Granier, Bruno, Clavel, Bernard, Charollais, Jean & MarcWeidmann, 2014, Latest Jurassic - Early Cretaceous Dasycladalean Algae (Chlorophyta) From The Morand Drilling At Montricher (Canton Of Vaud, Switzerland), Acta Palaeontologica Romaniae 10 (1 - 2), pp. 1-2 : 29

Genus Pseudoactinoporella (Conrad)

Though Granier (1995) suggested a possible synonymy with the genus Actinoporella (Gümbel) , the occurrence of a basal expansion on some laterals does not appear to be a permanent feature that would support this opinion.

Pseudoactinoporella fragilis (Conrad)

( Fig. 6 e-f)

This species is a classical species of Urgonian deposits and spans the Late Hauterivian to the Bedoulian times; to date it was never found in Lower Hauterivian strata. We identify it both in the “Urgonien jaune” and in the “Urgonien blanc”.
