liopleurodon, means "Smooth-sided tooth" is a genus of large pliosaur that roamed in seas Europe during Jurassic period. It was an apex predator during the middle and late Jurassic. Studies of
the skull have shown that it could probably scan the water with its
nostrils to ascertain the source of certain smells.
Kentrosaurus, means "Pointed lizard" is the small member of stegosaur that lived in Africa during Jurassic period.It had 9 pairs of plates on its neck, shoulders, and back, and 5 pairs of long, sharp spikes above its hips and along its tail. Kentrosaurus also had a long spike on each of its hips.
Meganeura, means "Large nerve" is the largest dragonfly that lived in Germany during carboniferous period. Meganeura
is likely to have
hunted and fed in much the same way as dragonflies do today, although
its larger size may suggest that many more creatures could have been on
the menu for it. Aside from other invertebrates potential prey may have
also included small amphibians that were rapidly evolving to
terrestrial life.
Argentavis, means "Argentina talon" is the largest fliying predatory bird that lived in Argentina during Miocene period.With
a wingspan estimated at seven meters across, Argentavis
was roughly
twice the size of the largest flying bird today (Wandering
Albatross), and only the long extinct pterosaurs
could have
rivalled and exceeded it for size.It probably hunt small mammals using it's talon and scavenged carcass.
