We don’t even know if they were plants or animals.
The 245-million-year-old fossils overturns the established view that early dino relatives were the size of a chicken and feeble.
Geoscientists working in South America have uncovered an ancient berry.
Bones to stones.
Paleontologists have identified an ancient hyena-like canine that occupied eastern North America approximately 12 million years ago. The coyote-sized dog had a massive jaw which scientists say it used to crush bones.
Sauropods, or some titanosaurs at least, were not the best parents. A recent analysis of juvenile fossils belonging to a titanosaur species called Rapetosaurus krausei suggests babies were left to fend for themselves and find food since they hatched, with little if any weaning.
It was a finding that sent ripples throughout the entire paleontology community. Met with heavy criticism, the authors are now vindicated.
Researchers have found new fauna in northern Brazil, in what used to be the continent of Gondwana.
Tyrannosaurus was one of the fiercest land predators ever, despite claims that the dinosaur was mostly a scavenger. While this is true to a degree, T-Rex was most definitely a hunter at heart even though the predator might have munched on a carcass or two from time to time. Apparently, the dinosaur even ate its own kind, a new study suggests.
This bizarre creature looks like a cross between a scorpion and a boat, which is pretty accurate considering it was actually as big as a boat. Pentecopterus decorahensis, named after the ancient Greek warship, likely dominated the Ordovician ocean waters some 460 to 248 million years ago, paleontologists say. Sporting a thick head shield, a paddle for a tail, large grasping limbs and 1.7 meters in length (5.5 feet), this sea beast was a force to be reckoned with.
A novel analysis reveals T-rex and other theropods – the top land predators that dominated the planet for no less than 165 million years – had teeth of unrivaled complexity. The long and powerful teeth were serrated like steak knives to disembowel prey easily, while on the inside tissue supported the teeth for maximum resistance against the powerful sheering stress which followed each bite.
Traces of soft tissue and red blood cells were discovered by accident by a team of paleontologists and biologists while they were playing around in the lab with so-called “crap” fossils dug up more than 100 years ago in Canada. Usually, museum curators are very proud and picky about the works they display or hold in storage, and any analysis that involves breaking or sectioning a fossil is most often than not strictly forbidden. But these fossils – like a claw from a meat-eating therapod, the limb from a duck-billed dinosaur and even the toe of a triceratops-like animal – were fragments in poor conditions that nobody really cared about. One man’s trash, another man’s treasure.
Each year, hundreds of millions people fly by plane to meet family, do business or travel for leisure. Quite a feat, considering humans don’t have any wings. Like all advanced technology we have at our disposal today, flying is also taken for granted. In the early days, however, just getting a few feet off the ground for a couple of seconds was considered a triumph. Like human pioneering flight, nature also had to experiment a lot before flying creatures could evolve. One newly discovered dinosaur species fits well into this story. Unearthed in 160 million year old sediments in China, this queer dinosaur strangely had bat-like wings. It’s uncertain however if it was able to fly or even glide, owing to the degraded state of the fossil records. One thing’s for sure, it makes the evolution of flight much more interesting to study.
Just like Pluto, the iconic dinosaur genus was demoted decades ago and classified under another sauropod genus. But a more sophisticated taxonomy recently published by researchers in the UK and Portugal warrants a revisit of the shelved, but never forgotten Brontosaurus.
Long before T-rex claimed the top dog spot among terrestrial predators, a vicious crocodile ancestor that walked on its hind legs was at the top of the food chain during the Triassic. The fossils of the Carnufex carolinensis, also known as the the “Carolina Butcher,” were discovered decades ago in the Pekin Formation, a geological formation in North Carolina’s Chatham County. It was only recently that researchers reanalyzed the fossils and concluded they were dealing with an all new predator that roamed the Earth several million years before dinosaurs were even around.
Paleontologists diving beneath the surface of a water-filled cave in Madagascar made a monumental find: a graveyard filled with the bones of a wide variety of species,some very rare, other extinct for hundreds, if not thousands of years. Some of the remains that dot the bottom of the Aven Cave in Tsimanampetsotse National Park include those of the extinct elephant bird, a flightless giant similar to an ostrich, but most bones belong to the long-lost giant lemurs.
Based on fossil evidence and genome analysis, scientists know that the two groups diverged from a common ancestor around 420 million years ago, but we’ve yet to find actual fossil of it. Things are shaping up though after paleontologists have identified an Early Devonian fish from Siberia, approximately 415 million years old, which bears features of both classes.
It’s very small and incredibly old – scientists have found the egg of a 240 million year old parasite – a pinworm, to be more precise. It’s the oldest pinworm ever found, and one of the oldest evidences of parasitism ever found. The pinworm, also known as threadworm, is a parasitic intestinal worm, pretty common in humans. The pinworm has
Dr Nick Longrich from Bath University was studying bones from two horned dinosaurs from the ceratopsian family (related to Triceratops), when he discovered that the two were actually previously unknown species. The findings highlight that dinosaurs in area were more diverse than previously thought, and they also show that sometimes, museum archives can yield surprising information. “We thought we had discovered most
It was about as big as T-Rex, but not quite as fit – new fossils have revealed that Deinocheirus mirificus had quite a beer belly. “This is an entirely new body plan” for such dinosaurs, says Stephen Brusatte, a vertebrate palaeontologist at the University of Edinburgh, UK. Indeed, few scientists would have imagined such a scientific appearance. The first fossils of Deinocheirus mirificus (which means ‘unusual
