Rinconsaurus
was a relatively small titanosaur
that lived in South America during
the late Cretaceous period. Not too much is known about Rinconsaurus
other than it appears to have had a more gracile (lightweight)
build than some titanosaurs. Teeth associated with the type specimen
are also termed chisel-like which means that Rinconsaurus
probably
snipped off fronds of vegetation rather than stripping it between
peg-like teeth like some sauropods. Rinconsaurus
is thought to be
closely related to Aeolosaurus
which has sometimes seen it described as
a member of the Aeolosaurini.
Another
titanosaur from the same formation as Rinconsaurus
is Antarctosaurus.
