Ramfowl (Ariavis montani) male (& female head). Males of this genus have wide and thick bone and ceratin crests that function much the same way as mountain sheep horns: the males will bang their horny crests together to establish dominance.
The snowstrek (Villopluma rostricornis) isn't a true strek but represents a separate lineage that split from protosuinavids during the late Miocene. These animals inhabit the freezing arctotitan steppes of the holarctic. This freezing habitat has lead to certain specializations, such as the flat horn-like crest found in both sexes, which can be used to dig for feed from under a thin cover of snow, and the enlargened nasal cavity that forms a very distinct bump on both sides of the head.
The golden jackalope is the largest Struthiodactylus species in the Old World weighing up to 105 kg. It is found in subsaharan Africa.
The cheetaur (Tauropanthera velox) could be considered as the pinnacle of pantherbull evolution. These predators rank among the fastest creatures on spec, having evolved side by side with the nigh equally speedy jackalopes. This african predator is also the smallest of the priscataurs, only 4 meters long (half of this consisting of the tail) apparently also as an adaptation to hunt small and fast moving game. Cheetaurs are usually loners, but are sometimes known to cooperate with siblings or other closely related individuals. Despite this fact, a cheetaur will drive away or kill an unrelated individual if it catches one trespassing in its territory.
