Abstract

We document temperature-dependent sex determination (TSD) in the Pancake Tortoise (Malacochersus tornieri). The nesting season is biased toward a fall–winter pattern and the embryos have a postovipositional developmental arrest. Males initially grow faster than females, but females are the larger sex. The species does not readily conform to a hypothesis that TSD is adaptively maintained through a direct association of juvenile growth with adult sexual size dimorphism.
