Aberystwyth Grits - worm burrows

The slab near the centre of the photo is the underside of a siltstone layer in the turbidite sediments at the foot of Constitution Hill. The wiggly and elongated patterns are the filled-in imprints of worm burrows in the underlying mudstone layer, which has been eroded away. The worms would have been active in the topmost mud layer on the ocean floor when a turbidity current deposited sand on top of them, resulting in fossilised burrows after both the mud and sand layers were lithified.

Craigyfulfran GCR site

The coastal stretch north of Aberystwyth towards Clarach is known for its exposed turbidite beds Link and for their intricate folding and faulting patterns Link . The name of the site originates from a sea stack located on the foreshore (links above are to the Geological Conservation Review's site reports).

Geological Conservation Review

The Geological Conservation Review (GCR) is a database of geological reference sites in Great Britain. It is published by the Joint Nature Conservation Committee (JNCC) in the form of site reports collected in printed volumes covering different geological periods and topical areas such as fossils, minerals or geomorphology. The site reports are gradually put online in a searchable database Link .
