Article: A new alga from the Carboniferous Frosterley Marble of northern England
A new alga from the Frosterley Marble (Namurian; Carboniferous) of northern England is reconstructed from fragmentary material. It is compared with the Carboniferous genera Kulikia and Sphinctoporella, sharing with them the distinctive profusion of spherical cavities within the calcined axial surround or 'sleeve'. It differs from them in being formed of successional separate calcified discs or verticil units, which came apart after death, and is thus described as Frosterleyella diaspora gen. et sp. nov.
