Strabopida Strabopida ia an order within the taxonomic clade or subdivision of arachnomorpha. It is described by X. Hou and J. Bergström in Arthropods of the Lower Cambrian Chengjiang Fauna, Southwest China, published in Fossils and Strata, No.45, Scandinavian University Press, Oslo, 22nd of December, 1997. It is one one of the five most important taxanomic groups within Arachnomorpha, along with Chelicerata, Cheloniellida, Trilobita and Aglaspidida. The species of this taxon are now extinct, but they would have lived in the Cambrian period, approximately 540 to 490 million years ago, and would probably have evolved as a result of the cambrian explosion.
