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.

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 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
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
