These species have a palaeogeographically widespread transoceanic 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. %G English %2 https://insu.hal.science/insu-03188984/document %2 https://insu.hal.science/insu-03188984/file/bsgf_2020_191_32_190073.pdf %L insu-03188984 %U https://insu.hal.science/insu-03188984 %~ UNIV-ST-ETIENNE %~ ENS-LYON %~ INSU %~ CNRS %~ UNIV-LYON1 %~ LGL-TPE %~ UDL %~ UNIV-LYON
