LiveScience.com – Scientists have uncovered what they are calling the oldest full-body impression of a flying insect, possibly an ancient mayfly.

Scientists have identified one of the smallest dinosaur skulls ever discovered as coming from a very young Heterodontosaurus, an early dinosaur. This juvenile weighed about 200 grams. This skull suggests how and when the family of herbivorous dinosaurs that includes Heterodontosaurus made the transition from eating meat to eating plants.

A recently released study of northern and southern polar dinosaur migration indicates that some species may have migrated nearly 3,000 km in a six month period- far short of the distance needed to reach warmer climes. What’s more, the study also revealed that other species would have been forced to endure polar winters and exhibited characteristics similar to today’s nonmigratory animals when dealing with hibernating, foraging and even burrowing.

Paleontologists have long debated the function of the strange, bony crests on the heads of the duck-billed dinosaurs known as lambeosaurs. The structures contain incredibly long, convoluted nasal passages that loop up over the tops of their skulls. Scientists have now used CT-scanning to look inside these mysterious crests and reconstruct the brains and nasal cavities of four different lambeosaur species.

A catastrophic event 72.5 million years ago left a herd of giant, horned dinosaurs buried to become fossils

The mega-bird that swooped over waters covering what is now south-east England had wings that spanned five metres tip to tip and had bony teeth to grab its food

The latest research from Bottjer’s group suggests a similar slow dying during the extinction 200 million years ago at the boundary of the Triassic and Jurassic eras

New research argues in favor of a “sick earth” mechanism for most extinctions, rather than external event like an asteroid strike.
