Mandasuchus is an extinct genus of loricatan pseudosuchian from the Manda Formation of Tanzania, which dates back to the Anisian stage of the Middle Triassic.

[4][5] Charig and two coauthors suggested in a 1965 study dealing with saurischians that Mandasuchus was a possible ancestor of the "prosauropods" (basal sauropodomorphs), without explanation.

He proposed that it was in the same genus as the European archosaur Ticinosuchus ferox due to the similarity of some homologous postcranial bones, but withheld final taxonomic determination of Mandasuchus until Charig provided a published description of the material.

Mandasuchus was finally formally described in 2018 by Richard J. Butler and colleagues, as part of a multinational investigation into the fossils of Triassic rift systems in Tanzania and Zambia.

The lower edge and sides of the cervicals are concave while the rib facets (dia- and parapophyses) and articular processes (pre- and post-zygapophyses) are stout.

A small muscle scar is present on the rear edge near the glenoid (shoulder socket), similar to one observed in Batrachotomus, albeit less distinct.

[2] The femur has many archosaurian hallmarks near the hip, such as enlarged proximal tuberosities, a mound-like fourth trochanter, and possibly a groove on the upper surface of the femoral head.

The tibia is straight and possesses typical pseudosuchian features, while the incomplete fibula has a knob-shaped iliofibularis scar in its upper half.

The ankle has many suchian features, including a flexed (albeit indistinct) tibial facet on the astragalus, and a wide, expanded calcaneal tuber offset from the calcaneum's contact with the fourth distal tarsal.
