Jade Simon, a professor at Laramie County Community College, was a critical part of a paleontologist team that discovered a new species of meat-eating dinosaur that’s best described as a giant 170-pound chicken from hell. A new prehistoric avian dinosaur, similar to this one, has been discovered. A Wyoming paleontologist helped verify it. (Cowboy State Daily Illustration) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When paleontologists found a drumstick from what can best be described as a 68-million-year-old chicken from hell, they needed expert on prehistoric hell chickens to confirm it as a new species. And they found her in Wyoming at Laramie County Community College....

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...

This video delves into the intriguing tale of Andrew Sarkus Mongali Enus, the largest land predator ever unearthed. Its discovery, nearly a century past, during an expedition in Mongolia, unveiled a creature of formidable proportions. Initially pegged as a member of the Mesonychids, a diverse group of mammals spanning small to large sizes, further scrutiny four decades later revealed Andrew Sarkus's true kinship with the Uintatheres, colloquially dubbed "hell pigs." The enigmatic nature of Andrew Sarkus is compounded by its solitary status within the Andrew Sids group, making it a challenge to reconstruct its full anatomical profile. Clad in fur...

Straight-tusked elephants were the largest land mammals of the Pleistocene epoch, present in Europe and western Asia between 800,000 and 100,000 years ago.These animals had a very wide head and extremely long tusks, and were roughly three times larger than that of living Asian elephants, twice that of African ones, and also much larger than woolly mammoths.Estimates of maximum shoulder height vary from 3 to 4.2 m (10-14 feet) and body mass from 4.5 to 13 tons for females and males, respectively."We have estimated that the meat and fat supplied by the body of an adult Palaeoloxodon antiquus bull would...

The face of an eight-year-old Neanderthal boy who died more than 30,000 years ago has been reconstructed by scientists who used a skull initially found in the Teshik-Tash cave in Uzbekistan in 1938. The portrait is the first three-dimensional restoration of a Neanderthal skull fossil, which reveals the young boy had a small, turned-up nose that sunk into his face. The fossil is the first Neanderthal fossil discovered in Asia and the only complete Asian Neanderthal skull fossil preserved so far....

Around 120 million years ago, four-winged dinosaurs roughly the size of crows called Microraptors stalked the ancient woodlands of what is now China.While researchers have studied several Microraptor specimens, there's still a lot we don't know about these feathered bird-like creatures – including what and how they ate.Now an incredibly rare fossil has revealed the preserved final meal of one individual: and unexpectedly, it was a mammal...The first Microraptor fossil was found in Liaoning, China, in 2000. There are three known species, which lived in the early Cretacious period, and the fossil in question belongs to Microraptor zhaoianus...The Microraptors were...

On the small island of Minorca, a popular European tourist destination, researchers have unearthed an enormous fossil rabbit skeleton. A recent study published in the Journal of Vertebrate Paleontology highlights this new find off the coast of Spain. This massive rabbit, aptly named the Minorcan King of the Rabbits (Nuralagus rex), weighed in at 12 kg (26.4 lbs)! — approximately ten times the size of its extinct mainland cousin (Alilepus sp.) and six times the size of the living European rabbit, Oryctolagus cuniculus...The rabbit king lived approximately 3-5 million years ago and may be one of the oldest known cases...

We know that colliding two particles in empty space can sometimes cause additional particles to emerge. There are even theories that a strong enough electromagnetic field could create matter and antimatter out of nothing itself. Big Think reports, in early 2022, a group of researchers created strong enough electric fields in their laboratory to level the unique properties of a material known as graphene. With these fields, the researchers were able to enable the spontaneous creation of particle-antiparticle pairs from nothing at all. This proved that creating matter from nothing is indeed possible, a theory first proposed by Julian Schwinger,...

The fossilized skeleton of a T. rex relative that roamed the earth about 76 million years ago will be auctioned in New York this month, Sotheby’s announced Tuesday. The Gorgosaurus skeleton will highlight Sotheby’s natural history auction on July 28, the auction house said. The Gorgosaurus was an apex carnivore that lived in what is now the western United States and Canada during the late Cretaceous Period. It predated its relative the Tyrannosaurus rex by 10 million years. The specimen being sold was discovered in 2018 in the Judith River Formation near Havre, Montana, Sotheby’s said. It measures nearly 10...

“Genyornis was two meters tall and 200 kilos. We don’t know exactly what it would have looked like because it’s been dead for a while and there are few skeletal remains available. It was certainly a flightless bird with some characteristics shared with ostriches, like the big chest and small wings, but it would have looked more like a big goose or duck,” The evidence that humans were eating these large eggs comes from burnt eggshells found among the remains of ancient cultures. Scientists studying these sites find two different types of eggshells, one of which comes from emus and...

