The armored catfish (cascudo), piranha, tambaqui, marbled swamp eel (muçum), ripsaw catfish (cujuba), pirarucu and many other fish. The diet of pre-colonial indigenous peoples in the past was much more diverse than our diet today. By studying thousands of fish bone remains, archaeologist Gabriela Prestes has discovered that various animal species were consumed in ancient Amazonian villages. Many of the fish once eaten (eels, piranhas, rays) are part of recipes we no longer know today but can recover. The project will study the sambaquis or middens of the Amazon, which are large mounds made of shells and earth and have been occupied for thousands of years. Thanks to the exceptional preservation of plant and animal remains in these places, each layer of a sambaqui is like a book that tells a chapter of the history of the peoples who occupied the floodplains and rivers of the Amazon.
