A 215-million-year-old crocodylomorph fossil unearthed in Gloucestershire has been identified as a new genus and species, Galahadosuchus jonesi, revealing a slender, upright, cursorial predator built for land speed rather than swimming and expanding our view of Late Triassic crocodile diversity ahead of the Triassic–Jurassic extinction.
Researchers describe Yunnanocyclus fortis, a near-complete Early Triassic crustacean from the Guiyang biota in Guizhou, China, notable for preserved appendages and unusually robust mandibles that are highly mineralized. Three specimens reveal a broader distribution for cyclidans, extending into eastern Tethys, and support an early diversification after the Permian–Triassic extinction.
On a Somerset beach in 2020, 11-year-old Ruby Reynolds and her father found jawbone fragments that led scientists to identify Ichthyotitan severnensis, a giant ichthyosaur potentially about 82 feet long. Further fossils confirmed a whale-sized marine reptile from the Triassic, offering insights into ancient oceans and showing how a shoreline discovery can rewrite natural history.
A 215-million-year-old crocodylomorph fossil discovered in southwestern England in 1969 has been reexamined and identified as a new species, Galahadosuchus jonesi, revealing a land-dwelling predator of the Late Triassic and underscoring the long-hidden value of museum collections.
A PNAS study using CT-based 3D models and vibration simulations suggests Thrinaxodon could hear faint sounds across 38–1,243 Hz (optimal ~1,000 Hz at 28 dB), indicating tympanic hearing with jaw-attached ear bones and pointing to an earlier stage in mammal-like hearing after the end-Permian extinction.
A new study reexamines over 50 fossils from the Late Triassic period in Britain, revealing they are ancient coelacanths, related to modern species, and correcting past mislabeling. These findings shed light on the diversity and ecology of coelacanths just before the end-Triassic extinction, emphasizing the importance of museum collections in scientific discovery.
Argentinian scientists discovered a nearly complete skeleton of Huayracursor jaguensis, one of the world's oldest dinosaurs from the late Triassic period, providing valuable insights into early dinosaur evolution. The small herbivore, about two meters long and 18 kilograms, was found at high altitude in the Andes and dates back approximately 230-225 million years.
Paleontologists discovered a new species of long-necked dinosaur, Huayracursor jaguensis, from the Late Triassic period in Argentina, providing insights into early dinosaur evolution and diversity.
A new species of early theropod dinosaur, Anteavis crurilongus, was discovered in Argentina, dating back to the Late Triassic period, providing insights into early dinosaur diversification and ecological changes during that era.
The study reports a Carnian theropod with unexpectedly derived features, shedding light on early dinosaur evolution during the first radiation, supported by comprehensive phylogenetic and paleoenvironmental analyses.
A 240-million-year-old fossil of a tiny reptile named Agriodontosaurus helsbypetrae, predating dinosaurs, was discovered in the UK, providing new insights into the evolution of lepidosaurs, a group that includes lizards, snakes, and the tuatara, and challenging previous assumptions about their early features.
Scientists discovered the oldest known lizard ancestor in southwest England, dating back 242 million years, which challenges previous assumptions about reptile evolution and shares features with the modern tuatara.
The discovery of the 242-million-year-old lepidosaur fossil Agriodontosaurus helsbypetrae in the UK challenges previous beliefs about early reptile evolution, revealing unexpected traits and suggesting a more complex evolutionary history for lizards, snakes, and the tuatara.
Paleontologists reanalyzed a Triassic fossil jaw from Wales using 3D digital reconstruction, confirming it as a new species of large predatory theropod dinosaur named Newtonsaurus cambrensis, dating to about 202 million years ago, and highlighting Wales's significance in paleontological research.
The article describes the discovery of Agriodontosaurus helsbypetrae, the oldest known lepidosaur, which provides new insights into the early evolution of lepidosaur feeding adaptations, skull morphology, and the timing of key evolutionary events in the Triassic period, including the origin of Rhynchocephalia and Lepidosauria.
