The newly-discovered dinosaur lived in what is now Argentina during the Late Cretaceous epoch, approximately 95 million years ago. Scientifically named Astigmasaura genuflexa, the species was about 18 m …

Paleontologists say they have discovered the 76-million-year-old footprints of a ceratopsian dinosaur-dominated herd in Dinosaur Provincial Park in Alberta, Canada. The discovery provides the first evidence of mixed-species herding behavior in dinosaurs, similar to how modern wildebeest and zebra travel together on the African plains. A herd of ceratopsians (Styracosaurus albertensis) accompanied by an ankylosaur (Euplocephalus tutus) walk through an …

The Gobi Desert just gained another actor in its cast of Late Cretaceous characters. Paleontologists have unveiled Shri rapax, a stocky, two legged predator with a body that stretched only about 6.5 feet (2 meters) but had some serious weaponry. Unearthed after a winding journey through private collections, and eventually repatriated to Mongolia, the fossil shows a creature that roamed …

In a groundbreaking discovery, researchers have uncovered 9,000-year-old rock art that offers new insights into the relationship between ancient humans and dinosaurs. These petroglyphs, etched into rocks in Serrote do Letreiro, an agricultural site in Paraíba, Brazil, are positioned near dinosaur footprints believed to date back to the Cretaceous Period, approximately 66 million years ago. A Significant Discovery The petroglyphs, …

Scientists have discovered a dinosaur that might have chirped like a bird, a finding that suggests the evolutionary origins of birdsong may be far more ancient than we previously thought. In a paper published last week in the journal PeerJ, an international team of researchers describes a 163-million-year-old fossil found in northeastern China’s Hebei Province. The fossil dinosaur, which they’ve …

The wrists of birds are incredibly complex and functionally crucial in both flight and the folding of wings at rest, says Will Newton.  To stabilise their wings during flight, birds rely on a tiny bone known as the pisiform. This bone was long thought to have been lost in the early ancestors of birds, only returning as they started to …

In a groundbreaking discovery at Dinosaur Ridge, Colorado, scientists have unearthed evidence of a unique form of courtship behavior among theropod dinosaurs, relatives of the famous Tyrannosaurus rex. This new find, as reported by Live Science, suggests that these prehistoric creatures used a kind of “moonwalk” to impress potential mates around 100 million years ago. The discovery, published in Cretaceous …

Around 100 million years ago, male dinosaurs entered a “mating arena” in Colorado and danced their hearts out to attract females, a new study suggests. Researchers uncovered a series of mating display scrapes preserved on the surface of rocks at Dinosaur Ridge in Jefferson County, Colorado. The state is known for dinosaur track sites, with previous studies suggesting that dinosaurs …

A fascinating discovery in the world of paleontology has shattered the Hollywood-inspired image of dinosaurs popularized by films like Jurassic Park. A newly identified dinosaur species, Pulaosaurus qinglong, discovered in China, presents a significant shift in how scientists think about dinosaur behavior. Instead of the traditional portrayal of terrifying, roaring creatures, Pulaosaurus is believed to have communicated with chirps, much …

An extraordinary set of dinosaur footprints discovered at Dinosaur Provincial Park in Alberta, Canada has revealed the first evidence of mixed-species herding behaviour in the area. The fossilised footprints were uncovered in July 2024 at the UNESCO World Heritage Site, a rugged landscape made famous by its fossil-rich deposits. Yet, despite the incredible abundance of skeletal remains, dinosaur footprints and …
