Asteroids from the lower Aptian Lower Greensand of the Isle of Wight are described. Two articulated specimens are referred to the extant paxillosid family Pseudarchasteridae and transferred to a living genus, i.e., Paragonaster, P. wightensis (Breton, 1992). Isolated marginal plates are assigned to the widespread Cretaceous astropectinid genus Coulonia, and described as C. caseyi sp. nov. The Cretaceous genus Comptonia Gray, 1840 is referred to the Pseudarchasteridae and revised taxonomically, with the recognition of two species; C. elegans Gray, 1840 and C. bretoni sp. nov., Paragonaster wightensis is the oldest known member of the Pseudarchasteridae.

来自怀特岛(英国)上的饼干会员(下阿普提安人,Deshayesites forbesi地带)的小行星(棘皮动物),并修订了化石假体

描述了来自怀特岛的Apty Lower Greensand下游的小行星。两个铰接标本被称为现存paxillosid家庭Pseudarchasteridae并转移到居住类,即ParagonasterP. wightensis(布雷顿,1992年)。孤立的边缘板块被分配到广泛的白垩纪astropectinid属Coulonia,并被描述为C. caseyi sp。十一月 1840年的白垩纪属Comptonia Gray,被命名为Pseudarchasteridae,并在分类学上进行了修订,并承认了两种。C. elegans Gray,1840和C. bretoni sp。十一月Paragonaster wightensis 是Pseudarchasteridae的最古老的成员。
