In Depth
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.
