Summary:

Pg. 411, 413; 1967 Elem. Geol., p. 411, 413; Edward Hitchcock, 1863, Elem. Geol., p. 411. Dorset limestone. Some of the limestones of Emmons' Taconic contain fossils, apparently identical with certain Devonian forms, hence are regarded as Devonian; and as the place in that series is yet uncertain the name Dorset limestone may be applied to the group, from Dorset Mountain [Pawlet quadrangle], southwestern Vermont, where the whole series is beautifully developed. [This mountain is partly in Rutland County and partly in Bennington County.]
