Some burrowers penetrated several tens of centimetres deep when producing Asterosoma, Scalichnus, Siphonichnus, Thalassinoides and Ophiomor-pha. Furthermore, composite trace fossils occur as the fill of Thalassinoides was reworked by producers of Chondrites and Taenidium-like traces.Ehrenberg, 1944. Thalassinoides is an ichnogenus of trace fossil used to refer to "dichotomously or T-branched boxworks, mazes and shafts, unlined and unornamented". [1] : 179 Facies of Thalassinoides increased suddenly in abundance at the beginning of the Mesozoic. Some Thalassinoides are large with diameters up to 10 cm. The Ophiomorpha do not branch and have relatively small diameters. Most Ophiomorpha, Cylindrichnus, Skolithos, Chondrites and Diplocraterion were observed in silty units. Muddy tidal flats can be characterized by relatively high ichnofabric indices and diversity with abundant Thalassinoides.This study examines computed tomography (CT) scans of a 15.24-cm diameter and 17.1-cm length core cut from Thalassinoides-bearing strata (Hanifa Formation, central Saudi Arabia) to explore the quantitative variability in burrow percentage when estimated using 2D views.A cropped quadrangular prism of this core allowed 202 2D slices in two vertical orientations and 165 horizontal 2D slices.5.1.4 Chert. Chert is by far the most abundant lithic fragment preserved in the Tantalus formation, making up 77% of the framework of the conglomerate and 56% of the sandstone.
