A skeletal reconstruction of Whatcheeria deltae (credit B. Otoo). This study made thin-sections of Whatcheeria thigh bones (femora) including a juvenile femur that revealed a type of bone that is associated with elevated growth rates. In histological section and under polarized light, this disorganized tissue in juvenile Whatcheeria femora suggest that this animal grew quickly early in its lifetime.
