Taxon description

Hofmann, 1972

Diagnosis : Large, uniformly branching burrow systems along bedding planes, containing cylindroidal to ellipsoidal pellets. Branches generally nearly rectilinear, fairly uniformly long and wide, and developing by repeated equal, distally directed, lateral forking from opposite points along the distal half of individual segments. Burrows show multiple laminations indica

Diagnosis : Large, uniformly branching burrow systems along bedding planes, containing cylindroidal to ellipsoidal pellets. Branches generally nearly rectilinear, fairly uniformly long and wide, and developing by repeated equal, distally directed, lateral forking from opposite points along the distal half of individual segments. Burrows show multiple laminations indicative of upward displacement of burrows during successive stages of occupation.
