Feather in Dino Poop Hints at Birds' Survival After the Dinosaur Era

A remarkably preserved bird feather was found inside fossilized dinosaur dung from the Hell Creek Formation in Montana. Described as the best-preserved feather of its kind and the only known non-flattened dinosaur-era feather in rock, the specimen, analyzed by Jingmai O’Connor of the Field Museum and reported in Current Biology, offers new clues about how some bird lineages may have survived the mass extinction at the end of the dinosaur era.

Iridescent feathers unlock clues to a 66-million-year-old dinosaur mystery

Researchers report iridescent feathers on a 66-million-year-old carnivorous dinosaur (likely Tyrannosaurus rex or Nanotyrannus), with the shimmering plumage offering new insight into dinosaur coloration and display and helping address long-standing questions about what these predators looked like and how they behaved.

Giant Brazilian sauropod fossil reveals 120-million-year Europe–South America link

A newly identified about 20-meter-long sauropod, Dasosaurus tocantinensis, from a construction site in Maranhão, Brazil, lived around 120 million years ago. Its closest known relative was in Spain, indicating a broader Europe–South America connection and suggesting ancestors crossed Africa to South America as Gondwana broke apart. The nearly complete skeleton (tail, a 1.5-meter femur, ribs, and limb bones) provides clues to sauropod growth and biogeography. The discovery, led by researchers including Mayer and Langer, is published in the Journal of Systematic Palaeontology, and underscores how construction projects can reveal fossils and the need for preservation.

Neutron imaging reveals Scotty, the largest T. rex, died from a rib injury in a dinosaur fight

Scientists used neutron imaging at Oak Ridge National Laboratory to examine Scotty, the 43-foot, 19,500-pound Tyrannosaurus rex skeleton found in Saskatchewan in 1991, preserving tissue on the bone. 3D images showed Scotty died from a cracked rib sustained during a fight with another dinosaur, with mineralised blood vessels around the wound indicating a healing response that wasn’t enough to save him. The researchers hope these methods will unlock more prehistoric secrets.

New Triassic Sauropodomorph Unearthed at Zimbabwe’s Kariba Lake Shore

Paleontologists describe Musango matusadonaensis, a 4.5-meter early sauropodomorph from the Upper Triassic Pebbly Arkose Formation near Musango Island on Lake Kariba, Zimbabwe. This new species, part of the Unaysauridae and closely related to Musankwa sanyatiensis but distinct in anatomy and size, reinforces the idea that southern Africa hosted diverse, region-specific dinosaur ecosystems during Gondwana and suggests more fossils in the area await discovery.

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.
