Vectisaurus (/"VEK-ti-SORE-us"/; "Isle of Wight lizard") was a name given to fragmentary dinosaur remains discovered on the Isle of Wight, England, dating to the Early Cretaceous period (approximately 125 million years ago). Initially described by Hulke in 1879, the genus and single species Vectisaurus valdensis are now considered nomina dubia (doubtful names) within paleontology.

Historical Classification

The original identification of Vectisaurus was based on limited fossils, including vertebrae, ribs, and pelvic bones. Early analysis suggested it might be a smaller sauropod, a group of large, long-necked, quadrupedal herbivores. However, subsequent discoveries and analysis have cast doubt on this classification.

Current Status

Modern research indicates that the features initially attributed to Vectisaurus cannot reliably distinguish it as a unique dinosaur genus. It's likely that the discovered material belongs to other, more established sauropod genera. As a result, the name Vectisaurus is rarely used in contemporary paleontological literature.


Despite the uncertain status of Vectisaurus, the fossils were discovered in the Wessex Formation, representing a warm, floodplain environment rich in vegetation. True sauropods were present in this region during the Early Cretaceous.

Significance and Ongoing Research

While Vectisaurus is no longer considered a valid dinosaur name, its story highlights how paleontological understanding can evolve as additional fossils are found and analytical techniques advance. The Isle of Wight remains an important location for dinosaur discoveries, potentially yielding new information about the sauropods that lived in Europe during the Early Cretaceous.
