This species is characterized by its triangular shape, the flattening of the ventral borders and the reticulated surface. monostorii Forel and Grdinaru (2018). Schematic palaeoenvironmental model for the late Carnian Mufara Formation basin (see also Fig. 2018 Acratia maugerii n.sp. 14. Dimensions. 4, only fig. Based on the new material this determination was revised and they are attributed to Hungarella forelae. It is pointed out here that the sediments of the Mufara Basin at Monte Gambanera do not show vortex structures which were recognized in the Mufara Basin at Monte Scapello. TuvalianCarnian, Tropites subbullatus/Anatropites spinosus zones, Monte. Lateral view of a left valve, PCM O FS59. Dimensions. The tropites would be found . The original stratification and the sedimentary structures have been completely destroyed because of continuous agricultural processing of the pelitic soils and their very consistency which determines frequent drifts and landslides. However, for the time being we have not enough specimens to settle this question. ; Sohn: 23-24, pl.

The valve surface is reticulated with 4 small pustules distributed parallel to AB; in dorsal view, the flanks are parallel. L=886910m; H=600643m. Francesco Sciuto.
