The document describes sedimentary features observed across multiple rock samples. Sample 1 contains muddy heterolithics that are intensely bioturbated with high ichnofaunal diversity, including traces of Phycosiphon, Teichichnus, Planolites, Chondrites, and Rhizocorallium. Sample 2 contains cross-bedded claystone with bidirectional foresets, thick bottomsets, and flaser bedding, along with variable bioturbation of moderate diversity including Planolites, Macaronichnus, Ophiomorpha, and Thalassinoides, indicative of a tidal channel. Sample 3 contains descriptions of bioturbation degree, ichnofauna, diversity, and tiering observed

“Those aspects of the sediment's texture and internal
structure that arise from bioturbation and bio-erosion at all
scales" (Ekdale & Bromley 1983).
“A record of the primary sedimentary conditions, original
animal community, and subsequent history of one or more
phases of biogenic activity” (Taylor & Goldring 1993).
