琥珀的奇幻世界

纓尾目是現存昆蟲中最原始的族群，最早可追溯至距今三億九千萬年前的泥盆紀中期，沒有翅膀，屬於無變態昆蟲。這個目裡有「石蛃」與「衣魚」這兩科，兩者外形相似，都有三根長長的尾毛，都是琥珀化石中少見的昆蟲，其中衣魚較石蛃更為罕見。

Thysanura is the most primitive group of the existing insects, dating back as the earliest as the middle Devonian 390 million years ago. Without wings, they are ametabolous insects including families of bristletails and silverfish. These two look similar with 3 long cerci, and both are rarely seen in amber fossils. Silverfish is even rarer than bristletail.
