A Tyrannosaurus rex fossil named 'Gus' sold for $50.1 million to an anonymous bidder, setting a new record for dinosaur fossils. The previous record was nearly $45 million for a stegosaurus in 2024, and 'Gus' replaces a T. rex named 'Stan' as the most expensive dinosaur fossil sold. Scientists advocate for 'Gus' to be publicly displayed in a museum.

A 67-million-year-old T. rex skeleton named Gus sold for $50.1 million at a Sotheby's auction in New York, setting a new fossil sale record. The skeleton, found in South Dakota, is 61% complete by bone count and includes rare features like a complete pelvis and both feet. The previous record was held by a Stegosaurus fossil sold for $44.6 million in 2024.

A Tyrannosaurus rex fossil named 'Gus' is set to be auctioned at Sotheby's in New York City. The skeleton could sell for up to $30 million, with this not being the first time dinosaur bones have been sold at auction.

A 67 million-year-old Tyrannosaurus rex fossil is set to be auctioned in New York with a pre-sale estimate of $30 million, potentially making it the most expensive fossil ever sold. Scientists are concerned about the implications of such a high-value sale.

A 67 million-year-old Tyrannosaurus rex fossil will be auctioned in New York with a pre-sale value of $30 million. The sale could make it the most expensive fossil ever, but poses challenges for scientists.

A 67 million-year-old Tyrannosaurus rex will be sold in New York with a pre-sale value of $30 million. Scientists face challenges due to the fossil's potential high price.

A new study of 17 tyrannosaur fossils found that Tyrannosaurus rex likely took about 40 years to reach its full size of eight tons, extending previous estimates by 15 years. Scientists previously believed T. rex reached full size faster than now indicated by the research.

A leather bag made from Tyrannosaurus rex cells will be auctioned in Paris by Giquello, with an estimated price exceeding US$500,000. The bag was created using collagen traces from a T. rex femur found in Montana 25 years ago and biotechnologies to produce 'genuine T. rex skin'.

Scientists may have solved the mystery of why Tyrannosaurus rex had small arms, suggesting evolutionary trade-offs rather than functional necessity. The article references evolutionary principles, noting that evolution doesn't prioritize simultaneous optimization of all traits.

Five different groups of predatory dinosaurs independently evolved disproportionately small arms, likely due to their large and powerful heads. The article highlights that this trait was observed across multiple dinosaur lineages.

Scientists have solved the mystery of why Tyrannosaurus rex had small arms, and the answer may be related to their giant heads. The small arm size is likely due to the large head size. This discovery provides new insights into the biology of T. rex.

A handbag marketed as the world's first T. rex leather product is facing scrutiny from the scientific community regarding its authenticity. Scientists are questioning whether the lab-grown leather actually comes from dinosaur DNA or if it's essentially modified chicken leather.

Scientists discovered preserved blood vessels in a fractured rib of a Tyrannosaurus rex fossil named Scotty, using synchrotron X-rays to study the healing process. This finding is reshaping understanding of dinosaur biology.

A study by Hokkaido University researchers revealed that ancient octopuses lived 100 million years ago, coexisting with dinosaurs and reaching lengths up to 20 meters. Fossilized jaws found in Japan and Vancouver Island suggest these predators used powerful jaws to crush prey, challenging previous assumptions about marine food chains dominated by vertebrates.

Scientists have reclassified Nanotyrannus as a distinct dinosaur species, not a juvenile T. rex, based on growth patterns in a tiny throat bone from the original fossil. This smaller predator, about half the size of a T. rex, likely coexisted with its larger cousin, adding complexity to prehistoric ecosystems.
