urn:lsid:zoobank.org:act: 018D810C-5979-4B09-AE11-9E56620CF889

Spumellaria gen. and sp. indet. B – Carter 1993: 92, pl. 13, figs 6, 8, 11. — Baumgartner et al. 2008: pl. 3, fig. 11.

Spumellaria gen. and sp. indet. A – Tekin 1999: 124, pl. 23, fig. 7.

HOLOTYPE. — Sample Orbuk-15, HU.JMB.0114 (Fig. 7A).

PARATYPES. — HU.JMB.0115 (Fig. 7B), HU.JMB.0116 (Fig. 7C), HU.JMB.0117 (Fig. 7D).

TYPE LOCALITY. — Orbuklukeli section Mersin Mélange, NW of Mersin city, southern Turkey.

ETYMOLOGY. — Because of its occurrence in Rhaetian strata.

OCCURRENCE. — Upper Triassic, Rhaetian of Queen Charlotte Islands, British Columbia, Canada; El Castillo Mélange, Nicaragua / Costa Rica Border; Antalya Nappes, NE of Antalya city and Mersin Mélange, NW of Mersin city, southern Turkey.

DIMENSIONS (based on four specimens, in µm). — Maximum diameter of the cortical shell: 88-110 (holotype: 100, average: 98.5); Length of longest spine: 70-78 (holotype: 70, average: 74.3).

DESCRIPTION

Same as of the genus. Cortical shell disc-shaped, large, wider than the length of four spines.

REMARKS

Same as for the genus. This species differs from another species of Praeudalia Tekin, n. gen., illustrated as Gen. et sp. indet. in Tekin (2002b: 428, pl. 3, fig. 12) by possessing a smaller cortical shell and longer primary spines.
