Edwin Harris Colbert (September 28, 1905 – November 15, 2001), known as “Ned” to his friends and colleagues, was a distinguished American Paleontologist. He helped popularize the study of dinosaurs through his prolific research, writings, and 40 years of work as a curator at the American Museum of Natural History in New York. Colbert was born in Clarinda, Iowa, but moved to Maryville, Missouri during infancy. Like many young children, and most of his predecessors and contemporaries,...

Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American paleontologist, specializing primarily in vertebrates. He is highly renowned as one of the most prominent scientists of his time, having discovered and described dozens of new species. Marsh is also credited with developing what is currently the most widely accepted theory of the origin of birds. Marsh was born in Lockport, New York, to a family of moderate means. Thanks to the generosity of his uncle, George...

Styracosaurus, meaning “spiked lizard” from the Ancient Greek styrax “spike at the butt-end of a spear-shaft” and sauros “lizard” was a genus of herbivorous ceratopsian dinosaur from the Cretaceous Period, about 76.5 to 75 million years ago. It had four to six long horns, stretching from its neck frill, a smaller horn on each cheek, and a single horn jutting out from its nose, which may have been up to 2 feet long and 6 inches wide. The function/functions of these horns and frills...

Thescelosaurus, meaning “godlike”, “wondrous”, or “marvelous” and “lizard” was a genus of small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. It was a member of the last dinosaurian fauna before the Cretaceous-Paleogene extinction event around 65.5 million years ago. The completeness and preservation of many of its specimens illustrate that it might have preferred to live near streams. This bipedal ornithopod is known from...

Daspletosaurus, meaning “frightful lizard” is a genus of tyrannosaurid theropod dinosaur that resided in western North America between 77 and 74 million years ago, during the Late Cretaceous Period. Fossils of the only named species were found in Alberta, although other possible species from Alberta and Montana wait for description. Daspletosaurus is closely related to the much larger and more current Tyrannosaurus. Like most of the known tyrannosaurids, it was a multi-ton bipedal...
