Tarbellastraea

Alloiteau, 1950, p.145

Type Species

Astrea ellisiana Defrance, 1825, p. 382; Original Designation Alloiteau, 1950, p.145

Type Specimen: Neotype; MNHN I.P.-R10933; Lost; Dry Preserved

Type Locality: St-Paul-lès-Dax, Cabanes, France (Miocene, Early Burdigalian)

Alloiteau (1950) established the genus "Tarbellastraea" without a morphologic diagnosis, and designated "Astrea ellisiana Defrance" as the type species of the genus. He subsequently provided a diagnosis in Alloiteau (1952, 1957). The holotype was reported by lost in Alloiteau (1957), who established the neotype given above and figured it on plate 8, figure 4, 15. This neotype was reported as lost by S. Barta-Calmus (pers. comm. 1994).

Classification

Diagnosis

Plocoid colonies; extracalicular budding; cylindrical corallites, < 3.5 mm in diameter; septo- to parathecal; 3-4 septal cycles, with the first cyle being prominent; weak or absent paliform lobes; sublamellar to lamellar columella; thin costae; tabulo-vesicular coenosteum.

Comparisons

Tarbellastraea is morphologically most similar to Antiguastrea; both genera are plocoid with extracalicular budding, and have thin costae, a tabulo-vesicular coenosteum, and a lamellar columella. Tarbellastraea differs from Antiguastrea by having more coenosteum, smaller corallites, fewer septal cycles, and prominent primary septa. Tarbellastraea is also similar to the Montastraea annularis complex in colony form, but differs by having a lamellar columella, thin costae, and partially vesicular coenosteum. It is assigned to the Family Merulinidae based on its similarity to the Montastraea annularis complex.

Remarks

The micromorphology and microstructure of Tarbellastraea have not been studied in detail. For additional description, see Budd, Bosellini, and Stemann (1996)

Distribution

  • Southern Europe; Oligocene - Miocene
