Overview

The Paleozoic deposits of New York record a portion of the history of ancestral North America or Laurentia during some 200 million years of geologic time (Figure 4.IB), and as such, they cannot be understood in isolation from the region as a whole. During this interval, present-day New York lay generally in southern subtropical to warm temperate latitudes, with the equator running approximately centrally through Laurentia. Climates ranged from hot and arid to warm and humid during this time.
