trilobite n.【古生物學】三葉蟲。

trilobitic
From the cambrian to the early middle ordovician , the cambrian radiolaria and the early ordovician conodonts of the erlangping trough in the northern part of eqm , and the cambrian trilobites and early ordovician conodonts as well as cephalopods of the northern xichuan shelf in the southern part of eqm belonged to the south china province , while the cambrian trilobites and the early ordovician conodonts of the southern xichuan shelf belonged to the south china province with some elements of the north china province 在寒武紀至中奧陶世早期，東秦嶺北部二郎坪海槽的寒武紀放射蟲和早奧陶世牙形石與東秦嶺南部浙川陸棚北部的寒武紀三葉蟲、早奧陶世牙形石和頭足類屬華南生物省，而浙川陸棚南部的寒武紀三葉蟲和早奧陶世牙形石屬于華南生物省，兼有華北生物省分子。
From the late middle ordovician to the end of ordovician , the cephalopods , gastropods and corals in the erlangping trough , and the conodonts , coral , brachiopods , cephalopods as well as trilobites in the xichuan shelf were from the north china province 在中奧陶世晚期至奧陶紀末，二郎坪海槽的腹足類、頭足類和珊瑚與浙川陸棚的牙形石、珊瑚、腕足類、頭足類和三葉蟲均屬華北生物省。
Each series in the new framework represents approximately the same length of the time and the stage boundaries are defined by significant bio - events as well as cosmopolitan or intercontinental species of trilobites 各統的時間跨度大體相等，階的界線采用重要的生物事件或具有全球對比意義的物種定義。
The new framework , comprising a pre - trilobite series and three trilobite - dominated series , reflects the major evolutional stages of the life on earth during cambrian period 新的劃分方案包括1個“前三葉蟲統”和3個“三葉蟲優勢統” ，反映了寒武紀生命發展的主要階段。

Trilobites were rapidly evolving forms and are of widespread use in biostratigraphic studies . 三葉蟲是進化迅速的種型，并廣泛用在生物地層學的研究上。
Two others of these trilobite fossils have been found in the same area . 在同一地區還發現了另外兩塊這些三葉蟲化石。
