End of dinosaurs
Charles Pellegrino suggests this "co-factor" in dino extinction:
During the dino era much of N. America, Europe, Asia, and Africa
were under water. And this high ratio of water to land surface
established a mild climate that dinos thrived in.
Then volcanic activity at the mid sea ridges subsided. The ridges
began to sink under their own weight, draining water from the
continents. As sea levels fell, oceanic and air currents were changed
drastically by the newly exposed land, with dramatic effects on
climates. This might have been a "major cofactor" in dinosaur
extinction.

A NEW DINOSAUR HOMEPAGE SHOWS OFF
SPECIMENS AND ART
A Royal Tyrell Museum technician, Stewart Wright, has assembled a new
dinosaur homepage. This homepage contains excellent reproductions of
Mike Skrepnick's dinosaur art, a tribute to the Tyrrell Museum's field
experience program. There is also a photo of the new ornithomimid
skull and skeleton included, along with links to many of the best
dinosaur, paleontology, and geosciences web sites.
