Secuicollacta Nazarov & Ormiston, 1984 sensu MacDonald (1998)
Secuicollacta Nazarov & Ormiston, 1984: 75 . — MacDonald 1998: 587.
Palaeosphaera Renz, 1990: 372 (n. syn.)
Parasecuicollacta Won, Blodgett & Nestor, 2002: 953 .
TYPE SPECIES. — Secuicollacta cassa Nazarov & Ormiston, 1984 ( Nazarov & Ormiston 1984: 75, pl. 4, fig. 5).
AGE AND LOCATION OF TYPE MATERIAL. — Silurian, Southern Urals, Russia.
TAXON CODE. — 075.
STATUS. — Valid.
DIAGNOSIS. — “ Haplentactiniidae c эктопическим расположением внутреннего каркаса, который представлен 5-6 и более лучами. Развитие апофизов на лучах и их соединение образуют 1-2 изометричные грубосетчатые оболочки” ( Nazarov & Ormiston 1984: 75).
DIAGNOSIS (English translation). — “Haplentactinidae with an ectopic location of inner spicule which contains 5-6 or more rays. Development of apophyses on rays and their connection form 1-2 coarse-meshed isometric shells”.
REMARKS
MacDonald (1998) emends the broad diagnosis ofNazarov & Ormiston (1984) to exclude two-shelled forms such as species he placed in Diparvapila , restricting Secuicollacta to single shelled species, whose shell is formed “mainly of primary units; spicule ectopically placed, three to six rays with one ray perpendicular to other rays; spicule rays continue directly as spines” ( MacDonald 1998: 587).
