Archeleons, the almighty Henodus, and other turtles/turtle-like creatures crawl onto the beach annually to lay their eggs. They don't drop them in the sea.

Plesiosaurs, Liopleurodons, Mosasaurs, and Ichthyosaurs give birth to live young.

The only ocean-dwelling animals that deposit their eggs in the water are sharks, fish, and mollusks.
