Newfound Dinosaur a Transitional Creature

Caught in the act of evolution, the odd-looking, feathered dinosaur was becoming more vegetarian, moving away from its meat-eating ancestors.

It had the built-for-speed legs of meat-eaters, but was developing the bigger belly of plant-eaters. It had already lost the serrated teeth needed for tearing flesh. Those were replaced with the smaller, duller vegetarian variety.

"I doubt seriously this animal could cut a steak with that mouth," said Utah state paleontologist James Kirkland, one of those describing the animal, based on bones found in east-central Utah ... Yahoo! News

Fossils illuminate fish evolution

Fossils of an ancient fish - dating back 450 million years, when the creatures had neither bones nor teeth - have been found in South Africa.

The finds, which are 50 million years older than any other fossil fish in Africa, will help provide a "missing link" in the evolution of early fish ... BBC NEWS

Great extinction came in phases

The greatest mass extinction recorded in Earth history did not occur as a result of one single cataclysmic event.

A joint UK-Chinese team tell Nature magazine the disaster that befell the planet 250 million years ago must have happened in phases.

Their conclusion is based on the abundance of "organic fossils" found in rocks at Meishan in southern China.

These suggest there were at least two episodes to the mass die-off that saw up to 95% of lifeforms disappear ... BBC NEWS
