Argentinosaurus (meaning "lizard from Argentina") is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina.Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, measuring 30–35 m (98–115 ft) long and weighing 65–80 t (72–88 short tons).
Rodolfo Aníbal Coria (born in Neuquén June 1, 1959), [1] is an Argentine paleontologist.. He is best known for having directed the field study and co-naming of Argentinosaurus (possibly the world's largest land animal ever) in 1993, and Giganotosaurus (one of the largest known terrestrial carnivores), in 1995 among other landmark South American dinosaurs, including Mapusaurus, Aucasaurus ...

Macronaria is a clade of sauropod dinosaurs.Macronarians are named after the large diameter of the nasal opening of their skull, known as the external naris, which exceeded the size of the orbit, the skull opening where the eye is located (hence macro- meaning large, and –naria meaning nose).
A phylogenetic analysis conducted by González Riga and colleagues in 2018 recovered Mendozasaurus as the most basal member of Lognkosauria, including Futalognkosaurus and the gigantic titanosaurs Argentinosaurus, Notocolossus, Patagotitan and Puertasaurus. [4] The following cladograms show the position of Mendozasaurus in Lognkosauria.
Its femur was roughly 1.9 metres (6.2 ft) long, somewhat smaller than the estimated 2.5 metres (8.2 ft) length of the femur of Argentinosaurus. The forelimb was shorter than the hindlimb, with a humerus 78% the length of the femur, as is typical of titanosaurs but unlike some basal titanosauriforms such as brachiosaurids. As in other ...
Citipati embryo IGM 100/971. In 1993, a small fossilized oviraptorid embryo, labelled as specimen IGM 100/971, was discovered in a nest at the Ukhaa Tolgod locality of the highly fossiliferous Djadokhta Formation, Gobi Desert, during the Mongolian Academy of Sciences-American Museum of Natural History paleontological project.
Overosaurus was described and named by Rodolfo A. Coria, Leonardo S. Filippi, Luis M. Chiappe, Rodolfo García and Andrea B. Arcucci in 2013.This species is known solely from the holotype MAU-Pv-CO-439 which consists of a fully articulated vertebral series from the 10th cervical to the 20th caudal vertebra, the ribs of the last three cervical vertebrae, six right dorsal ribs (articulated with ...
