Along the Smithy Burn, the West branch of the Podowrin Burn, 

 Mr. Tait found a brown sandy shale which because of the abundance 

 of the Bryozoan Glauconome has been called the Glauconome band. 

 This immediately overlies the fish beds and contains (215, 585) : 



Eurypterus dolichoschelus (Laurie) 

 Glauconome disticha (Goldf.) 

 Lasanius problematicus (Traq.) 

 Ateleaspis tessellata (Traq.) 

 Spirorbis sp. 

 Sponge 

 Pachytheca sp. 



The Lanarkian series is typically developed along the northern 

 limb of the anticline from the local conglomerate at the base found
