Although
Demandasaurus is not represented by a lot of
complete fossil material,
it has been identified as a rebbachisaurid sauropod.
As a
rebbachisaurid, Demandasaurus was a form of
diplodocid sauropod,
and an offshoot of the Dicraeosaurinae. Demandasaurus
would have
course been related to the type genus of the Rebbachisauridae,
Rebbachisaurus,
but it has also been popularly considered to be
related to the North African genus Nigersaurus.
The
genus name Demandasaurus is a reference to the
Sierra de la Demanda,
a mountain sub-range of the Iberian Peninsula. The species name D.
darwini is in honour of Charles Darwin, the progenitor of
modern
evolutionary theory.
