Lithology and environment
Primary lithology:black lithified muddy "shale"

Includes fossils?Y
Lithology description: The Piedra Clavada Formation is composed by yellow sandstones, gray to dark mudstones, heterolithic facies and few conglomerates and coquinas.
Environment:deltaic indet.
Geology comments: In general, it is very clear that the trace fossils and invertebrates are essentially marine, which suggests, together with its sedimentary facies, a deltaic zone submerged in prodelta facies, deltaic front, interdistributary bays and interdistributary channels, and shoreface-beach facies.
