... ( Klapper and Philip, 1971 ; Bergman, 1989 ; Eriksson and Bergman, 1998 , and references therein). The majority of the Paleozoic scolecodonts are interpreted as belonging to polychaetes of the extant order Eunicida ( Kielan-Jaworowska, 1966 ; Szaniawski, 1996 ), and it was not until very recently...

... belong to the order Eunicida (Szaniawski 1996 ). Scolecodonts were described for the first time by Eichwald ( 1854 ) from the Baltic region. Since then, the literature has been accumulating on scolecodonts in Palaeozoic strata, particularly from Europe, North America and more Gondwanan areas (e.g. Hinde...

... ( Hints & Eriksson, 2007 ). The majority of the Recent Eunicida live in shallow-water sediments, especially near shore, but some are pelagic ( Szaniawski, 1996 ). Fossil jawed polychaetes were facies controlled in their distribution; the abundance and taxonomic diversity of scolecodonts increases...

Hence, these jaws are not part of multi-element jaw apparatuses typical of members of the order Eunicida, to which all of Hinde's (1879) , and most Paleozoic, scolecodonts belong.
