The Early Devonian is the first of three epochs comprising the Devonian period, corresponding to the Lower Devonian series. It lasted from 419.2 ± 3.2 to 393.3 ± 1.2 and began with the Lochkovian Stage 419.2 ± 3.2 to 410.8 ± 1.2, which was followed by the Pragian from 410.8 ± 3.2 to 407.6 ± 1.2 and then by the Emsian, which lasted until the Middle Devonian began, 393.3± 1.2 million years ago.During this time, the first ammonoids appeared, descending from bactritoid nautiloids. Ammonoids during this time period were simple and differed little from their nautiloid counterparts. These ammonoids belong to the order Agoniatitida, which in later epochs evolved to new ammonoid orders, for example Goniatitida and Clymeniida. This class of cephalopod molluscs would dominate the marine fauna until t

  • Nella scala dei tempi geologici, il Devoniano inferiore rappresenta la prima delle tre epoche o serie stratigrafiche in cui è suddiviso il Devoniano, che a sua volta è il quarto dei sei periodi in cui è suddivisa l'era del Paleozoico. Il Devoniano inferiore è compreso tra 416,0 ± 2,8 e 397,5 ± 2,7 milioni di anni fa (Ma), preceduto dal Pridoli, l'ultima epoca del Siluriano, e seguito dal Devoniano medio. (it)
  • Нижний девон — первый отдел девонской системы. Объединяет породы, отложившиеся в течение раннедевонской эпохи (нижнедевонской эпохи), начавшейся 419,2 ± 2,8 млн лет назад и закончившейся 393,3 ± 2,5 млн лет назад. (ru)

Dzieli się na trzy wieki: lochkow, prag i ems. Chronostratygraficznym odpowiednikiem epoki wczesnego dewonu jest oddział dewon dolny. Dolny dewon dzieli się na trzy piętra: lochkow, prag i ems. (pl)
