Debate on Dinosaur life
August 25th, 2012
riffin INTRODUCTION Some people think dinosaurs were cold-blooded; other people think dinosaurs were warm-blooded. Lots of scientists have studied the problem. There is information about posture, bone structure, and brain/body size. This essay will consider the evidence and try to come to a reasonable conclusion.

The Origin and Initial Rise of Pelagic Cephalopods in the Ordovician
August 25th, 2012
riffin During the Ordovician the global diversity increased dramatically at family, genus and species levels. Partially the diversification is explained by an increased nutrient, and phytoplankton availability in the open water. Cephalopods areamong the top predators of todays open oceans. Their Ordovician occurrences, diversity evolution and abundance patternpotentially provides information on the evolution of the pelagic food […]
Ocean Floor Sediments May Be Window on World’s Warmer Future
August 24th, 2012
riffin Analysis of seafloor sediment reveals lower oxygen levels in the ocean when the planet heated up 55.9 million years ago Digging into our planet’s past could help us prepare for a hot future. One dramatic spike in historical temperatures, the Paleocene–Eocene Thermal Maximum (PETM), occurred around 55.9 million years ago. That time was marked by […]
Ancient fossils reveal how the mollusc got its teeth
August 23rd, 2012
