description
(Fig. 4 A) FIGURED SPECIMEN. — ULVG- 7319.
discussion
REMARKS The specimen figured herein presents more widely spaced costae in relation to the original description of Pessagno (1976), consisting of nine costae in lateral view. Pessagno (1976) described approximately 11 costae in lateral view, although, even in the specimens figured by him, this characteristic is highly variable. The poor preservation of the studied specimen did not allow the identification of the relict pores described by Pessagno (1976).
