modern mustelids are relatively small predators that hunt small
animals, Megalictis was the prehistoric giant
that was comparable to
modern dogs and big cats. However exactly how big remains a matter of
debate amongst researchers with some saying that Megalictis
relatively light weight at around twenty kilograms, with others
suggesting as much as sixty kilograms if not bigger.
Today Megalictis is often described as being physically similar to the wolverine (Gulo gulo) only much bigger. With this in mind it was probably a generalist predator that could adapt to tackling a variety of different prey that could have also included other small predators as well as herbivores. Because of the physical proportions and joints of the limbs, Megalictis was better suited towards ambush hunting rather than open pursuit. Megalictis probably existed in the same predatory niche as its large relative Ekorus from Africa.
