Crocodilian

1989, Walter P. Coombs, Jr., Modern analogs for dinosaur nesting and parental behavior, James Orville Farlow (editor), Paleobiology of the Dinosaurs, Issue 238, page 47, Mound-nesting crocodilians and megapodes appear to be indifferent to nest-site parameters, but susceptibility of crocodilian mound nests to predation or drowning may be altered by site selection.

Superb predators, the crocodilians are reptiles, and the only survivors of the archosaurs that included dinosaurs.

Crocodilians are essentially lizard-like in basic shape and are adapted to a largely aquatic life. ln water, they hunt and eat their prey and advertise their size and location by bellowing.

However, it is possible that baby titanoboas and Titanoboa eggs were preyed upon by the same crocodilians the adults ate.
