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.
A significant fossil discovery of a Tenontosaurus in West Texas has expanded the known range of this herbivorous dinosaur during the Early Cretaceous, providing new insights into dinosaur distribution, ecosystems, and environmental adaptation in North America.
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.
Scientists reexamined 1916 fossils from New Mexico and identified a new species of giant duck-billed dinosaur, Ahshislesaurus wimani, which lived about 75 million years ago and could reach 40 feet in length, revealing greater diversity among hadrosaurids during the late Cretaceous period.
A 20-year-old fossil of a brachiosaur foot found in Wyoming has been confirmed as the largest ever discovered, measuring nearly one meter across, and has provided new insights into the dinosaur's range across North America, thanks to modern 3D scanning techniques.
Paleontologists in China have discovered a new long-necked dinosaur species, Mamenchisaurus sanjiangensis, from the Late Jurassic period, challenging previous ideas of East Asian dinosaur isolation and highlighting the diversity and adaptation of sauropods in ancient ecosystems.
Scientists have discovered preserved melanosomes in Diplodocus fossils, revealing that the dinosaur likely had a speckled, possibly iridescent appearance, challenging previous depictions of its dull coloration.
Researchers in China have identified a new long-necked dinosaur species, Mamenchisaurus sanjiangensis, from the Late Jurassic period, shedding light on the diversity and evolution of sauropods in East Asia and challenging previous notions of geographic isolation during that era.
A 190-million-year-old dinosaur fossil, identified as a new species called Glacialisaurus hammeri, was discovered under Antarctic ice. The fossil, a sauropodomorph, provides insights into early dinosaur evolution and suggests a diverse Jurassic ecosystem in Antarctica, with multiple species coexisting in a cold, seasonal environment.
A rare near-complete skull of a Pachycephalosaurus, a dome-headed herbivore from the Cretaceous Period, was found in South Dakota and will be displayed at the Smithsonian's National Museum of Natural History for a limited time. The fossil is significant due to its rarity and the insights it provides into dinosaurs living just before their extinction, and it was donated by philanthropists Eric and Wendy Schmidt.
A remarkably well-preserved fossil of the Jurassic herbivorous dinosaur Pulaosaurus qinglong was discovered with a rare ossified voice box, seeds, and stones in its stomach, providing new insights into its diet, feeding behavior, and potential vocal abilities, suggesting some dinosaurs may have produced complex sounds.
Researchers from the University of Chicago discovered remarkably detailed dinosaur mummies of Edmontosaurus, preserved through a process called clay templating that captured soft tissues, skin, and even hooves, providing unprecedented insights into the dinosaur's appearance and anatomy.
Scientists discovered Tongnanlong zhimingi, a massive sauropod dinosaur from the Late Jurassic period in China, estimated to be up to 92 feet long, enriching our understanding of dinosaur diversity and biogeography during that era.
A new small, fast-running dinosaur species named Enigmacursor mollyborthwickae was discovered in Colorado, helping clarify the diversity of small herbivores in the Jurassic Morrison Formation and highlighting the importance of digitization and detailed taxonomy in paleontology.
Scientists in China have discovered the first hatchling fossil of Liaoningosaurus paradoxus, a small ankylosaur, challenging previous beliefs about its size and development. The fossil provides new insights into the early life stages of armored dinosaurs, their growth patterns, and raises questions about their habitat and evolution.
