==Nomenclature==
''Cenozoic'' derives from the Greek words {{lang|grc-Latn|kainós}} ({{wikt-lang|grc|καινός}} 'new') and {{lang|grc-Latn|zōḗ}} ({{wikt-lang|grc|ζωή}} 'life').<ref name="OnlineEtymologyDict">{{cite dictionary|title=Cenozoic|url=http://www.etymonline.com/index.php?term=Cenozoic&allowed_in_frame=0|dictionary=[[Online Etymology Dictionary]]}}</ref> The name was proposed in 1840 by the British geologist [[John Phillips (geologist)|John Phillips]] (1800–1874), who originally spelled it ''Kainozoic''.<ref>{{cite book |last1=Phillips |first1=John |title=Penny Cyclopaedia of the Society for the Diffusion of Useful Knowledge |volume= 17 |date=1840 |publisher=Charles Knight and Co. |location=London, England |pages=153–154 |chapter-url=https://babel.hathitrust.org/cgi/pt?id=hvd.hn4zr7;view=1up;seq=163 |chapter=Palæozoic series}}  From pp. 153–154: "As many systems or combinations of organic forms as are clearly traceable in the stratified crust of the globe, so many corresponding terms (as Palæozoic, Mesozoic, Kainozoic, &c.) may be made, ...

Although John Phillips originally spelled it as "Kainozoic" in 1840, he spelled it "Cainozoic" a year later:

In name, the Cenozoic ({{lit|new life}}) is comparable to the preceding Mesozoic ('middle life') and Paleozoic ('old life') Eras, as well as to the Proterozoic ('earlier life') Eon.
