The Thylacocephala (from the Greek θύλακος or thylakos, meaning "pouch", and κεφαλή or cephalon meaning "head") are a unique grouping of extinct probable mandibulate arthropods, with possible crustacean affinities. As a class they have a short research history, having been erected in the early 1980s. They typically possess a large, laterally flattened carapace that encompasses the entire body. The compound eyes tend to be large and bulbous, and occupy a frontal notch on the carapace. They possess three pairs of large raptorial limbs, and the abdomen bears a battery of small swimming limbs.

  • Thylacocephala(del griego θύλακος thylakos, "bolsa", y κεφαλή (céfalon), "cabeza", es una clase única de artrópodos extintos con posible relación con los crustáceos que vivió entre el Silúrico y el Cretácico. (es)
  • Con il termine tilacocefali (Thylacocephala, dal greco θύλακος thylakos cioè "sacco" e κεφαλή kephalēs "testa") si indica una classe estinta di artropodi a doppio strato. (it)
  • 袋头纲（学名：Thylacocephala，取自希腊语“θύλακος”（袋）和“κεφαλή”（头）的意思），是一类独特的底栖型海生节肢动物。由於袋頭綱是一個在1980年代才建立起來的分類單元，相關物種的研究歷史還很短。 本綱物種具有左右对称的巨大非钙质双瓣，包裹着全身；一对大且圓胖的複眼，陷於頭胸甲前的凹槽中；三对大的，8-16对游泳足，8对鳃以及分节的体节。此前发现的化石材料多数仅保存壳体，因而目前其分类主要依据其壳体形态和表面的壳饰。其化石记录最早可能在寒武纪（如），自志留纪至白垩纪以来多样性一直较低，关于其分类位置和生态特性也一直存在争议。 最早期的袋頭綱物種化石估計出現於晚寒武世，但要到下志留世的海洋群落的出現，才可以肯定牠們的存在。作為一個生物群組，牠們存活至上白堊世。 除此以外，有關袋頭綱物種在解剖學的基礎方面、生活模式及與其他甲殼亞門物種的關係，至今仍有很多不確定性。 (zh)

  • Les thylacocéphales (du grec thylacos, qui signifie «» bourse » ou « poche » et céphalon, qui signifie « tête ») sont un groupe d'arthropodes éteints qui ont peut-être un lien de parenté avec les crustacés. Les recherches concernant cette classe d'arthropodes sont récentes, car ce groupe ne fut décrit qu'au début des années 1980. (fr)

  • Thylacocephala (do grego θύλακος ou thylakos, que significa "bolsa", e κεφαλή ou que significa "cabeça") é um grupo único de artrópodes extintos, com possíveis afinidades aos crustáceos. Como classe, eles têm uma curta história de pesquisa, com início dos anos 1980. Eles normalmente possuem uma grande carapaça achatada lateralmente que abrange todo o corpo. Os olhos compostos tendem a ser grandes e bulbosos, ocupando um entalhe frontal na carapaça. Eles possuem três pares de grandes membros raptoriais, e o abdómen carrega uma série de pequenos membros nadadores. (pt)
