Type Locality: Lower Aptian of Romania.

The holotype of the type species is housed at UJ (Krakow) under 124 P 190.

Classification

Diagnosis

Solitary (?colonial), flabellate. Lateral and upper surfaces strongly ribbed. Costosepta thick, compact, with strong outgrowths laterally. Columella absent. Wall septoparathecal. Endothecal dissepiments vesicular.

Remarks

Morycowa (1971, p. 130) described the genus Trochoidomeandra as a colonial coral with radially arranged collines. As later pointed out by Turnšek (in Turnšek and Mihajlovic, 1981, p. 26) the collines entirely correspond to septa in solitary corals. In addition, she recognized the close relation of Trochoidomeandra with the rhipidogyrid genera Psammogyra and Rhipidogyra, especially in reference to the occurrence of thick septa, well-developed lateral ornamentation of septa, and microstructure. Based on the different type of septal ornamentation (long and distinctly laterally outgrowing), she created the new family Trochoidomeandridae.
