Canada's first dinosaur-era dragonfly fossil fills an evolutionary gap In a first for Canadian paleontology, a Cretaceous fossilized dragonfly wing, uncovered in Alberta's Dinosaur Provincial Park, has been identified as a new species. It's also the first known dragonfly fossil from Canada's dinosaur-aged rocks. The find, led by McGill University researchers, sheds light on a 30-million-year gap in the evolutionary history of dragonflies. /news/2025-08-canada-dinosaur-era-dragonfly-fossil.html Evolution Paleontology & Fossils Thu, 14 Aug 2025 12:06:04 EDT news674391961 Dagger beaks and strong wings: New fossils rewrite the penguin story and affirm NZ as a cradle of their evolution Remarkable new fossil discoveries in New Zealand are driving a significant reassessment of our understanding of the early evolution of penguins. /news/2025-08-dagger-beaks-strong-wings-fossils.html Evolution Paleontology & Fossils Wed, 13 Aug 2025 11:09:39 EDT news674302174 Scientists find 74-million-year-old mammal fossil in Chile Scientists have discovered the fossil of a tiny mouse-sized mammal that lived in the time of the dinosaurs in Chilean Patagonia. /news/2025-08-scientists-million-year-mammal-fossil.html Paleontology & Fossils Tue, 12 Aug 2025 03:30:17 EDT news674188206 Fresh fossil finds in Africa shed light on the era before Earth's largest mass extinction An international team of paleontologists has spent more than 15 years excavating and studying fossils from Africa to expand our understanding of the Permian, a period of Earth's history that began 299 million years ago and ended 252 million years ago with our planet's largest and most devastating mass extinction. /news/2025-08-fresh-fossil-africa-era-earth.html Paleontology & Fossils Mon, 11 Aug 2025 14:05:36 EDT news674139933 How a rare cycad's wax crystals conjure blue without pigment The endangered South African cycad Encephalartos horridus may resemble a relic from the Jurassic age, but the species itself evolved long after dinosaurs disappeared. Still, it carries a biochemical legacy inherited from its distant ancestors—plants that once thrived alongside Jurassic fauna. A team led by Hiroshima University (HU) researchers found that its spiky, silvery-blue leaves owe their color not to pigment, but to a wax-based optical effect produced by a lipid compound that may date back to the dawn of land plants. /news/2025-08-rare-cycad-wax-crystals-conjure.html Plants & Animals Molecular & Computational biology Fri, 08 Aug 2025 11:15:32 EDT news673870526 Louisiana fossils reveal mosasaur life before dinosaur-killing asteroid impact Millions of years before jazz filled New Orleans streets or fishing boats were harvesting shrimp in the Gulf, Louisiana was home to terrifying sea monsters, a tenacious mammal and a seismic cataclysm that reshaped life on Earth. /news/2025-08-louisiana-fossils-reveal-mosasaur-life.html Paleontology & Fossils Thu, 07 Aug 2025 13:10:01 EDT news673790419 Oddity from Alabama creek is tooth of dinosaur that reached 30 feet, experts say A "shiny" fossil found in an Alabama creek has been identified as the tooth of a large dinosaur that doesn't quite belong at the site, experts say. /news/2025-08-oddity-alabama-creek-tooth-dinosaur.html Paleontology & Fossils Wed, 06 Aug 2025 06:51:51 EDT news673681906 Dinosaur teeth serve as 'climate time capsules,' unlocking secrets of Earth's ancient greenhouse climate A previously unexploited source of information is now throwing new light on Earth's climate during the age of dinosaurs. Fossilized dinosaur teeth show that concentrations of carbon dioxide in the atmosphere during the Mesozoic Era, i.e., 252 to 66 million years ago, were far higher than they are today. This has been determined by researchers at the universities in Göttingen, Mainz, and Bochum following the analysis of oxygen isotopes in the dental enamel of dinosaur teeth. /news/2025-08-dinosaur-teeth-climate-capsules-secrets.html Earth Sciences Tue, 05 Aug 2025 12:45:22 EDT news673616711 An ancient predator's bone-crunching diet shift offers clues on surviving climate change About 56 million years ago, when Earth experienced a dramatic rise in global temperatures, one meat-eating mammal responded in a surprising way: It started eating more bones. /news/2025-08-ancient-predator-bone-crunching-diet.html Ecology Paleontology & Fossils Tue, 05 Aug 2025 09:12:04 EDT news673603921 Gigantic, meat-eating dinosaurs didn't all have strong bites, analysis shows A new analysis of the bite strength of 18 species of carnivorous dinosaurs shows that while the Tyrannosaurus rex skull was optimized for quick, strong bites like a crocodile, other giant, predatory dinosaurs that walked on two legs—including spinosaurs and allosaurs—had much weaker bites and instead specialized in slashing and ripping flesh. /news/2025-07-gigantic-meat-dinosaurs-didnt-strong.html Evolution Paleontology & Fossils Mon, 04 Aug 2025 11:00:07 EDT news673170301 Velociraptorine fossil with unusually strong hands suggests a new predatory niche An international group of paleontologists led by the University of Poitiers, France, report that a recently recovered velociraptorine fossil, Shri rapax, brandished unusually large, powerful clawed hands.

Despite being one of the most studied fish in history, it continues to reveal new information that could transform our understanding of vertebrate evolution. This is revealed in a study published in the journal Science Advances by researchers from the University of SĂŁo Paulo (USP) in Brazil and the Smithsonian Institution in the United States. /news/2025-07-fossil-fish-anatomy-reshaping-view.html Evolution Paleontology & Fossils Mon, 28 Jul 2025 16:01:02 EDT news672937255 Clues for dinosaurs' diets found in the chemistry of their fossil teeth You are what you eat, it turns out—even if your last meal was 150 million years ago. /news/2025-07-clues-dinosaurs-diets-chemistry-fossil.html Paleontology & Fossils Thu, 24 Jul 2025 16:20:02 EDT news672592341 Dinosaur tracks reveal first evidence of mixed-species herding behavior Footprints of a multispecies herd of dinosaurs discovered in Canada demonstrate the social interaction between different dinosaur species 76 million years ago, according to findings in a new study published in the journal PLOS One. /news/2025-07-dinosaur-tracks-reveal-evidence-species.html Ecology Paleontology & Fossils Wed, 23 Jul 2025 14:00:03 EDT news672478915 Feather-like crest on Triassic reptile challenges ideas about reptile evolution Body coverings such as hair and feathers have played a central role in evolution.

Previously, scientists had trouble establishing a consensus on the pterosaur's diet. Some suggested meat-based or fish-based diets, while others believe the pterosaur ate plants, bugs, or even that the pterosaur was a filter-feeder. /news/2025-07-evidence-pterosaur-fossilized-stomach-longstanding.html Paleontology & Fossils Tue, 15 Jul 2025 06:50:01 EDT news671726479 The biggest piece of Mars on Earth is going up for auction in New York For sale: A 54-pound (25-kilogram) rock.
