Alvarezsaurus is a genus of small alvarezsaurid dinosaur from the Late Cretaceous period, living in Argentina, approximately 86 - 83 million years ago. Estimates suggest that it measured about 2 meters (6.5 ft) in length and weighed approximately 20 kg (45 lbs). Gregory S. Paul estimated in 2010 its weight at 3 kg and length at 1 m. It was found in the Bajo de la Carpa Formation and was named by paleontologist José Bonaparte in 1991 after the historian Don Gregorio Alvarez. The type species is A. calvoi.

Cramauchenia is an extinct genus of litoptern South American ungulate. Cramauchenia was named by Florentino Ameghino. The name has no literal translation. Instead, it is an anagram of the name of a related genus Macrauchenia. This genus was initially discovered in the Sarmiento Formation in the Chubut Province, in Argentina, and later it was found in the Chichinales Formation in the Río Negro Province and the Cerro Bandera Formation in Neuquén, also in Argentina, in sediments assigned to the SALMA Colhuehuapian. In 1981 Soria made C. insolita a junior synonym of C. normalis. A specimen of C. normalis was described in 2010 from Cabeza Blanca in the Sarmiento Formation, in sediments assigned to the Deseadan SALMA(Upper Oligocene).

Juan (Jean) Brèthes, also known as Frère Judulien Marie or Juan Brethes was an Argentine scientist, naturalist, entomologist, ornithologist, zoologist and geologist. He was the first entomologist of the National Museum, today known as the Argentine Museum of Natural Sciences. He was a close collaborator of Florentino Ameghino, and translated several of his works into French. Thanks to his intense activity, he systematized a large number of Latin American insect species. He was a precursor in the fight against agricultural pests at a time when insecticides had not been developed to combat them.
