The Messel Pit is famous for its well-preserved fossils, which include semi-aquatic crocodylians such as Asiatosuchus and Diplocynodon. Unlike these crocodylians, Bergisuchus was a small terrestrial hypercarnivore. Rossmann and colleagues speculated extensively about the palaeoecology of Bergisuchus. They suggested that Bergisuchus did not inhabit the fluvial and lacustrine habitats around the Messel and Geiseltal sites. They interpreted the rare, fragmented material as evidence for the bones being transported into these settings from elsewhere, compared to the more abundant and more complete crocodylians from these sites that were well preserved by the local conditions. They further speculated that Bergisuchus may have inhabited drier upland regions from these lakes and rivers, potentially coexisting alongside predatory creodont mammals in the Geiseltal area and avoiding competition with the similarly terrestrial but unrelated planocraniid crocodilians like Boverisuchus.
