Macroplata (meaning "big plate") is an extinct genus of Early Jurassic rhomaleosaurid plesiosaur which grew up to 4.65 metres (15.3 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. Macroplata also had a relatively long neck, twice the length of the skull, in contrast to pliosaurs.[1]

A different species, Macroplata longirostris (previously called Plesiosaurus longirostris), which lived somewhat later, during the Toarcian stage, was also included in the genus; however, in 2011, Benson et al. reclassified it as a pliosaurid in the genus Hauffiosaurus, H. longirostris.[2]
