New species of uniquely horned dinosaur identified

The Triceratops family tree just got a little spikier. A decade ago, a retired nuclear physicist uncovered the large skull, legs, hips and backbone of a dinosaur on his land near Winifred, Mont. Now, the remains have been identified in a new study as a new member of the ceratopsid family, dubbed Spiclypeus shipporum, meaning “spiked shield.”

Scaling up: Mega-dino babies were mini adults

Even the largest dinosaurs to walk the planet had to start out small, hatching out of eggs, but whether these were miniature versions of adults has been a long-standing question. Now a new study looking at fossils belonging to a specimen of Rapetosaurus krausei, a type of titanosaur, that died at just a few weeks of age is revealing just how fully formed some of these eventual giants were at an early age.

Ancient dinosaur migrations analyzed

Many studies have sought to track the movements of dinosaurs as they migrated across the supercontinent Pangea before and during its breakup. Now, researchers using a method called “network theory” have shed new light on dinosaur migration patterns.

Seeds may have saved bird-like dinosaurs from extinction

About 66 million years ago, nearly three-quarters of life on Earth, including all species of nonavian dinosaurs, were wiped out. However, a few species survived the mass extinction event, including the Neornithes, the ancestors of modern birds. A new study suggests they may have done so by relying on seeds when other food sources were scarce.

Statistics shine light on T. rex family tree

Tyrannosaurus rex is one of the most recognizable dinosaurs, but the tyrannosauroid family tree is also occupied by many lesser-known cousins — such as Xiongguanlong and Lythronax — along with some large holes. Now, researchers have produced a new phylogenetic family tree including all of the known tyrannosauroid species that highlights the largest remaining gaps and provides clues as to how they might be filled.

Fossil dinosaur illuminates evolution of tyrannosauroid body sizes

Tyrannosauroid dinosaurs were the dominant predators of the terrestrial ecosystems in which they roamed for much of the Late Cretaceous, from about 80 million to 66 million years ago. Some, like Tyrannosaurus rex, reached lengths up to about 13 meters and heights of nearly 4 meters. Their large size and keen senses — relatively large nasal passageways suggest a heightened sense of smell — are considered to have been keys to their success.

Benchmarks: May 12, 1905: Andrew Carnegie donates 'Dippy the Dino'

As one of the world’s wealthiest philanthropists, Andrew Carnegie had come to expect that people would praise and honor him, but May 12, 1905, would be an unusual day for the Pittsburgh steel magnate. Never before had he been honored for donating a dinosaur. Carnegie’s contribution of a massive plaster model of a Diplodocus — at the time the largest-known animal to have ever trod the planet — to London’s Natural History Museum was part of the Scotsman’s dream to rid the world of war, which he called “the foulest blot upon our civilization.”

Travels in Geology: Discovering Denver's dinosaurs

A rich paleontological legacy makes Denver, Colo., one of the best places in the world to learn about dinosaurs, with numerous fossils and trackways at sites nearby.

Getting there and getting around Denver

Denver International Airport is the best arrival point for exploring Denver and the surrounding area. A car is necessary to see many of the attractions described here. If you fly in, you can rent a vehicle at the airport or take the new light rail into town and rent a car as needed. Although all of these sites are open year-round, snow sometimes obscures the tracks during winter and early spring, and trails can be muddy. May through October is an ideal time to visit the region.
