POPSFossils tell of mass exodus from sea Creatures could develop some protection from the sun in the water, but the land was wide open, and predators were yet to get anywhere the efficiency of ocean based predators. They can understand why shelled arthropods had the protection to survive, but can't understand the survival of soft bodied things like worms and Molluscs? then perhaps they can explain why a slug like creature evolved a shell and branched unto the Snail genotype. i don't imagine life is safe anywhere for exposed slugs and worms, and solar radiation, particularly UV Light can accelerate development. and change. Perhaps they were moving to the place that was the least dangerous.

POPSCow-like dinosaur sucked up plants They found the 'backup teeth, by CT (Computed Tomography) Scan of the skull. The dinosaur's posture was determined, by studying the canals of it's brain's balancing organs. They also say that the vertebrae were paper thin, and while it was difficult to imagine them coping with stresses of every day use, they have the 'grinning face' of the specimen to prove it was possible.

POPSDid Mega-volcanoes kill the Dinosaurs ? They have concluded that the massive volcanic eruptions, happened about 280,000 years after the asteroid strike. I'm wondering how the meteor strike would have worked on the Tectonic scale. Sure seems like the kind of thing that could shake up some inactive volcanoes. In geological time, 280,000 years is not a particularly long time.
