As the world looks for more energy, the oil industry will need more refined tools for discoveries in places where searches have never before taken place, geologists say. One such tool is a new sediment curve (which shows where sediment-on-the-move is deposited), derived from sediments of the Paleozoic Era 542 to 251 million years ago, […]

Paleozoic ‘Sediment Curve’ Provides New Tool For Tracking Sea-Floor Sediment Movements
Behavioral biology of trace fossils
The potential of the ichnofossil record for exploring the evolution of behavior has never been fully realized. Some of this is due to the nature of the trace fossil record itself. Equally responsible is the separation of ichnology from the relevant areas of modern behavioral biology. The two disciplines have virtually no concepts, methods, or […]
Scientists Pinpoint Hot Spots as Earthquake Trigger Points
Scientists at Scripps Institution of Oceanography at UC San Diego have come a step closer to deciphering some of the basic mysteries and mechanisms behind earthquakes and how average-sized earthquakes may evolve into massive earthquakes. In a paper published in the Aug. 30 issue of the journal Nature, Scripps scientists Kevin Brown and Yuri Fialko describe […]
Vertibral Paleontology questioning facts on Tyrannosaur ?
Scientists have identified several of the “biggest, baddest” theropods, and everyone asks, “Which one is the very biggest?” Giganotosaurus? Spinosaurus? T. rex? Acrocanthosaurus? “I think they’re all reaching the maximum size a two-legged, large-bodied carnivore can get,” explains Peter Larson, T. rex expert (Wyrex is his eighth rex excavation!). “All of these creatures are hovering at around the same size, […]
Why Did Mammals Survive the ‘K/T Extinction’?
Picture a dinosaur. Huge, menacing creatures, they ruled the Earth for nearly 200 million years, striking fear with every ground-shaking stride. Yet these great beasts were no match for a 6-mile wide meteor that struck near modern-day Mexico 65 million years ago, incinerating everything in its path. This catastrophic impact — called the Cretaceous-Tertiary or […]
