Species
Parafavreina thoronetensis Brönnimann, Caron et Zaninetti, 1972
Taxon description
Rychliński et al., 2018a
Description: Parafavreina thoronetensis is characterized by a circular or subcircular outline in cross section, flattened slightly from the underside (“ventral” side) in some samples (Fig.3c, d). It shows two bilateral symmetrical groups of longitudinal canals (35–40 in number), of triangular or rarely crescent shape in cross section. However, this feature is poorly recognizable in the studied material. The canals are 30–50 μm in width. In longitudinal section, the canals are preserved as elongate sparite-filled voids (about 150 μm long) arranged in linear rows resembling a dotted line. One pellet shows up to six such parallel rows.
