Description
Clypeolus tortugaides (Cramer, 1966a) Miller, Playford, and Le Hérissé, 1997
Fig. 5O.
Material.— One specimen recorded. Sample 4-62521 V42/2). Subcircular vesicle, divided in fields by the concavo-convex wall. Ludfordian of Argentina. Quebrada Ancha locality, Los Espejos Formation.
Remarks. —It is considered as a fresh water palynomorph, from transitional marine-freshwater environment (Le Hérissé et al. 2013). The specimen from the Los Espejos Formation constitutes the first record of South America.
Stratigraphic and geographic range. — It was only recognized in the Upper Ordovician of Chad (Le Hérissé et al. 2013) and Canada (Delabroye et al. 2011), in the middle Llandovery of Saudi Arabia and in the Silurian of Spain Miller et al. 1997 and references therein).
