Ardgowan. 



No systematic collection appears to have been made from the locality 

 near Ardgowan (fig. 1). It possibly corresponds with a locality mentioned 

 by McKay in Geological Keports, 1881, p. 122, " Index of Fossiliferous 

 Localities," No. 175. 



Stratigraphically, there is no defijiite rock-succession exposed in the 

 immediate neighbourhood of the shell-beds. At the Devil's Bridge, one 

 mile distant, it is evident that the dip of the beds there would carry 

 them not far below the Ardgowan exposure. The equivalents of the 

 Hutchinson's Quarry beds and the calcareous tuffs also outcrop about one 

 mile to the east in a manner that supports this conclusion. Lithologically 

 the shells and shell-fragments are embedded in a loose grey sand with some 

 glauconite ; in fact, the beds are almost exactly similar to the Target 

 Gully beds, and they appear to belong to the same horizon.
