The New York Times reports a new isotope analysis of T. rex tooth enamel that puts the dinosaur’s average body temperature at about 36°C — lower than the higher estimates previously derived from growth-rate studies, providing a fresh key data point for dinosaur physiology.
A natural-science research consortium announced on September 14 that a continuous trackway of footprints left by an adult Tyrannosaurus rex has been identified for the first time in a Late Cretaceous geological formation in North America. Individual prints approach the size of an adult human foot, marking the first concrete trace of an adult T. rex in motion. The discovery provides new physical evidence for the study of the species’ gait, social behaviour and the wider Late Cretaceous North American ecosystem, and is being described by the field as one of the most significant trace-fossil finds in decades.
Core Summary A Tyrannosaurus rex fossil named “Gus” sold for $50.1 million at Sotheby’s auction house in New York, setting a new all-time record for dinosaur fossil auctions. The 67-million-year-old skeleton attracted global attention from collectors and museums. Details Sotheby’s announced on July 14 that the well-preserved T. rex skeleton went through intense bidding before finally selling for $50.1 million. The buyer’s identity has not been disclosed, but the fossil is reportedly intended for public display. This price far exceeds any previous dinosaur fossil auction record, reflecting the continued surge in demand for rare paleontological specimens in the collector’s market. ...
[Brief] Researchers have unearthed fossil remains of a new giant dinosaur species in Thailand. The discovery provides important insights into the Cretaceous-era ecosystems of Southeast Asia. The research team is conducting detailed analysis to determine its classification and geological period.
Scientists have discovered preserved blood vessel structures in 66-million-year-old T. rex fossil bones, opening unprecedented possibilities for extracting original proteins from dinosaurs.
Scientists have identified a prehistoric giant octopus measuring approximately 62 feet in length from fossilized beak fragments, revealing a Cretaceous-era marine creature that may have been one of the ocean’s largest apex predators.
