The document describes sedimentary observations from a field study. Sections 1-4 describe lithological observations of muddy heterolithics that are intensely bioturbated by various ichnofauna like Phycosiphon and Teichichnus. Section 5 includes permeability maps and thin sections of microporous nodular limestones. Section 6 defines bioturbation and bioerosion. Section 7 notes observations of outer shelf facies including bioturbated mudstone, laminated mudstone, and intensely bioturbated mudstone with ichnofauna like Phycosiphon and Chondrites.
