Analysis of a large sample of bones from mound 1, representing the Cherla phase, has been completed, with the remainder of the collection nearly finished. The vertebrate faunal remains from mound 1 are dominated by fish such as catfish and gar. The great numbers of catfish and other estuarine species as snook and snapper suggest a focus on riverine or estuarine fishing.
Amphibians are present too but in relatively low numbers.
Iguanas and mud turtles are by far the most common reptiles, but snakes, other lizards, and turtles are present as well. At least one crocodile is represented, accounting for as much meat as almost all of the other reptiles combined. Again, an estuarine and swamp emphasis is suggested. The sample from mound 1 has yielded a diverse mammal fauna. Rodents, followed by armadillos and rabbits, dominate.
