Episode 5:  New GiantsEdit

A Mapusaurus was first seen briefly, watching a herd of Argentinosaurus migrate.  A pack of Mapusaurus were later seen harassing the herd of sauropods. They selected their victim, a young Argentinosaurus and snacked on it without killing it.  One of the carcharodontosaurids got flattened by an adult Argentinosaurus. The pack then wandered off, waiting for the victim to die.

At the end of the episode, thousands of Mapusaurus, Skorpiovenator and Lacusovagus came to the victim - the young  Argentinosaurus that died from an injuries made by the Mapusaurus pack to feast on it.  They ate it for weeks, coming and going in a time lapse sequence until they ate everything, down to the bare bones.  When the Argentinosaurus was reduced to only bones, a Mapusaurus appeared, but wandered off.  The episode commented that when Argentinosaurus became extinct, Mapusaurus followed - a pattern followed throughout the Mesozoic world.
