Palaeopascichnus linearis (Fedonkin, 1976)

Taxon description

Kolesnikov et al., 2018b

Emended diagnosis: Test agglutinated, elongated, curved or rectilinear, occasionally branching, consists of a single series of globular or ellipsoidal chambers 1–15 mm in width. The series occasionally diverge dichotomously. Chambers are relatively consistent in size within a series or gradually increase in width before diverging, but the length-towidth ratio of the chambers is relatively constant along the series. The wall thickness does not exceed 1 mm. Number of chambers in a series ranges between 3 and 5 and 30–40
