Subdivisão do Paleogeno de acordo com a Tabela Cronoestratigráfica Internacional versão 2015/1 da Comissão Internacional sobre Estratigrafia.

Eoceno é a segunda época da era Cenozoica, está compreendida entre cerca de há 56 milhões de anos e cerca de há 34 milhões de anos.^[1]^[2]^[3]^[4] O Eoceno sucede o Paleoceno e precede o Oligoceno. O nome Eoceno vem do grego eos (ἠώς, "amanhecer") e kainos (καινός, "novo").^[5]^[6] Divide-se nas idades Ypresiana, Lutetiana, Bartoniana e Priaboniana, da mais antiga para a mais recente. Foi durante este período que se formaram algumas das mais importantes cordilheiras de nosso planeta, tais como os Alpes e o Himalaia.
