Abstract | dc.description.abstract | A description is provided of the first sauropod remains (i.e., isolated vertebrae and appendicular
bones) from the Late Jurassic of Aysen, in Chilean Patagonia (Toqui Formation, late Tithonian).
Although the bones found are fragmentary, they still allow the recognition of an unsuspected
sauropod diversity for this period in South America. The materials suggest the presence of at
least three different sauropod lineages: an indeterminate group of sauropods, possible
Titanosauriformes, and Diplodocoidea. A phylogenetic analysis of this last clade supports the
placement of the remains within Diplodocinae and also provides the first unequivocal record of
this clade in Late Jurassic rocks of South America. These records provide important information
about the poorly known evolutionary history of sauropods in South America before the
Cretaceous. | en_US |
