Nanolania is an extinct genus
of rhytidosteid
temnospondyl from the early Triassic
period (Induan
stage) of south central Queensland
, Australia
. It is known from the holotype QMF 12293, a postorbital fragment associated with lower jaw fragments and from the associated paratypes QMF 14480, a laterally complete skull
with mandible
s, QMF 35247, a poorly preserved skull with right mandibular ramus, QMF 35393, a badly preserved partial skull and QMF 39666, a posterior orbital and mandibular fragment, recovered from the Arcadia Formation
in the Rewan Group. This genus was named by Adam M. Yates in 2000
, and the type species

Skull
The skull is a bony structure in the head of many animals that supports the structures of the face and forms a cavity for the brain.The skull is composed of two parts: the cranium and the mandible. A skull without a mandible is only a cranium. Animals that have skulls are called craniates...

Type species
In biological nomenclature, a type species is both a concept and a practical system which is used in the classification and nomenclature of animals and plants. The value of a "type species" lies in the fact that it makes clear what is meant by a particular genus name. A type species is the species...
