The Blue Ridge geologic province is a distinctive highland region that also exposes Virginia’s oldest rocks. In central and northern Virginia, the Blue Ridge Mountains rise dramatically to elevations above 1,200 m (4000’) with local relief up to 1000 m. In southern Virginia, the Blue Ridge forms a broad plateau-like upland that rises over 500 […]ABSTRACT – A sandstone bed with abundant Skolithos linearis burrows is described from the Late Eocene of Aguilar, Aínsa-Jaca Basin, (South-Central Pyrenees).Skolithos cf. serratus is the dominant trace fossil, being closely spaced (~ 160 burrows/m2), slightly inclined, and having sharp, irregular boundaries with delicate scratch ornament.

Skolithos in the Lower Cambrian Antietam Formation of South Mountain, Pennsylvania

Skolithos pipe rock clasts in the Chester Formation ‘Pipe rock’ is an ichnofacies that typifies Cambrian–Ordovician shallow-marine successions. It is characterised by closely spaced, thin vertical tubular burrows (usually Skolithos Haldeman), typically penetrating quartz arenite or quartzite matrices.

From 4503 ft to the top of the core at 4470ft., the sediments are thin interbeds of burrowed to bioturbated muddy sandstone (Facies 3) and sandy mudstone (Facies 2) containing Skolithos and Terebellina . This entire interval is interpreted as mainly lower shoreface deposits, although thin transgressive shales are interpreted to be present.An important distinction here is that although elements of the Skolithos Ichnofacies are abundant in tidal settings, many of the vertically oriented ichnofossils represent an engagement in deposit feeding rather than filter feeding (Gingras et al. 1999; Dashtgard et al. 2008). This is, again, an ethological strategy made possible by the large ...We apply a method of estimating finite strain that can be widely used in Armorican quartzites affected by transpressive regimes. The method proposed uses data from Skolithos, which are quite common in these rocks.The main assumption is that the orientation of the finite strain ellipsoid can be represented by the cleavage and the stretching lineation observed in the rocks.2. Marine ichnofacies. Eight marine archetypal assemblages (Fig. 7.1) have so far been formally defined (Genise et al. 2000)—the Psilonichnus, Skolithos, Cruziana, Zoophycos, and Nereites that are usually arranged bathymetrically along the marine profile from coast to deep sea and Teredolites, Glossifungites and Trypanites ichnofacies (the …The Blue Ridge geologic province is a distinctive highland region that also exposes Virginia’s oldest rocks.

The characteristics of the studied ichnoassociation are explained by the significant turbidity of the Ligurian shelf, which favours domichnial, suspension-feeding strategies that are typical of the Skolithos Ichnofacies. As such, the sabellid tubes from the Ligurian Sea are palaeontologically important to identify similar current-swept, high ...The brown-colored, vertical to subvertical structures shown above are Skolithos trace fossils.
