This change in microfacies distribution may reflect a change in the basin morphology between Lower and Upper Carnian related to evolution from a distally steepened shelf or ramp to a more accentuated morphology, such as an abrupt shelf-break or slope (Fig. C: holotype, right lateral view of a complete carapace, PMC O25 H 13/10/2019; D: paratype, right lateral view of a complete carapace, PMC O 81 P 13/10/2019.

According to many authors, the Mufara basin is located in a transitional position between the bathyal Neotethys facies to the south and southeast and the carbonate platforms that surround it (Figs. The Mufara Basin was a site of rapid and intense sedimentation probably linked to rapid bottom currents which, sometimes, displaced and transported (also in vivo) microfaunas from more superficial neighbouring environments. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. 1; Crasquin et al.
