| Abstract |
|
Twenty-three stages in the embryonic development of the western painted turtle, Chrysemys picta bellii are described. The staging is based primarily on morphological changes, as well as age and size of the embryo. This is the first complete series showing the embryonic development of an emydid turtle. It documents the external changes of the embryo of Chrysemys picta bellii throughout its development. Yntema ('68) described in detail, the embryonic development of the snapping turtle, Chelydra serpentina. Pasteels ('57) studied gastrulation in three genera of turtles, Clemmys, Chrysemys, and Pseudemys but did not describe later stages.
