- An Ichthyosaur’s terrible, horrible, no good, very bad day 160 million years ago
A rare fossil discovery reveals a tooth embedded in an ichthyosaur’s vertebra, likely from a giant pliosaurid attack 160 million years ago. The find provides evidence of a predator-prey interaction between marine reptiles during the Mesozoic era.
- Chinese fossil find shows birds shed their dinosaur tails step by step
A fossil found in China indicates that birds evolved short, feathered tails from their dinosaur ancestors through a gradual process rather than a sudden change. This transition was crucial for birds' survival after the mass extinction 66 million years ago.
- 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.

- First dinosaur bone from Antarctica found in a drawer
The first dinosaur bone found in Antarctica was discovered in a drawer. The fossil, collected in 1985, is part of the tail of a Titanosaur.
- 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.
