King of the dinosaurs, late Cretaceous apex predator of western North America
A Texas fossil dating to 324 million years ago reveals an insect with 24 legs, challenging long-held views on early arthropod evolution. Researchers say this pushes back the hexapod gap and suggests insects had complex origins beyond today’s limb count.
Sotheby’s has sold a 67‑million‑year‑old Tyrannosaurus rex skeleton nicknamed “Gus” for $50.1 million, the highest price ever paid for a dinosaur at auction. The specimen, about 61–63% complete, was excavated in South Dakota from 2021–23; scientists are warning that private ownership will restrict research access.
A new study explores defending Earth from large near-Earth asteroids. It analyzes a crater-based nuclear detonation approach, noting timing is critical and early warning is essential. Researchers say this method could be the most effective for very large rocks with short warning times, though it requires complex missions.
Fossils and fossils trade are under renewed scrutiny as calls grow for legal protection of fossil finds and tighter controls on collecting, after reports of high-profile sales and ongoing debates about national-treasure status. Museums and collectors are pushing for changes while UK rules lag behind market realities.
