Paradoxides is a genus of large to very large trilobite found throughout the world during the Middle Cambrian period. One record-breaking specimen of Paradoxides davidis, described by John William Salter in 1863, is 37 cm (15 in). The cephalon was semicircular with free cheeks ending in long, narrow, recurved spines. Eyes were crescent shaped providing an almost 360° view, but only in the horizontal plane. Its elongate thorax was composed of 19-21 segments and adorned with longish, recurved pleural spines. Its pygidium was comparatively small. Paradoxides is a characteristic Middle-Cambrian trilobite of the 'Atlantic' (Avalonian) fauna. Avalonian rocks were deposited near a small continent called Avalonia in the Paleozoic Iapetus Ocean. Avalonian beds are now in a narrow strip along the E

  • Paradoxides is een uitgestorven geslacht van de trilobieten en een van de best bekende en grootste daarvan, met een lengte tot 37 cm. Ze leefden in het Midden-Cambrium (540 miljoen jaar geleden). Paradoxides is een geslacht van grote tot zeer grote trilobieten die over de hele wereld worden gevonden. Een recordbrekend exemplaar van Paradoxides davidis is 37 cm. De naam van het geslacht werd voor het eerst gepubliceerd in 1822 door Alexandre Brongniart. In de protoloog beschreef hij de soorten Paradoxides tessini, P. spinulosus, P. scaraboides, P. gibbosus en P. laciniatus. (nl)
  • 奇異蟲（學名：Paradoxides）是生存於寒武紀的一屬三葉蟲，生活在大陸棚的泥中。這類三葉蟲比任何生存在寒武紀的其他屬三葉蟲都還要大——最大的個體可長達一公尺。牠們有寬闊的頭部、小型的尾和呈圓錐狀逐漸變小的長形胸部，並有隨其成長而增加的胸節。牠們的眼睛很發達，眉間的前部裂片呈扁平狀，側面頰部則延長為棘。 (zh)
