Preserved soft tissue of a three-week old cub of a H. latidens found in Siberia in 2020 and described in 2024 indicates that the coat color for juveniles of this species was a black or dark brown color with pale paws and chin. The fur on the corner of the mouth region and back of the neck were longer than on the forelimbs of the mummy. Additionally, the cub had wide, rounded paws, which lacked a carpal pad, and its fur was dense: adaptations to traversing snowy terrain effectively, showcasing these features developed at a young age.
