Diagnosis
ReferenceDiagnosis
M. Vianey-Liaud and G. Garcia 2003On the outer surfaces of the fragments, small (0.3 to 0.6 mm) nodes frequently fused in arched and irregular ridges, a few being isolated; nodes and ridges separated by deep valleys where the relatively wide (70 to 100 um) and irregular pore canals open; units of various thickness according to their position, nodes or flat areas in valleys.
Differs from Cairalloolithlls by its fan-shaped and short units, its well rounded nodes and high ridges. Differs from Megaloolithus by the frequent ridges and the wide, numerous, irregular and short pore canals.
