Episode 5: New Giants
A group of Gasparinisaura was first seen travelling over a volcanic swamp with a herd of Argentinosaurus. The giant herbivores churned up the sand and turned it to quicksand. Many Gasparinisaura fell in and sank to their deaths. They were then seen browsing with the Argentinosaurus. They then ran away when a pack of Mapusaurus appeared.
