Drawer-Stashed Fossil Reveals Antarctica's Earliest Dinosaur

A fossil bone tucked away in the British Antarctic Survey archives for 40 years has been confirmed as Antarctica's earliest dinosaur, a Late Cretaceous sauropod tail vertebra from James Ross Island. Reanalyzed by BAS scientists, the lithostrotian titanosaur adds to Antarctica's rare dinosaur record and could shed light on Gondwana dispersal; the find, published in Acta Palaeontologica Polonica, is only the second sauropod fossil known from the continent.

Antarctica Reveals Its First Dinosaur Bone Hidden in a Forgotten Drawer

A fossil forgotten for 40 years in a Cambridge drawer has been identified as the tail vertebra of a Titanosaur, marking Antarctica’s first dinosaur bone. Originally collected in 1985 on James Ross Island during a British Antarctic Survey expedition, the specimen was re-examined by paleontologists from the Natural History Museum who confirmed the find; the dinosaur was about 23 feet long and lived around 82 million years ago when Antarctica was forested and warmer.

66-Million-Year-Old Dino Bone Reveals Surviving Collagen

A Liverpool-led study of a 66-million-year-old Edmontosaurus sacrum detected remnants of collagen and the amino acid hydroxyproline in a remarkably preserved fossil, using multiple analytical methods to rule out contamination. The findings suggest some original biomolecules can persist for tens of millions of years, offering new clues about dinosaur biology and evolution beyond bone structure.

Giant sauropod unearthed: weighs roughly the same as nine elephants

Scientists have identified a new giant sauropod dinosaur, estimated to weigh about 50–60 metric tons—roughly the weight of nine elephants—shedding light on the upper limits of dinosaur size and sauropod evolution.

France Unveils 155-Meter Sauropod Footprint Trail in Jura Rock, the Longest Yet Found

In the Dinoplagne site of the Ain region in the Jura mountains, researchers report a 155-meter-long, exceptionally well-preserved sauropod trackway dating to the early Tithonian stage of the Late Jurassic. This extends the record for the longest sauropod footprint sequence and provides detailed clues about the giant animal’s gait and size; a 2009 discovery at Dinoplagne identified a much shorter track (about 35 meters) but likewise highlighted the site’s significance. The footprints, attributed to a titanosaur, are preserved with sharp edges and intricate details, and the site remains open to visitors as scientists continue to study this geological treasure.

Dog-Sized Middle Jurassic Dinosaur Unearthed in Scotland, Hinting at Early Plant-Eater Diversity

Paleontologists unearthed Scotland’s most complete dinosaur skeleton to date—a dog-sized herbivorous ornithischian from the Middle Jurassic (~166 million years ago) on the Isle of Skye. The discovery, involving a subadult around eight years old, offers new clues about early plant-eating dinosaurs and could reshape understanding of Jurassic ecosystems, though researchers are still determining whether it represents a new species due to the fragmentary remains.

Undergrad Uncovers Hidden Late-Triassic Carnivore, Redrawing Dino History

A deformed late-Triassic skull, once dismissed, was reassembled with CT scanning by Virginia Tech undergraduate Simba Srivastava, revealing Ptychotherates bucculentus, a previously unknown carnivorous dinosaur. The discovery, published in Papers in Palaeontology, suggests early dinosaurs diversified earlier than thought and that the Herrerasauria lineage persisted longer in the American Southwest, reshaping our understanding of dinosaur evolution before T. rex.

Inside a T. rex Rib, Tiny Vessels Tell a Dinosaur's Healing Story

Using advanced imaging, researchers examined Scotty’s fractured T. rex rib and found iron-rich, mineralized blood vessel casts that trace the dinosaur’s healing and illustrate how vascular tissue can be preserved across millions of years through alternating burial conditions.

Embedded Tooth in Edmontosaurus Skull Points to Face-Off With T. rex

Scientists studying a Hell Creek Formation Edmontosaurus skull found a tooth lodged in its snout, a rare embedded-tooth fossil that lets researchers identify the attacker as Tyrannosaurus rex. CT scans show a frontal bite, the tooth’s serrations match T. rex, and bite marks suggest the predator continued feeding on the head after the kill, implying a direct encounter rather than distant scavenging.

Brazil unearths 20-meter giant dinosaur, Dasosaurus tocantinensis

Brazilian researchers describe a new giant dinosaur, Dasosaurus tocantinensis, from fossils found near Davinópolis, Maranhão. A 1.5-meter femur suggests the animal was about 20 meters long, placing it among Brazil’s largest dinosaurs, and it appears to be the closest relative of Spain’s Garumbatitan morellensis, implying a European lineage that dispersed to South America about 130 million years ago before the Atlantic opened.

Canada’s Tiny Pachycephalosaur Fossil Redefines Dinosaur Growth

A 67-million-year-old juvenile pachycephalosaur fossil from Saskatchewan, Canada (CMNFV 22039) offers the first postcranial look at these dome-headed dinosaurs, revealing long hindlimbs and rapid juvenile growth that imply faster locomotion and a different development path than previously understood.

Portugal Beach Unearths 150-Million-Year-Old Dinosaur Nest

Researchers on Portugal's Santa Cruz Beach uncovered a nest of at least ten Late Jurassic dinosaur eggs, exquisitely preserved in cliff sediment, with evidence suggesting most hatchlings may have emerged; CT scans are planned to study any embryonic material and the eggs' microstructure.

Egg-Thief Dino Used a Multi-Toothed Claw to Snatch Nests

Researchers describe Manipulonyx reshetovi, a small, bird-like dinosaur from Mongolia, with a unique forelimb featuring a giant claw, two side digits, and spikes that enabled gripping smooth eggs for night-time egg-snatching about 67 million years ago; the species was named in a December paper describing the fossil.

Ancient Argentine Dinosaur Unearths Unique Intact Skull

A newly discovered 80-million-year-old predatory dinosaur in Argentina, named Llukalkan aliocranianus, features an unusual short, horned skull with cavities that likely enhanced its hearing, suggesting it was a highly capable predator with unique evolutionary traits. The well-preserved fossil was found during a broader excavation and offers insights into the diversity of late-Cretaceous South American ecosystems.
