I just came from Buenos Aires, Argentina!

Here are some photos of the paleontological zone of their natural history museum.

-Patagosaurus and Piatnitzkysaurus (and behind an Argentinosaurus vertebra!).

-Patagopteryx (I thought it was bigger XD)

-Amargasaurus lying eggs.

-Pterodaustro (my favorite pterosaur) model!!!!

-Model of an extinct sphenodont.

-Mosasaur model!

-CHILESAURUS!

-Austroraptor (bigger than what I imagined!).

Patagosaurus fariasi

Source: https://en.wikipedia.org/wiki/Patagosaurus

Name: Patagosaurus fariasi

Name Meaning: Patagonia Reptile

First Described: 1979

Described By: Bonaparte

Classification: Dinosauria, Saurischia, Eusaurischia, Sauropodomorpha, Plateosauria, Massopoda, Sauropodiformes, Anchisauria, Sauropoda, Gravisauria, Eusauropoda, Cetiosauridae?

Patagosaurus is a sauropod from the Callovian age of the Middle Jurassic, about 165 million years ago, known from many specimens and thus with an anatomy that is well known. It is also known from at least one juvenile, lending insight into its growth. It was found in the Cañadon Asfalto Formation in Patagonia, Argentina, lending its name. It is known from over 12 specimens and was a very unspecialized sauropod - generic long neck, long tail, small head, and quadrupedal stance. It was about 16 meters long and had similar teeth to more derived sauropods. It would have replaced all of its teeth every 58 days or so. A recent cladistic analysis found that it was more basal than Cetiosaurus, and not the sister (meaning, just as derived) genus of Cetiosaurus, so its placement in Cetiosauridae is under some debate. It lived in a lush ecosystem, with many conifers, ferns and equisetales that Patagosaurus could have fed on. It also lived near a volcano. There were other sauropods including Volkheimeria, and the theropods Piatnitzkysaurus and Condorraptor.
