Thalassinoides.

Paleophycus and Thalassinoides belong to the Cruziana ichnofacies, while the Skolithos burrow probably belongs to the distal Skolithos ichnofacies. The thin mud laminae draping the ripple-bedded sandstones represent fines winnowed out of the sands during wave reworking and deposited subsequently from suspension.The Upper Leaf of the Hambleton Oolite is seen excellently in the low cliff on the southern side of the Brigg. Numerous limestone-infilled Thalassinoides burrows descend from the base of the Upper Leaf into the soft sandstone of the Birdsall Calcareous Grit. The tough, impure limestone contains well-preserved bivalves and ammonites.Ophiomorpha in Late Turonian sandstones in Bohemian Cretaceous Basin, near Hřensko in Czech Republic.
