Type Species

Lithodendron mitratum Quenstedt, 1857, p. 709, pl. 86, fig. 9; Subsequent Designation Vaughan and Wells 1943, p. 231

Type Specimen: Syntype; GPIT AN/1157-1158; Verified; Dry Preserved

Type Locality: Kimmeridgian (Upper Jurassic) from Nattheim (Germany)

The unique syntype is a silicified specimen. It was figured again in another view in Quenstedt 1880, pl. 171, fig. 42



Dendroid corallum with deep calices and rapid increase in diameter of branches. Corallite outline various in shape due to the Taschenknospung. Radial elements compact free septa s.s., unequal, of a fairly constant thickness, straight or curved. Distal edge smooth, steeply inclined near the wall, inner edge smooth, lateral faces smooth. No palis. Microstructure. No hexameral symmetry but a bilateral symmetry marked by a cardinal septum. Endotheca of large vesicles. No columella, no synapticulae. Cutting peripheral wall, externally smooth, probably a pachytheca.


Wells, 1956 considered Mitrodendron as a senior synonym of Aulastrea but Mitrodendron is generally considered as more clearly phaceloid and has a marginarium that is not complete around the septal apparatus (Eliášová, 1975). Amphiaulastrea is cerioid.
