Razlika između verzija stranice "Geološka era"

'''Geološka era''' je jedinica [[geološka vremenska skala|geološke vremenske skale]] na temelju koje se [[fanerozoik|fanerozojski]] [[eon (geologija)|eon]] dijeli na tri manja perioda<ref>Short, N.M.

Te su ere razdvojene vremenskim granicama katastrofalnog [[izumiranje|izumiranja]]: [[Izumiranje perm-trijas]] između [[paleozoik]]a i [[mezozoik]],a [[izumiranje kreda-tercijar]] smatra se granicom između mezozoika i [[kenozoik]]a. Postoje dokazi da je katastrofalni udar [[meteorit]]a igrao ulogu u određivanju granica između era.

[[Hadij]], [[arhaik]] i [[proterozoik]] čine neformalne [[prekambrij|prakambrijske ere]]. U geološkoj historiji, one traju četiri milijarde godina prije nastanka tvrdoljušturnih životinja.
