Nodosaurus


Nodosaurus

▪ dinosaur genus
      armoured dinosaurs (dinosaur) found as fossils in North America dating from 95 million to 90 million years ago during the Late Cretaceous Period. A heavy animal about 5.5 metres (18 feet) long, Nodosaurus had a long tail but a very small head and a minuscule brain. For protection against predators, it relied upon a heavy coat of thick bony plates and knobs that covered its back. The front legs were much smaller than the hind legs, and the back was strongly arched.

      Nodosaurids (family Nodosauridae) and ankylosaurids (family Ankylosauridae) are the two commonly recognized groups within Ankylosauria (dinosaur), the armoured dinosaurs. Of the two subgroups, nodosaurids are generally regarded as more primitive, having generally lived before the ankylosaurids (nearly all of which date from the Late Cretaceous). Nodosaurid ancestors of Nodosaurus are first found in Middle Jurassic (Jurassic Period) (180 million to 159 million years ago) deposits of Europe, though they are mostly known from the Early Cretaceous (144 million to 99 million years ago), and some survived to the end of the Cretaceous. Nodosaurids lacked the tail club of ankylosaurids, and their skulls were generally not as short or broad, nor was the skull covered with protective plates (scutes).
