A Parvancorina-like arthropod from the Cambrian of South China

Article Abstract:

The discoveries of Cambrian Lagerstatten, which preserves mineralizing, as well as nonmineralizing organisms has recently reported a new species of the Cambrain arthropod Skania, which has a close resemblance to the organism Parvancornia and hence establishes a Precambrian root for arthropods. The various results and evidences obtained from their comparative study sets up a new calibration point to estimate the divergence time for the last ancestor of arthropods and priapulids on the basis of molecular clock methods.
