Early Cambrian phosphatic microfossils from southern Spitsbergen (Hornsund Region)

A new phosphatic-microfossil species, Hadimopanella apicata sp. n., from the Bonnia-Olenellus Zo ne (upper Lower Cambrian) of southern Spitsbergc n is described. The microfossils are discoidal in shape, with a cone-li ke elevation at the upp er side. They consist of a fibrous core, with its fine structure discernible afte r etching, and a hyaline cover. The microfossils resemble dermal sclerites of primitive vertebrates. Their strat igraphic significance is briefly discussed.
