Time period: Danian of the Paleocene through to the Messinian of the Miocene.
Fossil representation: Several individuals,‭ ‬though often of incomplete skull and jaw remains.

       Eocaiman is so named due to the similarity to the modern day Caiman of South America,‭ ‬though Eocaiman appears much earlier in the fossil record,‭ ‬with the earliest examples going all,‭ ‬the way back to the first stage of the Paleocene.‭ ‬Henceforth,‭ ‬Eocaiman is expected to‭ ‬have been quite similar to its modern day cousins,‭ ‬hunting in the river systems of ancient South America for fish and other small terrestrial vertebrates.‭ ‬Eocaiman however were not even close to the top crocodylian predators of the time,‭ ‬with genera such as Mourasuchus and Purussaurus easily dwarfing Eocaiman in terms of physical size.
