Torosaurus – A Massive-Skulled Ceratopsian, Dwarfing The Triceratops Torosaurus, pronounced TOR-uh-SAWR-us, (protuberance lizard) was an immense chasmosaurine ceratopsid (tribe Triceratopsini) dinosaur, having had one of the largest skulls of any known land animal, measuring in at a staggering nine-feet long. Chasmosaurinae is a subfamily of Ceratopsid dinosaurs—Torosaurus and Triceratops are two well-known relatives of the family […]
Ornithischia
Stygimoloch
An Herbivorous Pachycephalosaurid Stygimoloch, pronounced STIJ-eh-MOLL-uk, is generally regarded as a genus of large Pachycephalosaurid dinosaur, an herbivore (some regard Stygimoloch an omnivore). The genus received its name due the fearsome appearance of its skull. Only parts of Stygimoloch’s skull have been found to date, in Montana and Wyoming. Stygimoloch belongs to the family Pachycephalosauridae, […]
Saurischia Versus Ornithischia
The Difference Of Saurischia Versus Ornithischia Although the general public like to think that researchers categorize dinosaurs based on being carnivorous or herbivorous, this is not the case. Dinosaur species are actually most commonly categorized as being saurischian or ornithischian. So what do these terms mean and how do they differ? Let’s take a look. […]
Protoceratops
Protoceratops, pronounced pro-to-SER-uh-TOPS, (Greek—First Horned Face) was a small prehistoric ceratopsian dinosaur of the ornithischian order that existed in the Late Cretaceous Period. Named primarily as designation of a similar genus to Ceratops, meaning “before Ceratops”, it is a genus considered on many platforms to be misclassified. Its type species is P. montanus. However, now […]
Prosaurolophus
Prosaurolophus, the Duck-Billed Dinosaur Prosaurolophus (Greek—before saurolophus), pronounced pro-SAWR-O-LO-FUS, was a terrestrial genus of hadrosaurid (known as the duck-billed dinosaurs due to similarity of their head to that of modern ducks) dinosaur that lived during the late Cretaceous Period. It is most commonly characterized by its long, broad skull and a small crest present near […]
Psittacosaurus
Psittacosaurus was a Cretaceous Ceratopsid Psittacosaurus (pronounced SIT-ah-co-SAWR-us) was a primitive Ceratopsid that lived 130-100 million years ago in the Early Cretaceous period. Although it is related to the better-known Triceratops, one wouldn’t know it by appearance. Psittacosaurus was a small bipedal dinosaur that was a fraction of the size of some of its larger […]
