A hypermassage is an animal whose food composition is more than 70% meat. Meat can be obtained either by active predation or by scavenging. The rest of the diet is made up of other ingredients, such as mushrooms or fruit. Living hypermassivores include crocodiles, owls, squirrels, eagles, vultures, felines (all cats, including domestic cats, are hypermassivores), dolphins, snakes, spiders, scorpions, mantises, some carnivorous fish, and most sharks. Thus, a hypermassage does not have to be a top predator. For example, salmon are the exclusive carnivores, yet they become the prey of many predators throughout their lives. Related species can often have a completely different diet - an example is the polar bear (90% meat), unlike the grizzly bear with only 10% meat. The two species separated from each other only 150,000 years ago. In paleobiology, the term hypermassage is used to describe animals in which the teeth are adapted for slicing rather than grinding and crushing. Many prehistoric mammals belonging to the Carnivoramorpha clade (ie carnivores and their tribal relatives), along with creodonts and some mammals of the older group Cimolesta, were hypermassive. Theropod dinosaurs, such as Tyrannosaurus rex, were also strict carnivores. Large species of top hypermassage eaters often appear in fossil records in response to the decline or extinction of older dominant hypermassage groups. Although, at the individual level, a trend towards increasing the size of carnivores may be beneficial, a similar extreme specialization leads to a reduction in population density and thus to a greater susceptibility to extinction. As a result of these opposing forces, fossil records are dominated by the consecutive pros of top hypermassage, which first diversify, later die out, and gradually replace over time.
