Trace Fossils from the Permo-Triassic of Arran

Abstract
Synopsis: The first identifiable trace fossils recorded in the Permo-Triassic of Arran come from an exposure within the Auchenhew Beds near King’s Cave on the west coast. The forms cf. “Siphonites”, cf. Cylindricum and epichnial burrows, preserved in micaceous sandstones and mudstones, indicate the activity of an ephemeral invertebrate, probably arthropod, fauna in a shallow fluvial-lacustrine environment of unknown salinity. These trace fossil bearing sediments occur in a regional sequence of facies indicating an upwards change in environment from fluvial through aeolian and fluvial-lacustrine to marine.
