Les premi\u00e8res plantes et insectes conqui\u00e8rent la terre, de nombreuses nouvelles esp\u00e8ces \u00e9mergent. Le climat est tropi\u00adcal, mais s\u2019est chang\u00e9 rapi\u00adde\u00adment par les plantes : Elles absorbent du dioxide de carbone de l\u2019atmosph\u00e8re, et la temp\u00e9\u00adra\u00adture sur terre dimi\u00adnue. Paral\u00adl\u00e8\u00adle\u00adment, la teneur en oxyg\u00e8ne de l\u2019atmosph\u00e8re augmente. En plus, la chimie des mers change. La Gond\u00adwana (un tr\u00e8s grand conti\u00adnent, en alle\u00admand : \u201eGro\u00df\u00adkon\u00adtinent\u201c) d\u00e9rive vers le p\u00f4le Sud. Tout cela ensemble d\u00e9clenche la deuxieme extinc\u00adtion massive<\/strong> dans l\u2019histoire de la terre.

Le super\u00adcon\u00adti\u00adnent Gond\u00adwana forme une grande masse conti\u00adnen\u00adtale dans l\u2019h\u00e9\u00admi\u00adsph\u00e8re sud. Plus au nord, la Lauren\u00adtie et Baltica s\u2019ap\u00adprochent l\u2019une de l\u2019autre. De grandes parties des conti\u00adnents sont d\u2019abord recou\u00advertes par une mer peu profonde et chaude. Cepen\u00addant, la baisse de temp\u00e9\u00adra\u00adture provo\u00adqu\u00e9e par le m\u00e9ta\u00adbo\u00adlisme des plantes m\u00e8ne vers une nouvelle \u00e8re glaciaire.<\/p>\n","protected":false},"excerpt":{"rendered":"
