QUÉ SIGNIFICA ORDOVICIAN EN INGLÉS
Ordoviciano
El Ordovícico / ɔrdəvɪʃən / es un período y sistema geológico, el segundo de seis de la Era Paleozoica, y cubre el tiempo entre 485.4 ± 1.9 y 443.4 ± 1.5 millones de años atrás. Sigue el período cámbrico y es seguido por el período de Silurian. Charles Lapworth en 1879 definió el Ordovician, nombrado después de la tribu céltica de los Ordovices, para resolver una disputa entre los seguidores de Adán Sedgwick y de Roderick Murchison, que colocaban los mismos lechos de roca en País de Gales del norte en los períodos Cambriano y Siluriano respectivamente . Lapworth, reconociendo que la fauna fósil en los estratos en disputa eran diferentes de los períodos Cambriano o Siluriano, se dieron cuenta de que debían ser colocados en un período propio. Aunque el reconocimiento del período ordovícico fue lento en el Reino Unido, otras áreas del mundo lo aceptaron rápidamente. Recibió sanción internacional en 1960, cuando fue adoptado como un período oficial de la Era Paleozoica por el Congreso Geológico Internacional. La vida siguió floreciendo durante el Ordovícico como lo hizo en el Cámbrico, aunque el final del período estuvo marcado por una significativa extinción en masa.
