Characteristics ~ ~ ~ ~

Amargasaurus was a Flagellicaudatan meaning it was likely to have had a whip tail like Diplodocus or Rebbachisaurus. They had short necks relative to body size since they were grazers, most dicraeosaurs shared an environment with a diplodocid which were high grazers explaining their small size and short neck. Except for Amargasaurus which shared its environment with another dicraeosaur… The bones in its neck are debated for what they were; some thought it was a sail, and others thought it supported an extension of skin. But debate ended around the discovery of Bajadasaurus which also had the same bones but extending forward instead of backward.

History ~ ~ ~ ~

Discovered in 1991 and described by Leonardo Salgado and José Bonaparte, only one skeleton has been unearthed, but it’s remarkably complete. The remains include the neck, part of the skull, two legs, and part of the tail, offering invaluable insights into its anatomy. Amargasaurus was recovered in the same expedition that was part of the movement "Jurassic and Cretaceous Terrestrial Vertebrates of South America" in 1984 by José Bonaparte its purpose was to discover the animals of a Lost world within the Lost world. Holotype Carnotaurus MACN-CH 894 was also recovered in the movement and it is still used in research today.
