化石拍賣（私人收藏）

衣蛛目在古生物学中占有著名地位，因为它们是极少数在被发现活着之前就已化石化的生物之一。如今仍存的物种极为怕光且隐秘，但它们的祖先在古生代曾经繁盛且多样。 

大约四分之三的已知衣蛛目化石物种来自晚石炭纪的煤层，主要分布在欧洲和北美。古生物学家将这些古代成员归入已灭绝的亚目Palaeoricinulei。 

向树木转移：被琥珀所保存的灭绝成员（如隶属于亚目Primoricinulei的Hirsutisoma grimaldii）显示了不同的生态位。基于它们毛茸茸的体表结构和腿部适应性，科学家认为在白垩纪时期它们生活在树皮上，作为树栖捕食者，而非仍埋在土壤中。 

Ricinulei是一种体积非常小、神秘的蛛形纲目。常被称为“披帽蛛”，尽管它们既不是蜘蛛也不是蜱虫。它们是以落叶层或洞穴为栖的捕食性节肢动物，通常长度小于1厘米。 

时期：白垩纪（约一亿年前）
地点：缅甸哈卡温谷

  The Order Ricinulei holds a famous place in paleontology because they are one of the very few organisms discovered as fossils before they were ever found alive. While today's surviving species are highly light-avoiding and secretive, their ancestors were once thriving and diverse during the Paleozoic Era.
  
  Roughly three-quarters of all known Ricinulei fossil species come from the Late Carboniferous coal measures, primarily found in Europe and North America. Paleontologists group these ancient members into the extinct suborder Palaeoricinulei.

  A Shift to the Trees: Extinct members preserved in amber (such as Hirsutisoma grimaldii under the suborder Primoricinulei) show a different ecological niche. Based on their hairy body structures and leg adaptations, scientists believe that during the Cretaceous, they lived on tree bark as arboreal predators, rather than staying buried in the soil.

  Ricinulei is a very small, mysterious order of arachnids. They are commonly known as "hooded tickspiders," although they are neither true spiders nor ticks. They are predatory arthropods that live in leaf litter or caves, usually measuring less than 1 centimeter in length.
