For the past twenty years, Eoraptor has represented the beginning of the Age of Dinosaurs. This controversial little creature–found in the roughly 231-million-year-old rock of Argentina–has often been cited as the earliest known dinosaur.05-Dec-2012

Everything we know about non-avian dinosaurs is based on fossils, which include bones, teeth, footprints, tracks, eggs, and skin impressions. For centuries, people throughout the world have discovered amazing fossilized bones and footprints. Early finds inspired legends and fairy tales, as people imagined that these bones belonged to giants or huge monsters.

Some consider Barnum Brown, who began his career at the American Museum of Natural History in 1897, to be one of the greatest dinosaur hunters of the late 19th and early 20th centuries. He began his career at the American Museum of Natural History in 1897. Many of his greatest discoveries, including the first specimens of Tyrannosaurus rex ever found, are on display in the Museum’s dinosaur halls.

Today, in addition to patience and sharp observation skills, paleontologists employ new technologies to solve unanswered questions about dinosaurs and other fossils. Advanced imaging technology, such as CT scans, allow paleontologists to see the three-dimensional structure of fossils, often without having to remove the matrix.

Paleontologists incorporate the research of biomechanics, applying the principles of both physics and engineering to reconstruct the biological movement of non-avian dinosaurs. The information gleaned from fossil bones along with observations of both the movement and the musculature of living animal species help scientists model how non-avian dinosaurs may have moved.
