Ichnofossil Nomenclature

 


This figure gives nomenclature typically used for describing ichnofossils. The central rectangle depicts a hypothetical fossil containing zone enclosed or bounded by sharply defined upper and lower surfaces or bedding planes. These surfaces are probably the easiest physical features of sedimentary rocks to identify in an outcrop. They are used to subdivide successions of sedimentary rock into their beds and are traditionally used to determine the relative order and timing of the accumulation of the sediments forming the beds.
