Vectipelta (meaning "

osteoderms. It was historically known as the "Spearpoint ankylosaur" prior to its description.[1][2]

Discovery and naming

Life restoration

The Vectipelta

osteoderms.[1] At first the remains were assigned to Polacanthus.[4]

The fossil material was initially described in a PhD thesis by Thomas J. Raven and concluded to represent a new taxon in 2021.[5] 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.[6]

In June 2023, Pond et al. 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.[1]

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.[1]

Classification

Pond et al. (2023) recovered Vectipelta as the

phylogenetic analyses are shown in the cladogram below, with Wealden Group ankylosaurs highlighted:[1]

Ankylosauria

Ecology

The Wessex Formation spans a considerable period of time of probably several million years, and therefore not all animals known from the formation are likely to have been contemporaneous. Vectipelta is likely millions of years older than Polacanthus.[1]
