[From introduction:]
A small collection of scolecodonts, fossil polychaete annelid jaws, is described from the Dundee limestone at Dundee, Michigan and from the Sibley Quarry, Trenton, Michigan. The Dundee limestone is recorded as being the same age as the Marcellus of New York and equivalent to the Delaware limestone of Ohio.
Most of the jaws were very poorly preserved. This is very unusual. When jaws are dissolved out of limestone in a five per cent solution of hydrochloric acid they are nearly always in a very fine state of preservation. Many of the jaws look as though they had been partly eaten away by the acid. Only a small amount of matrix was available at the quarry at Dundee, the type locality of the Dundee limestone. As samples were being taken a dump truck arrived and covered the last exposure of the outcrop. Specimens were not too plentiful at either locality. If additional material was dissolved it is certain that many more forms could be found.
Originally these specimens were collected to make comparisons with a large suite of scolecodonts secured from cuttings from a deep well in the Kawkawlin Field, Michigan, between 2860½ feet and 2937½ feet below the surface. The samples from the well were recorded as Dundee limestone in the log. Studies have shown, Eller (1961), that only one species, Lumbreconerutes cooperi, a long-range form, is common to the Dundee limestone and the well samples.
