       Chriacus has a curious mix of features since it was a plantigrade quadruped that had hind legs suitable to climbing and fore legs suitable for digging.‭ ‬This has led to Chriacus being described as a raccoon-like animal,‭ ‬a generalist that could adapt its foraging behaviour to search for whatever food was available.‭ ‬This flexibility is reflected in the popular depiction of Chriacus as an omnivore,‭ ‬eating both plants and small animals,‭ ‬as well as possibly raiding nests for eggs and chicks.
