Geological Period: Silurian
Description
BLAIR FARM This small site, located approximately 5 kilometres east of the village of Dailly, is the type locality of the Llandovery (Lower Silurian) age Blair Formation. It also shows the base of the Knockgardner Formation above. The site is important because it yields the well-preserved fossil remains of microscopic fossils known as acritarchs, which were planktonic algae. Heating of the rocks has elsewhere in the region destroyed the acritarchs and low thermal maturation here, makes it possible to collect a well preserved acritarch flora. This is not normally possible in rocks of this age in Scotland. These horizons also yield common crenulata zone graptolites, fossils of extinct marine creatures. It is an important site for biostratigraphic studies of Llandovery rocks in this region.
