Caloric protein and fat contribution of representative animals (and see Table S1).

Table Notes.
1Excluding brain, heart, liver, tongue together comprising approximately 5% of edible tissue by weight ([157]:1626).
2All numbers for fat with the exception of the elephant are based on Bunn and Ezzo ([3]:370 after Ledger ([87]). Cancellous fat is excluded.
3Fat yield = 82% of fat weight. Based on Cordain et al. ([88]:152) after Crawford et al. ([89]).
4Protein content based on Ledger ([87]:299).
5Elephant weight based on Christiansen ([158]: Table 7); fat to protein proportion based on buffalo here. Due to lack of data regarding fat and protein content of elephants, and ancients one at that, our calculations are based on the next largest terrestrial animal mentioned by Ledger ([87]) – the buffalo. As the proportion of fat increase with the size of the animal ([159]), the estimated fat content and total calories supplied by the elephant are likely underestimated.
