Delsatia is an early mammaliaform genus that lived during the Late Triassic and has been found in the Gres infralisiques Formation of France. The type species, D. rhupotopi, was named in 1997.Sigogneau-Russell D. & Godefroit P., 1997 - A primitive docodont (Mammalia) from the upper triassic of France and the possible therian affinities of the order, sér. II a, t. 324, p. 135-140 It was originally tentatively placed within the Docodonta, but subsequent studies disagree with this; Delsatia is seen by most as a basal mammaliaform.Z.
