Titanoboa
Titanoboa lived in the first recorded tropical forest in South America. It shared the ecosystem with large Crocodylomorpha and large turtles. The paleogeography of the late Paleocene was a sheltered paralic (coastal) swamp, with an open connection to the proto-Caribbean in the north. In this environment tropical aquatic ferns like Salvinia flourished. The ferns were found as fossils in the Bogotá Formation and the Palermo Formation.
