3+ hour, 8+ min ago  (98+ words) Paleontologists in Uruguay have identified a new species of aeolosaurine titanosaur from a pair of remarkably well-preserved tailbones unearthed in the 1980s near the Uruguay River....

3+ day, 3+ hour ago  (172+ words) Today, lepidosaurs -- the reptile group that includes lizards, snakes and New Zealand’s tuatara -- are among the most diverse vertebrates on Earth, but their earliest evolutionary history remains poorly understood....

3+ day, 6+ hour ago  (141+ words) Spriggina floundersi, a marine species that lived during the Ediacaran period 550 million years ago, is one of Earth’s earliest bilaterally symmetrical animals....

4+ day, 5+ hour ago  (160+ words) Paleontologists working in northeastern Thailand have identified a new species of mamenchisaurid sauropod dinosaur, offering fresh evidence that a group of giant sauropods once thought to be almost exclusively East Asian also roamed mainland Southeast Asia....

6+ day, 2+ hour ago  (119+ words) Paleontologists in China have described a small, previously unknown Jurassic bird whose short tail offers new evidence for how the earliest birds traded their long, dinosaur-like tails for the compact tailbone that helps living birds fly....

1+ week, 10+ hour ago  (694+ words) An artist’s reconstruction of Clovis life 13,000 years ago shows the Anzick-1 infant with his mother consuming mammoth meat near a hearth. Another individual crafts tools, including dart projectile points and atlatls. A mammoth butchery area is visible nearby. Image credit:…...

The Antarctic dinosaur vertebra came from the Santa Marta Formation on James Ross Island, off the tip of the Antarctic Peninsula. Cataloged as BAS D.8621.25, the…...

1+ week, 5+ day ago  (178+ words) Urokodia aequalis, an early Cambrian marine predator from the Chengjiang biota of China, preserves the earliest known evidence of chelicerae -- the pincer-like structures that later evolved into the fangs of spiders and the pincers of scorpions....

1+ week, 6+ day ago  (486+ words) New research from the University of Bristol suggests that pterosaurs — the first vertebrates to achieve powered flight — probably displayed a much wider array of wing shapes and flying styles than fossil-based reconstructions have depicted. Pterosaurs thrived from about 210 to 65 million…...

2+ week, 5+ hour ago  (203+ words) Fossils from the Jose Creek Formation in New Mexico reveal that angiosperms (flowering plants) had built dense, fruit-bearing forests nearly 75 million years ago -- nearly 9 million years before the end-Cretaceous mass extinction that killed the dinosaurs -- challenging a long-held evolutionary narrative…...
