三葉蟲是距今5.6億年前的寒武紀就出現(xiàn)的最有代表性的遠古動物，是節(jié)肢動物的一種，全身明顯分為頭、胸、尾三部分，背甲堅硬，背甲為兩條背溝縱向分為大致相等的三片——一個軸葉和兩個肋葉，因此名為三葉蟲。
Trilobites are the most representative ancient animals that appeared in the Cambrian Period 560 million years ago. They are one of the arthropods. Their whole body is obviously divided into three parts: head, chest and tail. Their dorsal carapace is hard. Their dorsal carapace is divided longitudinally into three roughly equal parts, one axillary leaf and two costal leaves, so they are called trilobites.
三葉蟲在5億～4.3億年前發(fā)展到高峰，至2.4億年前的二疊紀完全滅絕，前后在地球上生存了3.2億多年，可見這是一類生命力極強的生物。在漫長的時間長河中，它們演化出繁多的種類，有的長達70厘米，有的只有2毫米。
Trilobites reached a peak between 500 million and 430 million years ago, and completely disappeared in the Permian period 240 million years ago. They have survived on the earth for more than 320 million years, which shows that they are a kind of highly viable organisms. Over a long period of time, they have evolved into a variety of species, some as long as 70 cm, some only 2 mm.
三葉蟲是我國科學家系統(tǒng)研究化石早發(fā)端的門類之一，也是一種著名度相對較高的古生物化石。在距今5.4億年前的寒武紀時代，三葉蟲曾是其時海洋的主宰。由于身體縱向上被分為三個部分——中央的軸部和兩側(cè)的肋葉，故名三葉蟲;同時，三葉蟲橫向上亦被分為頭、胸、尾三個部分。這些身體巨細從2毫米到70厘米不等的三葉蟲在古生代早期為繁盛，種類極為富厚，全球各地均有漫衍。現(xiàn)在，在古生物地層學、演化生物學、古生物系統(tǒng)學、古地理學、板塊結(jié)構(gòu)學等研究領域，三葉蟲均具有主要意義。
Trilobites are one of the earliest phylogenetic groups of fossils systematically studied by Chinese scientists. They are also a relatively well-known paleontological fossil. In the Cambrian era 540 million years ago, Trilobites were the dominant marine species. Because the body is divided into three parts longitudinally - the axis of the center and the rib leaves on both sides, it is called trilobite. At the same time, the trilobite is also divided into three parts horizontally: head, chest and tail. These trilobites, which ranged in size from 2 mm to 70 cm, flourished in the early Paleozoic, with abundant species and spread throughout the world. At present, Trilobites are of great significance in the fields of paleobiostratigraphy, evolutionary biology, paleontology, paleogeography and plate tectonics.
隨著市場對化石的收藏熱度來看，三葉蟲化石已經(jīng)不是單單的收藏那么簡單了，化石對于收藏愛好者和化石投資者來說已經(jīng)源源不是簡單的喜歡和研究那么簡單了，化石源于他的稀有和對于上冰河時期地球早期所發(fā)生的變故而遺留下了的億萬年標本進而變成了化石，所以化石已經(jīng)不單單是只有研究價值而已，因為他的稀有和市場對他們的評估已經(jīng)是非常高。
With the heat of fossil collection in the market, the collection of trilobite fossils is not so simple. Fossils for collectors and fossil investors are not so simple to like and study. Fossils are derived from his rarity and from the changes that took place in the early Earth during the Upper Ice Age. The remains of hundreds of millions of years of specimens have turned into fossils, so fossils are not only of research value, because their rarity and market evaluation are already very high.
