Scientists have been wondering for years which dinosaur could run the fastest. Now, new simulation models are offering a fresh look at dinosaur speed. This renewed interest has roots in a major discovery from 1964, when paleontologist John Ostrom and his team uncovered Deinonychus—a dinosaur with a lightweight body, long claws, and strong legs. Its features challenged the long-held image of dinosaurs as sluggish reptiles and instead pointed to an active, fast-moving predator. This discovery helped launch what scientists call the “dinosaur renaissance,” a major shift in how experts understood dinosaur behavior. Instead of slow-moving reptiles, some dinosaurs began to...

For years, scientists widely believed that the fossilization process destroyed all original organic molecules, leaving fossils devoid of their original biological material. However, a groundbreaking study led by the University of Liverpool has provided strong evidence that Mesozoic fossils, including dinosaur bones and teeth, still contain preserved organic materials. Using advanced mass spectrometry and other analytical techniques, researchers detected remnants of collagen in the hip bone of an Edmontosaurus, a duck-billed dinosaur. This...

researchers have uncovered a series of massive dinosaur trackways dating back to the Middle Jurassic Period, approximately 166 million years ago. Dubbed a 'dinosaur highway,' the site features footprints from both herbivorous dinosaurs, likely Cetiosaurus and the fearsome carnivore Megalosaurus. The discovery was made at Dewars Farm Quarry in Oxfordshire, England, and includes over 200 footprints spread across five extensive trackways, the longest of which stretches more than 150 meters. ... a skeleton is a record of the animal once it's died. Footprints are quite different in that they are snapshots into the life of an animal .... The overlapping...

In a new study published Thursday in the journal Science, researchers pieced together the chemical identity of the asteroid that fueled the planet’s fifth mass extinction event. Sixty-six million years ago, the story of life on Earth took a dramatic turn when an asteroid collided with what’s now the Yucatán Peninsula in Chicxulub, Mexico. The aftereffects of the collision resulted in the extinction of an estimated 75% of animal species, including most dinosaurs except for birds. But practically nothing of the asteroid itself remains. In a new study published Thursday in the journal Science, researchers pieced together the chemical identity...

Extinct marine lizard the size of an orca with sharp teeth and a strong jaw was a top predator during the dinosaur age. Paleontologists in Morocco have discovered the fossilized remains of a huge, never-before-seen species of marine lizard with "dagger-like" teeth. The reptile was around 26 feet (8 meters) long — about the same length as an orca — and hunted in the Atlantic Ocean off the coast of what is now Africa at the end of the dinosaur age, about 66 million years ago, according to a study published March 1 in the journal Cretaceous Research. The creature...

Paleontologists have uncovered the remains of megaraptor that lived 70 million years ago, making it one of the last carnivorous dinosaur to roam the Earth. Discovered in Argentina, the team found vertebrae, ribs and part of what would have been the dinosaur's chest and shoulder girdle. After a further analysis, they determined the creature was approximately 33 feet in length -the largest megaraptor found to date. Unlike the Tyrannosaurus rex, this lethal dinosaur had extremely long, muscular arms with massive claws at the end that were used to attack prey.

A new dinosaur species, notable for a row of two-foot spines protruding from its neck, has been discovered by scientists in Argentina. Scientists have dubbed the new dinosaur, “Bajadasaurus,” an herbivore that lived 140 million years ago, according to the scientific journal Nature, which first revealed the findings. Its name is an amalgam of Spanish, Greek, and Latin, meaning “lizard from Bajada with forward-bending spines.” The dinosaur's unusual "spines" have fueled a wave of speculation about what purpose they may have served. Pablo Gallina, a paleontologist who first came across a set of its teeth in 2010, said the “long and sharp...

BUENOS AIRES (AFP) - Argentine paleontologists have discovered the largely intact skeleton of a young titanosaurus that lived 71 million years ago. "What's extraordinary about this is that the remains were articulated, as if the animal had fallen or lain down and remained that way. There were no signs that it was preyed on," local media reported geologist and paleontologist Bernardo Gonzalez Riga as saying. Scientists discovered the remains of a foot "with all its toes and claws in an exceptional state of preservation," as well as the complete rear bones, tail, "and part of the pelvis," Gonzalez said. Such...

