Verniers et al. (1995) have recently produced a very valuable global biozonation for the Silurian based on Chitinozoa. It should be noted, however, that the Llandovery-Wenlock boundary as defined in the Chitinozoa biozonal scheme does not correlate precisely with the boundary in the recently published 'generalized graptolite zonal sequence defining Silurian time intervals for global paleogeographic studies' (Koren' et al. 1995) ratified by the Subcommission on Silurian Stratigraphy.
