Acanthomeridion is an extinct arthropod found in the Chengjiang fauna deposits of China.[1] In 1997, it was placed in its own, monotypic family, Acanthomeridiidae.[2] It is known from eight specimens, all found in China.[3]
Acanthomeridion was a 35 mm-long animal, with 11 segments ending in rear-facing spines. The head features free cheeks separated by the rest of the head by sutures. This is analogous with trilobites. Otherwise, affinities are unclear. [3]