BUENOS AIRES -- Remains of a new species of dinosaur, christened 'bonitasaura', were discovered in southern Argentina after scientists were led to them by a 98-year-old woman, who said that she was aware of the bones since her childhood. Scientists were taken to the bones of the nine-meter (30 foot) giant, by Filomena Avila, also called Dona Tica, after convincing her that they were not fossil thieves. "Dona Tica believed we were fossil traffickers and, at first, she lied to us, saying that there are not any bones here," said Sebastian Apesteguia, leader of the paleontologists who made the discovery....

* The Tyrannosaurus might have had lips, a new study suggests * Researchers compared skulls and studied teeth for the study * Some scientists aren't convinced about this theory FILE – Stan, one of the largest and most complete Tyrannosaurus rex fossil discovered, is on display, Tuesday, Sept. 15, 2020, at Christie’s in New York. The teeth on T. rex and other big theropods were likely covered by scaly lips, concludes a study published Thursday, March 30, 2023, in the journal Science. The dinosaur’s teeth didn’t stick out when its mouth was closed, and even in a wide open bite,...

Pterosaurs with these types of beaks are better known at the time period from North Africa, so it would be reasonable to assume a likeness to the North African Alanqa. Credit: Attributed to Davide Bonadonna ======================================================================= Paleontologists have made a surprising discovery while searching through 100-year-old fossil collections from the UK – a new mystery species of pterosaur, unlike anything seen before. Lead author of the project, University of Portsmouth PhD student Roy Smith, discovered the mystery creature amongst fossil collections housed in the Sedgwick Museum of Cambridge and the Booth Museum at Brighton that were assembled when phosphate mining...

Fossil Strengthens Dinosaur-Bird Link Feb. 14 — A 130 million-year-old newly discovered fossil of a small meat-eating dinosaur found in China is further proof of the evolutionary link between dinosaurs and birds, scientists say. "This animal is not a direct ancestor to birds but it is a very close cousin. It is from a group called troodontids which is closely related to birds," Peter Makovicky of the Field Museum in Chicago said on Wednesday. The new dinosaur, called Sinovenator changii, was probably feathered and is almost the same age as the oldest known bird Archaeopteryx. "The similarities in the skeleton ...

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...

Two environmental activists glued themselves to an exhibition of a dinosaur skeleton at Berlin's Natural History Museum on Sunday to protest against the German government's climate policies. In Berlin, two women wearing orange vests stuck themselves to metal poles supporting a dinosaur skeleton that was over 60 million years old, holding a banner that read: 'What if the government doesn't have it under control?' They did not touch or do any damage to the skeleton itself.

A handout image obtained on August 23, 2022 courtesy of the Dinosaur Valley State Park shows dinosaur tracks from around 113 million years ago. A drought in Texas dried up a river flowing through Dinosaur Valley State Park, exposing tracks from giant reptiles that lived some 113 million years ago, an official said Tuesday. Photos posted on Facebook show three-toed footprints leading down a dry tree-lined riverbed in the southern US state. It is "one of the longest dinosaur trackways in the world," a caption accompanying the images says. Stephanie Salinas Garcia of the Texas Parks and Wildlife Department...

Scientists have uncovered the remains of one of the largest pterosaurs on record, researchers announced in a study published Tuesday in the scientific journal Cretaceous Research. The fossils are from the largest-ever pterosaur found in South America, and one of the largest flying vertebrates in the world, according to researchers. The discovery of two separate animals was made in an outcrop in Argentina's Mendoza province and published in April. The Thanatosdrakon amaru is a new azhdarchid, a member of the pterosaur family of large, flying predators, predominantly from the Late Cretaceous Period. The name is a combination of Thanatos, the...

The limb, complete with skin, is just one of a series of remarkable finds emerging from the Tanis fossil site in the US State of North Dakota. But it's not just their exquisite condition that's turning heads - it's what these ancient specimens purport to represent. The claim is the Tanis creatures were killed and entombed on the actual day a giant asteroid struck Earth. The day 66 million years ago when the reign of the dinosaurs ended and the rise of mammals began. The BBC has spent three years filming at Tanis for a show to be broadcast on...

Scientists find fossil from THE DAY the dinosaurs died 66m years ago: Leg of Thescelosaurus was 'ripped off in aftermath' of huge asteroid strike that wiped out most species on Earth Dinosaurs were wiped out by the Chicxulub event - a plummeting asteroid that hit Earth 66 million years ago The asteroid more than six miles in diameter slammed into what is now Mexico, leaving a 93-mile wide crater Experts found the fossilised leg of a dinosaur killed and what appears to be a fragment of the asteroid itself Findings were made at Tanis, a renowned paleontological site in North...
