Mosasaur fossils have been recovered from Late Cretaceous rocks all over the world. Most are just a fossilized tooth or perhaps a loose rib or vertebra. Occasionally, several bones are discovered still together. Conventional wisdom holds that creatures from this period died millions of year ago. If that's true, why do some still have soft tissue?

The blob lives. Or at least, it has been reconstructed in a three-dimensional computer model.

Canadian scientists have found a massive dinosaur fossil graveyard in Alberta containing so many bones that it calls into question the standard stories of slow and gradual dinosaur fossil formation. No mere river flood could account for so many casualties. So, the researchers proposed that the cause was something much more violent.

In the summer of 2002, record rainfall in the Texas Hill Country overfilled Canyon Lake. Water coursed over the top of its dam and carved huge, steep-walled canyons through the limestone bedrock downstream. The scoured riverbed, now called Canyon Lake Gorge, is over a mile long and has been cordoned off for scientific study.

A dazzling array of amber in a rainbow of colors has been discovered at Cape York in far north Australia. Plant and mammal parts, as well as insects and other arthropods, are trapped inside the gems, which formed from tree resin.
