- T. rex could become most expensive fossil ever - but it's a problem for scientists
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.

- T. rex could become most expensive fossil ever - but it's a problem 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.
- T. rex took 40 years to reach full size, scientists find
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.
- Bag made from ‘T. rex leather’ to be auctioned in Paris
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 finally cracked the mystery of why T. rex had such tiny arms
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.
- We may finally know why dinosaurs like T. rex evolved tiny arms
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.
- Why did T. rex have such small arms? Scientists finally SOLVE the mystery - and say the answer may lie in their giant heads
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.
- Lab-grown Tyrannosaurus leather: More chicken than dinosaur?
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.
- Blood vessels found in T. rex bones are rewriting dinosaur science
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.
- 'Gigantic' ancient octopus used jaws to crush prey and hunted alongside the dinosaurs 100M years ago: study
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 thought this was a young T. rex. They were wrong
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.
