...J. Jansonius; J. H. Craig ABSTRACT I. Scolecodonts (dispersed chitinous jaws of fossil marine polychaetous annelids) have significant potential for stratigraphic application in Paleozoic strata; they are resistant to acids, oxidation, thermal alteration, and recrystallization of carbonate matrix...

..., together with some inferences from those facts. Grayish-green, soft, plastic shale occurs from 2,090 to 2,168 feet. No spores are present, but fragments suggesting annelid jaws were found in this shale, which may indicate its age as Richmond; therefore, the shale from 2,090 to 2,168 feet is correlated...

.... Scolecodonts (the jaws of polychaete annelid worms) are microfossils that occur in great abundance in many Ordovician rocks. Nevertheless, this microfossil group has largely been neglected and occurrences are usually at best merely mentioned. During some 150 years of study, approximately 40 papers (including...

... detail in order to achieve more precise biostratigraphical age determinations of the mud-mounds (see below).

... two sets of paragnaths are present (Fig. 6A). The function of the paragnaths is not really clear. However, the fact that paragnathal e ements are worn and damaged suggests that they may have been used to abrade the rock through which the annelid is boring. If the jaws were retracted, as appears...

..., the Ordovician annelid record is crucial to understanding the evolution of the group. The scolecodont record suggests substantial diversification of jawed polychaetes during the Ordovician Period (Hints and Eriksson, 2007 ). Machaeridians (now known to be annelids; Vinther et al., 2008 ) also appear to have...
