Answer to Question 1

Ichthyosaurs were porpoise-like marine reptiles with a streamlined body, powerful tail for propulsion,
and flipper-like forelimbs for maneuvering. They probably couldn't come on land, and so gave birth to
live young.



Answer to Question 2

Flowerless seed plants that could colonize all parts of the land.
