【 摘 要 】

Four species of myodocope ostracod are documented from the Silurian Ludlow Series of the Aburtkan gorge on the southern slope of Dzhalpak Mountain, Uzbekistan: namely, Parabolbozoe bohemica (Barrande, 1872), Bolbozoe anomala Barrande, 1872, Silurocypridina calva Perrier, Vannier and Siveter, 2011 and Richteria migrans (Barrande, 1872). These species have a palaeogeographically widespread trans-oceanic distribution, which supports the notion that Silurian myodocopes signify the earliest zooplanktonic ostracods. Richteria migrans (Barrande, 1872), in particular, provides a precise intercontinental biostratigraphic marker that identifies rocks of the upper Gorstian to upper Ludfordian stages.
