Calculated ratios of partial brain volume to partial endocast volume (pBV-pEV) for early embryos (Crocodylus acutus), juveniles (Caiman crocodilus) and adults (Caiman crocodilus and larger Crocodylus niloticus) divided into four major sectors: Olf—olfactory, Pros—prosencephalic, Mes—mesencephalic and Rhomb—rhombencephalic
