Abstract
The new asteroid (Echinodermata) genus Brachisolaster is based on Solaster moretonis Forbes (Solasteridae), described from Jurassic rocks of Gloucestershire. Brachisolaster (Order Velatida) demonstrates that characteristic solasteroid features were defined by the Bathonian. Arms are more numerous in Brachisolaster moretonis than in living solasteroids; the appearance is suggestive of that of living Heliaster (Asteriidae). Heliaster feeds largely on molluscs and barnacles, whereas the diet of living solasteroids stresses more active echinoderms. Solasteroids use their fewer but larger arms to subdue and manipulate prey. Brachisolaster is suggested to have had feeding habits more like those of Heliaster than like those of extant solasterids. -from Author
