Alamosaurus
Alamosaurus (; meaning "Ojo Alamo lizard") is a genus of titanosaurian sauropod dinosaurs, containing a single known species, Alamosaurus sanjuanensis, from the late Cretaceous Period of what is now southern North America. Isolated vertebrae and limb bones indicate that it reached sizes comparable to "Argentinosaurus" and "Puertasaurus", which would make it the largest dinosaur known from North America. Its fossils have been recovered from a variety of rock formations spanning the Maastrichtian age of the late Cretaceous period. Specimens of a juvenile "Alamosaurus sanjuanensis" have been recovered from only a few meters below the Cretaceous-Paleogene boundary in Texas, making it among the last surviving non-avian dinosaur species.
Dinosaurs: Giants of Patagonia
"Strong One" is first shown among an "Argentinosaurus" nest with hatchlings venturing out. The narrator announces that if "Strong One" survives, he will grow to become one of the largest creatures the Earth has ever known. Then, depicting just how precarious life was, a "Unenlagia" arrives and steals an egg, which it runs off with to feast on elsewhere. At this point, we travel back to the present day in order to witness Rodolfo Coria's discovery of "Argentinosaurus". The narrator explains that Coria owns his own museum, the Museo Carmen Funes (the museum is featured in the movie as we see Rodolfo Coria in his museum with one of his daughters, as he shows her casts of "Argentinosaurus" and "Giganotosaurus" skeletons). We see Coria as he arrives at a digging site with his daughters, where he and his team work on digging out an enormous backbone, which one scientist declares larger than any other bone he had seen. They discover that the bone belonged to a large sauropod. They named it "Argentinosaurus", meaning "Argentinian Lizard".
