New twist in dinosaur debate

WASHINGTON-ST. LOUIS (US)—Recent evidence suggests many dinosaurs may have been “warm-blooded” like present-day mammals and birds rather than cold-blooded like lizards. If true, their internal furnace would have enabled them to live in colder habitats, such as high mountain ranges and the polar regions, allowing them to cover the entire Mesozoic landscape. (more…)

Dinosaurs of many kinds may have burrowed to survive

On the heels of his discovery in Montana of the first trace fossil of a dinosaur burrow, Emory University paleontologist Anthony Martin has found evidence of more dinosaur burrows—this time on the other side of the world, in Victoria, Australia. Martin believes the likely burrows were made by small ornithopod dinosaurs—herbivores that were prevalent in the region and were about the size of a large, modern-day iguana.
