 million years old, putting it in the early Cretaceous, but it has yet...

Credit: David Wacey/University of Western Australia When Martin Brasier discovered what looked like fossil cells in between the cemented sand grains of an ancient beach in Western Australia, he knew he had his work cut out for him. One of the biggest challenges for geologists is deciding when a fossil is really a fossil, particularly when it comes to early life. There are no bones to go by, and the mineralized spheres representing simple cells and sometimes filaments could easily...

    The Outback Gondwana Foundation (OGF) has recently completed another two week dinosaur dig near Eromanga and they've made some exciting new discoveries. Mackenzie is the Foundation's chair and said exciting discoveries were unearthed in the lab and at the dig site. In the lab it was 'Sid', a new plant-eating dinosaur that was identified. "While we were working on some of the Cooper material we actually discovered there was another dinosaur there as well," said Mr Mackenzie. The new dinosaur has been tagged 'Sid' after Sir Sidney Kidman and that's because Plevna Downs is in the Cooper Creek area and...

    A Suncor oilsands worker near Fort McMurray, Alta., has unearthed a rare dinosaur fossil that could be 110 million years old. On Monday, shovel operator Shawn Funk noticed a large lump of dirt with an odd texture and a diamond pattern in a shovel-load of material. He shut down the shovel, and together he and supervisor Michel Gratton sent photos of the find to the Royal Tyrrell Museum in Drumheller, Alta. The find intrigued experts enough that the museum sent a scientist and a technician up to Fort McMurray two days later. Curator Donald Henderson believes the completely intact dinosaur...

    'Thunder-Thighs' Dinosaur Discovered: Brontomerus May Have Used Powerful Thigh Muscles to Kick Predators ScienceDaily (Feb. 23, 2011) — A new dinosaur named Brontomerus mcintoshi, or "thunder-thighs" after its enormously powerful thigh muscles, has been discovered in Utah, USA. The new species is described in a paper recently published in the journal Acta Palaeontologica Polonica by an international team of scientists from the UK and the US. A member of the long-necked sauropod group of dinosaurs which includes Diplodocus and Brachiosaurus, Brontomerus may have used its powerful thighs as a weapon to kick predators, or to help travel over rough, hilly...

    T. Rex More Hyena Than Lion: Tyrannosaurus Rex Was Opportunistic Feeder, Not Top Predator, Paleontologists Say ScienceDaily (Feb. 22, 2011) — The ferocious Tyrannosaurus rex has been depicted as the top dog of the Cretaceous, ruthlessly stalking herds of duck-billed dinosaurs and claiming the role of apex predator, much as the lion reigns supreme in the African veld. But a new census of all dinosaur skeletons unearthed over a large area of eastern Montana shows that Tyrannosaurus was too numerous to have subsisted solely on the dinosaurs it tracked and killed with its scythe-like teeth. Instead, argue paleontologists John "Jack"...
