This is a large sub-adult hyena skull (Dinocrocuta), the rival of the saber-toothed tiger. The whole head is about 30 cm. It's hard to find such a complete skull. This *Dinocrocuta* is a subadult, so its canines have just erupted, making it a very rare fossil to observe. We will use very good packaging materials for packaging. This fossil can be displayed directly without a display stand. The largest species, D. gigantea, is known to have reached head-to-body lengths and shoulder heights of 1.9 m (6.2 ft) and 1.3 m (4.3 ft) for the largest individuals, with total skull lengths of 43 cm (17 in). In terms of weight, it was originally stated to have weighed up to 380 kg (840 lb). However, the method used has been known to overestimate the masses of extinct carnivorans. Smaller individuals, such as the holotype specimen, hit around 200 kg (440 lb). Based on this smaller specimen, the largest specimens of this species would have reached weights close to 300 kg (661 lb), which rivals the mass of the largest tiger sub-species, and is only exceeded by Smilodon populator, Panthera atrox, and several amphicyonids and ursids. The other species were smaller in size, but still quite large compared to hyena species alive today.
