A supervolcano blasting Yellowstone National Park to smithereens may capture the imagination, but the region’s real risk comes from earthquakes, researchers reported here Sunday (Oct. 27) at the Geological Society of America’s annual meeting.

Morning recess at St. Augustine Catholic School in Culver City, Calif., is like recess in many other schools. Children run and play in the afternoon sun. But nearby, away from the basketball hoops and the games of tag, the staff is preparing.

The hypothetical family that a group of Highland men allegedly was trying to protect when they destroyed a rock structure was more likely to die on the drive to Goblin Valley State Park than to be crushed by a falling rock.

For paleontologists Randall Irmis and Andrew Milner, the tiny stuff matters, especially when you’re exploring the dawn of big reptiles. Microscopic fossilized pollen, two-inch fishes, even the color of the rock that bones are embedded in say a lot about the landscapes dinosaurs roamed, the climate, what they ate and what their prey ate.

A dinosaur skeleton discovered by an eagle-eyed high-school student turns out to be the smallest, youngest and most complete duck-billed dinosaur of its kind ever found. This Cretaceous-era herbivore, Parasaurolophus, walked the Earth some 75 million years ago. The dinosaurs in this genus are best known for their impressive tube-shaped head crests, which may have been used for display or perhaps to amplify the animals’ calls. The little specimen, dubbed “Joe,” was so young that its crest was a mere bump on its head.

All it takes is a flash. Lightning strikes the ground, creating temperatures of more than 3,000 degrees. The sand around the lightning strike fuses together, and fulgurite is formed. What are fulgurites? The word – based on the Latin world for thunderbolt – refers to a hollow glass tube formed when lightning strikes soil, silica, sand or even rock. These amazing structures – sometimes referred to as “petrified lightning” or “lightning stones” – don’t look like the transparent glass in your windows or kitchen cabinets. Instead they are complex structures that resemble a cross between a vegetable root and some of the more crystalline minerals such as mica. They vary in shape and size – most are only a few inches long – and they tend to form around the path of the dispersing electric charge of the lightning.

The paleo-tectonic maps of retired geologist Ronald Blakey are mesmerizing and impossible to forget once you’ve seen them. Catalogued on his website Colorado Plateau Geosystems, these maps show the world adrift, its landscapes breaking apart and reconnecting again in entirely new forms, where continents are as temporary as the island chains that regularly smash together to create them, on a timescale where even oceans that exist for tens of millions of years can disappear leaving only the subtlest of geological traces.

Until recently, Bob Smith had never witnessed two simultaneous earthquake swarms in his 53 years of monitoring seismic activity in and around the Yellowstone Caldera.

Now, Smith, a University of Utah geophysics professor, has seen three swarms at once.

Paleontologists in St. George are sifting through thousands of fossils, all recovered from the construction site of the Southern Parkway. And some may point to the discovery of a new dinosaur species.
