Vectipelta
Vectipelta is an extinct genus of ankylosaurian dinosaur recovered from the Early Cretaceous Wessex Formation of England. The genus contains a single species, V. barretti, known from a partial skeleton including several osteoderms. It was historically known as the "Spearpoint ankylosaur" prior to its description.
Discovery and naming
The Vectipelta holotype specimens, IWCMS 1996.153 and IWCMS 2021.75, were discovered in November 1993 and March 1994 in sediments of the Wessex Formation near Chilton Chine on the Isle of Wight, England. The holotype consists of a partial skeleton including many cervical, dorsal, sacral, and caudal vertebrae, partial pectoral and pelvic girdles, elements of the fore- and hindlimbs, and several osteoderms. At first the remains were assigned to Polacanthus.The fossil material was initially described in a PhD thesis by Thomas J. Raven and concluded to represent a new taxon in 2021. A May 2023 study proposing a paraphyletic Nodosauridae included the "Spearpoint ankylosaur" in its phylogenetic dataset, although it was given the placeholder name "Polywotsit" in the supplementary information.
In June 2023, Stuart Pond and colleagues described Vectipelta barretti as a new genus and species of ankylosaurian based on these fossil remains. The generic name, "Vectipelta", is derived from "Vectis", the Roman name for the Isle of Wight. The specific name, "barretti", honours palaeontologist Paul Barrett of the Natural [History Museum, London|Natural History Museum].
Vectipelta is the first ankylosaur identified from the Isle of Wight in 142 years, suggesting that the myriad of specimens previously assigned to Polacanthus and Hylaeosaurus may actually represent multiple taxa.
