A team of scientists from the Berkeley Geochronology Center and UC Berkeley have determined the most precise dates yet for the dinosaur extinction 66 million years ago and for the well-known impact that occurred around the same time, and concluded that they were simultaneous. While the impact probably was not the sole reason for the dino die-off, it was likely the last straw.

Scientists find oldest dinosaur, or closest relative yet
December 5, 2012:
UC Berkeley graduate student Sarah Werning and University of Washington post-doc Sterling Nesbitt analyzed a museum fossil collected 80 years ago and concluded that the dog-sized creature may have been the earliest dinosaur yet found, having walked Earth 10 million years before previously known dinosaurs.
Cycads are not “living fossils” from Dinosaur Age
October 21, 2011:
Plants called cycads flourished during the dinosaur era, but unlike the dinosaurs, they survived into the present and have been collected and treasured as “living fossils.” A new study by UC Berkeley biologists demolishes that idea. Living cycads are not “fossils” – they evolved only within the past 12 million years.
Dinos r-o-a-a-r-r-r at Lawrence Hall
June 6, 2011:
Bigger and scarier than ever, T. rex and his dinosaur friends at the Lawrence Hall of Science have gotten new sensor-activated roars, among other features, as part of a major renovation. The “Dinosaurs Unearthed” exhibit is open through 2011.
T. rex more hyena than lion
February 22, 2011:
Was T. rex really the king of the forest? A new census of dinosaurs in Montana’s Hell Creek Formation shows that T. rex was far too abundant to be a top predator. It probably subsisted on a broad variety of dead as well as live animals, much like today’s hyena.
