Discovery of First T. rex Recounted
On August 12, 1902, the legendary fossil collector Barnum Brown scribbled a note to his boss in New York from the wilderness of eastern Montana, "Quarry No. 1 contains (several bones) of a large Carnivorous Dinosaur... I have never seen anything like it..." With that announcement, Brown resurrected Tyrannosaurus rex from the 65 million-year-old rocks of the Missouri Breaks.

You can experience all the excitement and troubles that accompanied this momentous discovery in Brown's own words in a new book by Lowell Dingus entitled Hell Creek, Montana, which also recounts many other important events in evolutionary and American history that occurred in these rugged badlands, including the perilous passage of Lewis and Clark.

Nests Are First Ever Discovered for Giant, Plant-eating Dinosaurs
A team of researchers announced today in the journal Palaios the discovery of the first-known, well-preserved nesting structures made by giant, sauropod dinosaurs. Discovered in the remote desert of Patagonia, these 80 million-year-old nests are each between 4 and 5 feet in diameter and contain from 15-34 eggs. Geologic evidence indicates that the dinosaurs intentionally excavated the nests before laying their eggs.

New, Meat-eating Dinosaur Discovered
A team of researchers announced today in the Journal of Vertebrate Paleontology the discovery of a fearsome, carnivorous dinosaur previously unknown to science. This imposing predator, named Aucasaurus garridoi, roamed the floodplains of Patagonia 80 million years ago, preying on giant, long-necked, plant-eating dinosaurs called titanosaurs. Read the accounts to the right to find out more about this fascinating new dinosaur, including how it was discovered.