Proteins extracted from fragments of prehistoric eggshell found in the Australian sands confirm that the continent’s earliest humans consumed the eggs of a two-metre tall bird that disappeared into extinction over 47,000 years ago.Burn marks discovered on scraps of ancient shell several years ago suggested the first Australians cooked and ate large eggs from a long-extinct bird – leading to fierce debate over the species that laid them.Now, an international team led by scientists from the universities of Cambridge and Turin have placed the animal on the evolutionary tree by comparing the protein sequences from powdered egg fossils to those...

Entombed in a limestone shelf of South Africa’s Rising Star Cave, the fragmented skull of a Homo naledi child has suggested that the prehistoric species may have been more similar to modern humans than previously thought. Two new studies, published this week in the journal PaleoAnthropology, have revealed new details about the mysterious Homo naledi people, based on a set of fossils first discovered in 2017, which are believed to be that of a young Homo naledi of 4- to 6-years-old. An international team of researchers has estimated the child would have lived between 236,000 and 335,000 years ago, before...

A Caudipteryx zoui fossil cast. (Daderot/Wikimedia Commons/CC0 1.0) The remnants of DNA may lurk in 125 million-year-old dinosaur fossils found in China. If the microscopic structures are indeed DNA, they would be the oldest recorded preservation of chromosome material in a vertebrate fossil. DNA is coiled inside chromosomes within a cell's nucleus. Researchers have reported possible cell nucleus structures in fossils of plants and algae dating back millions of years. Scientists have even suggested that a set of microfossils from 540 million years ago might hold preserved nuclei. These claims are often controversial, because it can be hard to distinguish...

Mammals from mice to monkeys have tails. But humans and our cousins the great apes lack them. Now, Researchers may have unearthed a simple genetic change that led to our abbreviated back end: an itinerant piece of DNA that leapt into a new chromosomal home and changed how great apes make a key developmental protein. The finding also suggests the genetic shift came with a less visible and more dangerous effect: a higher risk of birth defects involving the developing spinal cord. The work not only addresses an “inherently interesting question about what makes us human,” says Hopi Hoekstra, an...

The study, led by scientists at the University of Bath and including collaborators from Bristol, Cambridge and Germany, used fossils and analysed genetic differences between modern snakes to reconstruct snake evolution. The analyses helped to pinpoint the time that modern snakes evolved.Their results show that all living snakes trace back to just a handful of species that survived the asteroid impact 66 million years ago, the same extinction that wiped out the dinosaurs.The authors argue that the ability of snakes to shelter underground and go for long periods without food helped them survive the destructive effects of the impact. In...

Close-up of the skin, with ridges marked. (Hendrick and Bell, Cretaceous Research, 2021 https://www.sciencedirect.com/science/article/abs/pii/S0195667121002421#fig3 The outer parts of long-dead creatures don't easily make it into the fossil record. That's why this incredibly well-preserved skin of an iconic carnivorous dinosaur is such a treat – a new analysis reveals a complex coat of scales, studs, thorns, bumps and wrinkles. The remains of this bizarre-looking predator, known as the horned abelisaurid (Carnotaurus sastrei), were first discovered in Patagonia in 1984. At the time, it was the first meat-eating dinosaur ever found with fossilized skin, and the exquisite impressions covered nearly every part...

Lepidosaurs are scaled reptiles such as lizards, snakes, and New Zealand's tuatara, which together represent the most diverse group of land-living vertebrates alive today. Yet little is known about their early origins compared to the other arms of reptilian evolution which produced crocodiles, birds, and turtles... The fossil, found in Ischigualasto Provincial Park in northwest Argentina, is about 11 million years younger than the oldest known lepidosaurs from Europe, but one of the best-preserved specimens of its kind, which means the team can have more confidence in their analyses... It's a lucky find, especially considering the origins of lepidosaurs have...

A total of 2.5 billion Tyrannosaurus rex probably existed during the lifespan of the species, researchers have calculated – suggesting that very few survived as fossils. Charles Marshall at the University of California, Berkeley, and his colleagues used body mass and population density to estimate how many T. rex once lived. Larger animals tend to have a larger individual range, because they need more food to support their body mass than smaller animals, meaning body mass is inversely correlated with population density – a rule known as Damuth’s law. Previous analysis of T. rex fossils shows that the average body...

In the rocky terrain of the Whitmore mountain range in Antarctica, there have been found fossilized skeletal remains of what seems to be extremely small humans. Interestingly enough, this discovery was made while yours truly was in Antarctica on assignment for The National Reporter to debunk a ridiculous tabloid story about a UFO base in the area.

What happened to the wood that made it that way in the beautiful petrified trees in the forests of Arizona? They believe that petrified wood is so old that in the prehistoric period it has emerged. But do you know how petrified wood was made? This guide will show you how. What is petrified wood and how is it formed? Fossil wood is considered to have grown when the material of the plant is buried by sediment. When the wood is buried deep in the muck, it is protected from decay caused by exposure to oxygen and organisms.
