Coletta seca (Gow 2000, Modesto, Damiani and Sues 2002, Early Triassic, GHG 228) is a tiny reptlle nesting between owenettids and lepidosauriforms (between Owenetta and Paliguana). Two rows of vomerine teeth appear on the palate.

Distinct from Owenetta, Coletta had a larger nasal and a smaller jugal. The back of the skull was narrower.

Modesto et al. (2002) considered Coletta a procolophonid, but it is not related to Procolophon according to the large reptile tree.

Pintosaurus magnidentis (Piñeiro et al. 2004, earliest Triassic) is known from only the jawline of a skull. The rest has been restored based on sister taxa, like Contritosaurus. The teeth are quite large but fewer in number than in Coletta. The palatines each have a large tooth. Other skulls will be published soon.

Contritosaurus simus (Phaanthosaurus simus, PIN 1025/1, Cudinov and Vjushkov 1956, Ivakhnenko 1974; Early Triassic) has a small anterior naris, but a large fossa surrounding it. The pterygoid extends far below the jawline. The prefrontal invades the orbit, which is half the skull length.
