Type Species
Campesteria prolixia Caruthers and Stanley, 2008: 486, fig. 5.14, 5.17, 5.18, 5.21, 5.22, 6.1-3; Monotypy Caruthers and Stanley, 2008: 486
Type Specimen: Holotype; UMPC 22089 (MI 8302); Verified; Dry Preserved
Type Locality: Lake Cowichan, Vancouver Island, Canada. Parson Bay Formation, Rhaetian, Late Triassic
Classification
Diagnosis
Colonial, meandroid to pseudomeandroid; no ridges, wall or epitheca; corallite large; intercorallite spacing wide. Calices interconnected through abundant septa linkages.Septa ornamented with trabecular tips along distal margin.
Description
Well described, discussed and illustrated in Caruthers and Stanley, 2008.
Comparisons
Superficially resembles genus Margarastraea Volz (1896), e.g. M. klipsteini (Frech in Volz 1896:55,pl.5,fig.7) and M. deningeri Wilckens (1937:179,pl.7,fig.1), with low-lying meandroid corallites. Differs from these corals in having septa made of thick trabeculae, showing teeth-like trabecular tips on the distal septal margin. Within genus Margarastraea Frech, septa have a midseptal zone of small trabeculae, never forming thick distal ornamentation.
Remarks
The species, under the name of Margarastraea pulchra Montanaro-Gallitelli, Russo and Ferrari, 1975, was described by Stanley 1994 from Norian Pucará group, central Peru.
