The '''Lower Maleri Formation''' is a [[sedimentary]] [[geological formation|rock formation]] found in [[Andhra Pradesh]] and [[Telangana]], [[India]]. It is the lowermost member of the [[Pranhita–Godavari Basin]]. It is of late [[Carnian]] to early [[Norian]] age ([[Upper Triassic]]), and is notable for its [[fossil]]s of early [[archosaur]]s.<ref name="triassicdistribution">Weishampel et al., 2004, pp.525–527</ref>

== Vertebrate fauna ==
cf. ''[[Angistorhinus]]'' and cf. ''[[Typothorax]]'' have also been recovered from it.<ref name=Indiansaupo>Novas et al, 2011</ref><ref name=TSKetal07>Kutty et al., 2007</ref>
