“Near Oldbury fossil shells are abundant in the upper part of the cakes 
and bottom of the Whitestone,—both the shells known formerly as Unio, 
and now called Cardinia and Anthracosia, and others, such as Producta, 
Aviculopecten...... Itis remarkable that the shells called Cardinia are 
never, or very rarely, mingled in the same mass of stone with any of 
the other shells, except in rare instances with a solitary Lingula” 
(Beete Jukes, ‘Iron Ores of Great Britain,’ pt. ii; ‘The Iron Ores of 
the South Staffordshire Coal-field, pp. 111, 112. 
Pennystone or Cakes, &c. 

I can find no record of Mollusca from any beds below the Pennystone. 
* At the Hamstead Colliery a band of marine fossils was passed through at 60 yards above the Thick Coal. Prof. 
Hull gives the Brooch Coal as 43 yards above the Thick Coal. This band was said to contain Anthracosia Urei, which 
is probably a mistaken reference.
