- Slimonia acuminata (Salt.)
- Beyrichia kloedeni (M'Coy)
- Ceratiocaris papilio (Salt.)
- Favosites asper (D'Orb.)
- Lindströmia sp.
- Glyptocrinus basalis (M'Coy)
- Crinoid stems
- Ceriopora sp.
- Strophomena (Leptaena) rhomboidalis (Wilck.)
- Ctenodonta sp.
- Cornulites sp.
- Calymene blumenbachii (Brong.)
- Encrinurus sp.
- Illaenus sp.
- Proetus stokesi (Murch.)
- Athyris (Glassia) compressa (Sow.)
- Orthis bouchardi (Dav.)
- O. (Dalmanella) elegantula (Dalm.)
- O. polygramma (Sow.)
- Orthonota sp.
- Orthoceras angulatum (Wahl.)
- O. small smooth sp.
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
