What were formerly considered to be lower coal measure shales 
are in the second edition of the Explanation to sheets 102 and 
112 of the Geological Survey of Maps (1875), called “ Upper 
Shales,” but as they contain a distinct and characteristic assem- 
blage of fossils corresponding with those of the basal shales of the 
coal measures of Kilkenny, Queen’s County, Tipperary, Limerick 
and Clare, the original designation is retained. Three distinct 
patches of these basal shales occur in the north of Dublin, near 
Garristown, the Naul and Westown, extending east of the “ Man- 
of-War;” a second at Featherbed-lane station, Baldongan ; and 
the third on the sea-shore at Loughshinny, between Rush and 
Skerries. The shales of these places are, in many instances, full 
of fossils, mostly marine shells such as Aviculopecten papyraceus 
Posidonomya Becheri and P. membranacea, Goniatites sphericus 
and Orthoceras Stemnhauerit. With these are occasionally asso- 
ciated fish remains and a few fragmentary stems of fossil plants. 
At some of the localities junction-beds between these coal 
measure shales and the limestone may be observed. These 
junction-beds in the list of species are marked with an asterisk
