Petrified wood has been found in South Britain as erratics in glacial till and recorded with vague locality descriptions by Brace (1823), Robinson (1825), Hitchcock (1828), Hobbs (1901).

Brace's (1823) perhaps first description is very good:

Agatized Wood, in the south part of the town—found by Dr. Smith. It presents distinct branches, with their knots, bark and ligneous layers often visible, sometimes four or five inches in diameter. It is principally hornstone; its cavities are lined with minute quartz crystals and layers of chalcedony. It is of a grey or black color—specific gravity 2.6.

Robinson (1825) noted it was found abundantly "3 m. S. W. from Smith's inn".

According to Hickey, Hu and Skinner (2011), the source is apparently from Late Triassic sediments (South Britain Formation) in the Pomperaug Basin, from an area about 300 yards long and half a mile wide along Horse Fence Hill Road, stratigraphically just above the basin's angular unconformity with metamorphic rocks. They named the 201 million year old conifer trees Pomperaugoxylon connecticutense. This includes a >90-kg specimen found in glacial till on the steep south bank of the Housatonic river in the Cedarhurst area of Newtown, S33E from the Horse Fence Hill Road site, which is in line with local glacial striations.
