Noah's Ark Possibility Project (NAPP)
Table 9a is intended to provide a rough estimate of the total weight of extinct prehistoric adult male and female reptiles, except dinosaurs, that may have been on the ark. In making this estimate, maximum possible weight is not the criteria but the possibility of a certain weight meeting the biblical criteria and what is observable. The biblical criteria for loading the animals on the ark is two of every kind of living animal, male and female, and seven of every kind of living clean animal, male and female. The use of kind here most likely does not agree with the poorly defined term species. Micro evolution (variation within a kind) takes place all the time and it is unlikely that God would consider these variants as different kinds of living flesh. For this reason, Table 9a is based not on species but on genera, the grouping one step above species. Of course genera might not be the correct criteria either.
Another important factor is extinctions that may have occurred prior to the flood. Noah is told to bring two of every living thing of all flesh into the ark. Based on what we experience today with overhunting, there is a high probability that there were many extinctions before the flood. If a kind had become extinct before the flood, it does not fall under the definition of living flesh and would be absent from the ark. No attempt has been made here to exclude any extinctions.
The number of prehistoric extinct reptile genera, except marine reptiles and dinosaurs, estimated is 384 genera based on information from Wikipedia. The total weight of these genera was then roughly estimated and from this estimate an overall average weight calculated.
Prehistoric marine reptiles are not included in the number of genera 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 Wikipedia online resources. As adult reptile weights for a particular genus can vary considerably depending on age, sex, and other factors, averaging became the preferred method. Rough average adult weights were calculated for each sample genus in a group (i.e. order, suborder, or family). Then these rough average adult weights were averaged for the group. This group average then was multiplied times the number of genera 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 genera, excluding marine reptiles.
