Scientists solved the mystery of the mass Allosaurus grave

The Cleveland-Lloyd dinosaur bone bed has been a puzzle for paleontologists for many years. It’s home to the densest collection of Jurassic era dinosaur fossils, which includes numerous Allosaurus fossils. Since the bone bed’s discovery in the 1920s, numerous hypotheses have been proposed to explain its origin—including theories of a mass poisoning event, drought, or even dinosaurs […]

Surprising discovery places Triceratops-like dinosaurs in eastern North America

For the first time ever, researchers have evidence of horned dinosaurs roaming eastern North America near the end of the Age of Dinosaurs. Researchers discovered a tooth fossil dating 68 million years back, with unmistakable features pointing to its owner, a Triceratops-like dinosaur. Until recently, it was thought that ceratopsids—horned dinosaurs—were only found in western North America. […]

The first complete ankylosaur fossil gets its name from Ghostbusters

Ankylosaurs were among the last non-avian dinosaurs; they walked on four legs and had wide armoured bodies and large horns. But much of what we know of ankylosaurs has been reconstructed from incomplete skeleton fragments. In a recently published paper, ROM researchers describe the most complete ankylosaur skeleton ever found in North America. The 75-million-year-old […]

“Baby Louie” fossilized dinosaur embryo finally finds its family

The identity of a dinosaur found in a huge egg clutch in China in the 1990s is described in a new paper. The embryo became known in the paleontology community as “Baby Louie”; it’s now identified as a new species of bird-like oviraptorosaur. The species has been named Beibeilong sinensis, which translates as “Chinese baby […]

Newly discovered feathered dinosaur sheds light on the evolution of flight

A newly discovered troodontid species is the earliest example of a bird-like dinosaur with asymmetric feathers—a physical trait associated with the evolution of flight. The new species, named Jianianhualong tengi, was described from a nearly complete skeleton with preserved feathers. The fossil dates from the Early Cretaceous period— approximately 100-145 million years ago—and was found in north-eastern […]

Fossil leads to recognition of birdlike reptiles that preceded early dinosaurs

Certain physical traits previously thought to be unique to dinosaurs evolved much earlier, a new study suggests. Fossil analysis of a newly described species, named Teleocrater rhadinus, places this carnivorous animal in a new spot on the evolutionary tree, directly after the split between birds and crocodilians. Teleocrater marks the first of an entirely new clade […]

Evidence of earliest life on Earth found in northeastern Canada

The earliest living organisms on Earth are thought to have lived in hydrothermal vents underwater. Researchers analyzed jasper rocks from the Nuvvuagittuq belt in Quebec that may have originated from such submarine vents, and found evidence of structures similar to other bacterial life in Earth’s early oceans. Authors say there are additional signs of biological activity […]

First evidence of a Middle Triassic dinosaur that gave birth to live offspring instead of laying eggs

A new discovery offers proof that an ancient relative to birds and crocodiles gave birth to live young. New research from an international team of paleontologists describes a fossil of a pregnant Dinocephalosaurus – a long-necked, aquatic reptile from the Middle Triassic. The 245- million-year-old archosauromorph carried an embryo inside its rib cage, facing forward. […]

Oldest protein found in a 195-million-year-old dinosaur bone

A new discovery beat the record for the oldest preserved protein by over 100 million years. Researchers used a new technique to examine a 195 million-year-old bone of a Lufengosaurus dinosaur without risking contamination. Their analysis showed traces of preserved collagen in parts of the bone where blood would pass through. Typically, soft tissue in […]

Distant relative of the iguana found in Montana

The geographical origin of Pleurodonta, one of the two subdivisions of the Iguania suborder, has been unclear for many years. The oldest representative of the prehistoric iguanas was thought to come from Brazil; but a recent analysis removed it from the iguana’s evolutionary tree altogether. Two skeletons of giant herbivorous lizards found in Montana, US, […]
