Melnikova, 1996:10

Type Species

Thamnomargarosmilia prima Melnikova, 1996: 12, pl. 2, fig.1; Monotypy Melnikova, 1996: 10

Type Specimen: Holotype; PIN 4598/51; Verified; Dry Preserved

Type Locality: Left side of the Djilghakochusu valley, at mouth, SE Pamirs, Shaimak suite, Upper Carnian-Lower Norian

Well described and illustated in Melnikova 1996 (see above) and 2001:56,pl.17,fig.1

Classification

Diagnosis

Phaceloid - thmnasterioid. Increase by marginal intracalicular budding with lamellar, temporary linkages between centers of adult and daughter corallites. Radial elements septocostal and biseptal. Endotheca dissepimental. Epitheca pellicular. Microstructure margarophylliid, with midseptal zone zigzag, and with lateral subvertical rows of thick granules.

Description

Well described and illustated in Melnikova 1996 (see above) and 2001:56,pl.17,fig.1

Comparisons

From phaceloid Margarosmilia which increased by intracalicular budding producing equivalent corallites without skeletal linkages between centers, Thamnomargarosmilia differs by peripheral inception of centers with lamellar linkages with the center of the adult corallite and formation of temporary thamnasterioid relations within phaceloid corallum.

Remarks

Two species are known.
