Fossil footprints reveal existence of big early dinosaur predator

By On October 31, 2017

WASHINGTON (Reuters) - A trail of fossilized three-toed footprints that measure nearly two feet (57 cm) long shows that a huge meat-eating dinosaur stalked southern Africa 200 million years ago at a time when most carnivorous dinosaurs were modest-sized beasts.

Scientists on Thursday described the footprints from an ancient river bank in Lesotho, and estimated that the dinosaur, which they named Kayentapus ambrokholohali, was about 30 feet (9 meters) long.

No fossilized bones were found, but the footprints alone showed a lot about the animal. The scientists concluded it was a large theropod -- the two-legged carnivorous dinosaur group that included later giants like Tyrannosaurus and Giganotosaurus -- but that it was more lightly built than those brutes. The theropod group also gave rise to birds.

Kayentapus lived early in the Jurassic Period, shortly after a mass extinction that doomed other large reptilian terrestrial predators that lived in the preceding Triassic Period, when dinosaurs first appeared.

“Our finding corroborates the hypothesis that theropods reached a great size relatively early in the course of their evolution, but apparently not before the Triassic-Jurassic boundary,” said paleontologist Fabien Knoll, of the Dinopolis Foundation in Spain and the University of Manchester in Britain.

There are no skeletal fossils of meat-eating dinosaurs this large so early in the dinosaur evolutionary history. It lived on the ancient southern hemisphere super-continent of Gondwana.

There are other fossilized footprints from Poland that indicate a similar-sized theropod inhabited the northern super-continent of Laurasia around the same time.

Theropods of similar size do not appear in the fossil record until 30 million years later, Knoll said.

The footprints were found on what was once a river bank, bearing telltale ripple marks and desiccation cracks.

“It is the first evidence of an extremely large meat-eating animal roaming a landscape otherwise dominated by a variety of herbivorous, omnivorous and much-smaller carnivorous dinosaurs,” added paleontologist Lara Sciscio of the University of Cape Town in South Africa.

The research was published on Wednesday in the journal PLOS ONE.

In separate research, other scientists on Thursday described another new dinosaur, a plant-eater called Matheronodon provincialis, that lived 70 million years ago. Its fossils were unearthed in southern France.

Matheronodon is distinctive for its large teeth with a chisel-like cutting edge that provided a powerful shearing action like scissors to eat tough vegetation, said paleontologist Pascal Godefroit of the Royal Belgian Institute of Natural Sciences in Brussels.

That research was published in the journal Scientific Reports.

NASA Discovers our universe is been "hunted" by an unknown

Explanation: Is our universe haunted? It might look that way on this dark matter map. The gravity of unseen dark matter is the leading explanation for why galaxies rotate so fast, why galaxies orbit clusters so fast, why gravitational lenses so strongly deflect light, and why visible matter is distributed as it is both in the local universe and on the cosmic microwave background. The featured image from the American Museum of Natural History’s Hayden Planetarium Space Show Dark Universe highlights one example of how pervasive dark matter might haunt our universe. In this frame from a detailed computer simulation, complex filaments of dark matter, shown in black, are strewn about the universe like spider webs, while the relatively rare clumps of familiar baryonic matter are colored orange. These simulations are good statistical matches to astronomical observations. In what is perhaps a scarier turn of events, dark matter -- although quite strange and in an unknown form -- is no longer thought to be the strangest source of gravity in the universe. That honor now falls to dark energy, a more uniform source of repulsive gravity that seems to now dominate the expansion of the entire universe.

creatures you don't believe that exit

By On October 01, 2017

One of the creatures you don't believe that do exist is the mami this creature has existed

long ago and some people still think they are ferry teals but looking at this image i think it should give you the scope that this creatures are real and not ferry teals like you where told one of this images the one on gray is an archaeological findings and the other is a dead mami discovered at the sea side no one knows what killed the young mami, many say it was killed by a shark or lager sea creature above.
