Silurian
GEOGRAPHY AND CLIMATE: North America and Eurasia join to form Caledonian Mountains, Continents flooded by shallow seas, limestone deposited.
TERRESTRIAL ANIMAL LIFE: Scorpions, Millipedes and possibly Eurypterid's come out of the water.
PLANT LIFE: Primitive psilopsid plants live at edges of water.
SEA LIFE: Marine invertebrates, Crinoids, Brachiopods, Trilobites, Nautiloids and Graptoites. Reefs built by tabulate Corals, Eurypterid's in brackish waters, Fish become abundant in seas and fresh waters. |

Geological Guide to Pentland Hills
Deerhope Formation
The Pentland Hills is famous for Silurian shales, siltstones and mudstones. These are rich in fossils. There are four main formations covering the Wenlock and Llandovery stages.
Deerhope Formation (Deerhope burn and Gutterford burn)
Laminated fossiliferous siltstones, mudstones and shales, no sediment coarser than siltstone, bioturbation common in fine-grained sediment. Fossils include rugose corals, brachiopods, bivalves, trilobites and pelmatozoans.
Cock Rig Formation (North Esk River in old quarries)
Medium- and coarse-grained, locally flaggy, cross-stratified sandstones, interbedded with clast-supported and poorly graded conglomerates.
Wether Law Linn Formation (Wether Law Linn burn)
Silty mudstone, mudstone, siltstone and fine-grained sandstones.
Henshaw Formation (North Esk River and Henshaw burn)
Red medium- and coarse-grained sandstones and conglomerates with finer grained sediments.
