Bolonia lata Meunier, 1886

Taxon description

Fürsich et al., 2018

Description. The slightly positive epireliefs of this trace fossil occur on three bedding planes as a horizontal, straight, non-branched, bilobed ribbon which tapers towards one or both ends. The ribbon is composed of biserial transverse pads separated by a median furrow. The faintly to distinctly arched pads are inclined with respect to the bedding plane and are manifested on the surface as arcuate ridges. The width of the ribbon varies between 1.8 cm and 4 cm, the thickness of individual pads between 0.2 cm and 0.5 cm. The greatest observed extension of the ribbon was 8 cm.

Chamberlain, 1971

Description.-Angular meandering furrow preserved as an epirelief with narrow, rounded, lateral compression ridges on both sides. Two to 5 mm wide and 1 mm high. Slightly irregular marks across furrow, widest on crest of lateral ridges, caused by compression during peristaltic motion of animal.
