Geology of the Area
CONDITION OF STRATA AND FOSSILS

The footprints described in this paper were found in the northwestern corner of the Narragansett basin after a report on this region by Messrs Shaler and Foerste and the writer had gone to press.* In this report it is brought out that a small part of the Narragansett basin is not more metamorphosed than the Paleozoic rocks of the New York state system, and that in this tract the conditions for the preservation of fossils are peculiarly good. In the region to the south and east the Carboniferous strata have been folded, and particularly toward the south metamorphosed to such an extent that the organic contents of the beds have been largely distorted beyond recognition or actually effaced.

DISTRIBUTION OF METAMORPHISM

The contrast between the Wrentham area and the remainder of the basin is very great in regard to the metamorphism . . .
