Pygmy hippopotamus occur. The common hippopotamus gives birth and mates only in the water, but pygmy hippos mate and give birth on both land and water. Young pygmy hippos can swim almost immediately. At birth, pygmy hippos weigh 4.5–6.2 kg (9.9–13.7 lb) with males weighing about 0.25 kg (0.55 lb) more than females. Pygmy hippos are fully weaned between six and eight months of age; before weaning they do not accompany their mother when she leaves the water to forage, but instead hide in the water by themselves. The mother returns to the hiding spot about three times a day and calls
Jugulator (mammal) displayed these behaviours. "Jugulator" occurs in the mid-Cretaceous deposits of the Cedar Mountain Formation, where several of North America's more iconic dinosaurs like "Utahraptor" and "Cedarosaurus" occur. A large variety of mammal species are known from here as well, including other eutriconodonts like "Astroconodon" and "Corviconodon" as well as multituberculates like "Cedaromys" and "Janumys" and several therian mammals such as "Montanalestes" and "Atokatheridium". These diverse mammal faunas offer a transition from dominant taxa in the Early Cretaceous and the multituberculate and therian dominated laurasian mammalian faunas of the Late Cretaceous. Jugulator (mammal) Jugulator is a genus of extinct mammal from
