All species of crocodilians that have been studied normally incubate their eggs at temperatures above 27C. Stable temperatures above 27C are not naturally available in the tropical rainforest habitat of paleosuchus trigonatus, and our investigations indicate that its nests are not warmed by the process that have been suggested for nests of other species: insolation, rotting vegetation, and metabolic heat of embryos. Most nests of P. trigonatus are placed at the side of, or on top of, termite mounds. Heat from the termite mound and insulation by the nest material maintain the eggs at about 30C (28.4-32.1C). |
