Discussion
- Males are assumed not to differ from females
- Temperatures are guessed and assumed to vary as T_mean+25*sin(2*pi*(t+100)/365 with T_mean - 15 C for B and 10 C for C
- Aging in tL and tW data based on rattle segments, which is generally considered to be unreliable
Facts
- Sex is determined by incubation temperature (Ref: retileDB)
- Females somewhat smaller than males (Ref: Beau1995)
