What is Mesozoic marine revolution?
The '''Mesozoic marine revolution''' was the great increase in [[sea-floor]] predators that ate [[shellfish]]. The term was used by Vermeij, a paleontologist who spent years investigating changes in seafloor invertebrates.<ref name=Vermeij1977>{{cite journal| author = Vermeij G.J.| date = 1977 | title = The Mesozoic marine revolution; evidence from snails, predators and grazers| journal = Paleobiology| volume = 3| issue = 3 | pages = 245–258| doi = 10.1017/S0094837300005352 | jstor = 2400374 | s2cid = 54742050 | url = https://www.jstor.org/pss/2400374 | access-date = 2008-05-13}}</ref><ref name=Stanley2008>{{cite journal| author = Stanley S.M.| year = 2008| title = Predation defeats competition on the seafloor| journal = Paleobiology| volume = 34| pages = 1–21| doi = 10.1666/07026.1| s2cid = 83713101}}</ref><ref>{{cite journal|author=Stanley SM |year=1974 |title=What has happened to the articulate brachiopods? |journal=GSA Abstracts with Programs |volume=8|pages=966–967}}</ref> There was a notable change in sea-floor life between the [[Palaeozoic]] [[fauna]] and the modern fauna.
