Noah's Ark Possibility Project (NAPP)
Table 2 provides a rough estimate of the total weight of 9,615 species of adult male and female reptiles alive today and a calculated overall average weight for these adult reptiles based on this total. Crocodilia and sea serpents are not included in the number of species above and calculations as the survival of these marine species in a flood probably would not require an ark.
Estimates are based on as large of sampling as practical using primarily online resources. As adult reptile weights for a particular species can vary considerably depending on age, sex, locality, contents of digestive system, and other factors, averaging became the preferred method. Rough average adult weights were calculated for each sample species in a group (i.e order, suborder, family, or genus). Then these rough average adult weights were averaged for the group. This group average then was multiplied with few exceptions times the number of species in the group times two to give a total weight for male and female couples in the group. All total weights for the groups were then added together to give the total weight of the female and male adult reptiles. The rough overall average weight per reptile was then determined by dividing the latter total weight first by two and then by total number of reptile species, excluding Crocodilia and sea serpents.
