Lesson plan

Macroplata

Macroplata (meaning "big plate") is an extinct genus of Early Jurassic rhomaleosaurid plesiosaur. 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. It is known from a nearly complete skeleton NHMUK PV R 5488 (formerly BMNH R 5488) from the Blue Lias Formation (Hettangian) of Harbury, Warwickshire, UK. 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.
