O QUE SIGNIFICA SILURIAN EM INGLÊS
siluriano
O siluriano é um período geológico e um sistema que se estende desde o final do Período Ordovícico, cerca de 443,4 ± 1,5 milhão de anos, até o início do período Devoniano, cerca de 419,2 ± 3,2 mya. Tal como acontece com outros períodos geológicos, as camas de pedra que definem o início e o final do período são bem identificadas, mas as datas exatas são incertas por vários milhões de anos. A base do Silurian está em um grande evento de extinção quando 60% das espécies marinhas foram exterminadas. Veja os eventos de extinção Ordovício-Siluriano. Um marco evolutivo significativo durante o Silurian foi a diversificação dos peixes com mandíbulas e ossos. A vida também começou a aparecer em terra sob a forma de pequenas, vasculares que crescem ao lado de lagos, córregos e litorais, e também sob a forma de pequenos artrópodes terrestres. No entanto, a vida terrestre não diversificaria muito e afetaria a paisagem até o Devoniano.
