Macroplata
 Macroplata (mack-roh-PLAH-tah) meaning (big plate) is an extinct genus of Early Jurassic basal plesiosaur which grew up to 4.5 metres (15 ft) in length. Like other plesiosaurs Macroplata probably lived on a diet of fish using its sharp needle-like teeth to catch prey. Its shoulder bones were fairly large indicating a powerful forward stroke for fast swimming.
