Genus COROLLITHION Stradner, 1961
Corollithion acutum Thierstein, 1972
(Pl. 2, Figs. 4-6)

Ellipsochiastus quadriserratus Worsley, 1971, p. 1308, pl. 1, figs. 36-38 (invalid).
Corollithion acutum Thierstein, 1972, p. 438, pl. 2, figs. 1-9.
Corollithion acutum (Thierstein) Covington and Wise, 1987, pl. 20, fig. 4.

Remarks. This small elliptical species of Corollithion is described by Thierstein (1972) as having "40 to 50 nonimbricate elements surmounted by a narrow rim." However, he illustrated a paratype (pl. 2, fig. 3) that has approximately 30 elements and in which the angle between the crossbars approaches 90 degrees. Smaller specimens of this species were observed in this study and are constructed of 20 to 30 elements (Pl. 2, Figs. 5, 6), whereas the larger, rarer forms possess 40 to 50 elements (Pl. 2, Fig. 4). This smaller form is believed to be the same as Worsley's (1971) Ellipsochiastus quadriserratus and is considered here synonymous with Corollithion acutum. The angle between the crossbars in the larger forms is clearly less than 90 degrees. In the smaller forms this angle approaches 90 degrees.

Occurrences. Rare to few in sediments of Valanginian through Aptian age from ODP Holes 638B, 638C, and 641C. Worsley (1971) used the first occurrence of this species as a datum for the Berriasian/Valanginian boundary; however, we could not use it because of its rare and sporadic occurrence downhole.

TAXONOMIC NOTES

Foraminifers

Frondicularia rhaetica Kristan-Tollmann, 1964
(Pl. 2, Fig.1)

Frondicularia rhaetica n. sp. Kristan-Tollmann, 1964, pl. 32, figs. 1­8.
Frondicularia rhaetica Kristan-Tollmann, in Tollmann and Kristan-Tollmann (1970), pl. 8, fig. 15.
Frondicularia otamitaensis n. sp. Strong, 1984, pl. 2, figs. 40, 41.
Frondicularia rhaetica Kristan-Tollmann in Strong, 1984, pl. 2, figs. 42­46; pl. 8, figs. 172, 174.

Remarks. Frondicularia rhaetica is present in all the marl units of Rhaetian age in the Eastern Alps and is known throughout the Tethys to the southeastern border region of New Zealand, where its occurrence is already in the Norian.

Ophiacantha subtilirugosa Kristan-Tollmann, n. sp.
(Pl.3, Figs. 1, 6)

Derivation of name. From the Latin subtilis (subtle) and rugosus (Plicated), after the finely plicated outer surface of the laterals.
Description. The eight laterals are moderately arched with faint or missing construction . There are three to four medium-sized, not very projected bases of thorns and one or two flat pillars at the proximal edge.
Remarks. The striated laterals differ from Ophiura longivertebralis Wolburg, 1939, described from the Liassic of Lower Saxony. Besides this, the bases of the thorns are smaller and more numerous.
Type strata. Upper Triassic, Rhaetian marls.
Size. Holotype: length, 0.4 mm; width, 0.35 mm.
Holotype. Lateral view (Pl. 3, Fig. 4).
Type locality. Northern slope of the Wombat Plateau (16°30'S, 115°14.4'E, water depth 4800­4260 m).
