The Museo Argentino de Ciencias Naturales and its collection of
dinosaurs. The dinosaur specimens housed in the paleontological
collections of the Museo Argentino de Ciencias Naturales have
undoubtedly international significance. In addition some have
historical value, like Antarctosaurusus wichmannianus Heune, 1929, one
of the first sauropods in being collected in South America;  others
are unique in its type, as Amargasaurus cazaui Saldago & Bonaparte,
1991, a dicraeosaurid sauropod of elongated cervical neural spines,
and Carnotaurus sastrei Bonaparte, 1985, an abelisaurid theropod with
strong frontal horns. The first dinosaur bones incorporated to the
collections of the MACN were gathered by Carlos Ameghino, just before
his brother Florentino occupied the charge of Director of the Museum.
Dinosaur discoveries intensified notably with the arrival to the
Museum of Jose Bonaparte, at the end of the decade of 1970. Besides
Amargasaurus and Carnotaurus, Bonaparte collected remains of Jurassic
dinosaurs, like the sauropod Patagosaurus fariasi Bonaparte, 1986a and
the theropod Piatnizkysaurus floresi Bonaparte, 1986b, which, at their
time, formed part of the first association of Jurassic dinosaurs
recorded in South America.
