Description

LAGGAN BURN Laggan Burn, lying approximately 3.5km southeast of Girvan, is a key palaeontological site in the Balclatchie (Caradoc) succession of the Girvan area. The Caradoc Epoch and Ashgill Epoch together spanned a period of time from 458 to 444 million years ago, during the Late Ordovician. The mudstones and calcareous nodules contain, in particular, a rich and well-preserved graptolite fauna of great importance in the understanding of the zoology of the extinct group. The site has also yielded conodonts and brachipods.
