Noah's Ark Possibility Project (NAPP)
Table 10 is intended to provide a rough estimate of the average weight of adult prehistoric extinct birds. This may not be the right criteria as the Bible does not state that the animals on the ark were adults, almost adults, adolescents, preadolescents, etc. Age may make a significant difference in weight especially with those animals that are said to keep growing all their lives.
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 10 is based not on species but on genera, the grouping one step above species. Of course genera might not be the correct criteria either.
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 total number of prehistoric extinct genera is uncertain but based on the information in this table could easily have been up to 100 or more. For now 125 genera will be used in the calculations. Weights for 78 genera have been estimated as indicated in this table. The rough estimate of the average weight of prehistoric extinct birds was then calculated by dividing the sum of the individual genera weights in the table by 78.

1. The first part of the above genera to pediornis came from https://en.wikipedia.org/wiki/List_of_Late_Quaternary_prehistoric_bird_species
2. Extinct species of extant genera and birds of undetermined genera are not included.
3. Weight information was often lacking in
a. Where an animal of comparable size was mentioned and a weight estimate was available for that animal, the weight estimate
for the comparable animal was used as indicated by "a" in this table.
b. Where more than one weight is given in a reference, the lowest
value was used as indicated by "b" in this table.
c. When relative size to another animal only was given, then the weight was estimated
based on the size statement as indicated by "c" in this table.
d. Where a maximum weight only was given, 75 percent of the maximum
weight was used as indicated by "f" in this table.
e. When length and/or height but not weight information was available in the references,
then weights of birds of the same approximate size were used as indicated by "g" in the table.
