High Quality Content by WIKIPEDIA articles! The wood turtle (Glyptemys insculpta) is a turtle endemic to North America. It is in the genus Glyptemys, a designation given to only one other turtle: the bog turtle. The wood turtle reaches a carapace length of 14 to 20 centimeters (5.5 to 7.9 in), its defining characteristic being the pyramidal pattern on its upper shell. Morphologically, it is similar to the bog turtle, spotted turtle, and Blanding`s Turtle. The wood turtle exists in a broad range extending from Nova Scotia in the north (and east) to Minnesota in the west and Virginia in the south. In the past, it was forced south by encroaching glaciers: skeletal remains have been found as far south as Georgia.
