sentences:  The vegetation of the Wessex Formation was savannah- or chaparral-like, and included Caytoniales, cycads, ginkgos, conifers, and angiosperms.Other pterosaurs from the Wessex Formation include "Caulkicephalus", ""Ornithocheirus nobilis"" (which is considered a dubious species), an undetermined ctenochasmatine, an azhdarchoid, and one or two other undetermined istiodactylids.This diversity is comparable to that seen in other parts of the world during the Early Cretaceous, and the lack of toothless pterosaurs may be due to preservation bias.
