| Abstract: | The first partial skeleton of a stegosaurian dinosaur was discovered in a brick pit in Swindon, UK in 1874. Since then, numerous
stegosaurian remains have been discovered from Europe, North America, Africa and Asia, and continue to be discovered regularly.
Stegosaurs are known from the Middle Jurassic to the Early Cretaceous; no definitive evidence of the clade is known from younger
deposits. New discoveries are improving our understanding of stegosaur biology and showing that stegosaurs were more morphologically
diverse than was previously realized. A new phylogeny, which includes all valid stegosaurian taxa, largely agrees with previous
studies and shows the European Dacentrurinae was sister taxon to Stegosaurus. Poor resolution at the base of Stegosauria is probably due to the fragmentary nature of many of the Chinese taxa. |
