Cave hyena

life science Maturity 5-7 Next article →

The cave hyena was a powerful apex predator that once roamed across Eurasia.

These animals existed during the Pleistocene epoch, a time defined by many ice ages. They lived in various environments, from Western Europe to East Asia. While they are often called cave hyenas, they were not limited to living in caves. They used caves and sinkholes as dens, but they also lived in open-air areas. They were essential to their ecosystems by controlling the populations of large mammals.

These predators functioned as active hunters rather than simple scavengers. They targeted large ungulates, which are hoofed mammals, such as wild horses and steppe bison. In many European sites, wild horses were a very common prey item. They also hunted reindeer, red deer, and wild boar. When they found much larger animals like woolly mammoths or woolly rhinoceroses, they likely scavenged them. To get the most nutrition, they used their strong jaws to crack open bones. This allowed them to reach the energy-rich marrow inside.

Scientists categorize these animals into two groups: Crocuta spelaea and Crocuta ultima. The spelaea group lived in Europe, while the ultima group lived in Asia. For a long time, researchers treated them as subspecies of the modern African spotted hyena. However, genetic evidence from the nuclear genome tells a different story. The Eurasian populations split from African populations over 1 million years ago. Because they are so genetically different, some authors suggest they should be considered entirely separate species.

Physical differences made the cave hyena much larger than its modern relatives. A 2017 study estimated that they were about 60% heavier than living spotted hyenas. Their bodies also followed Bergmann's rule, a biological principle regarding size and temperature. This rule states that animals in colder climates tend to have larger bodies to stay warm. Consequently, cave hyenas in colder regions were larger than those in temperate areas. Their limb bones were also more robust, meaning they were thicker and shorter.

Their internal anatomy shows unique evolutionary paths as well. The skull of a cave hyena had upper premolars that touched each other. In modern spotted hyenas, there is a gap called a diastema between these teeth. Their brains were also different, being larger and more elongated. However, the front part of their brain was smaller than in modern spotted hyenas. This led some researchers to hypothesize that they might have been less social. Despite this, fossil evidence from cave clusters suggests they likely lived in groups called clans.

The history of the cave hyena is tied to many famous prehistoric figures. They coexisted with both Neanderthals and modern humans during the Pleistocene. There is even evidence that they occasionally consumed the remains of Neanderthals. Their presence is also recorded in ancient cave art, which suggests they had spotted pelts. They were also major competitors with the cave lion. These two apex predators likely engaged in hostile conflicts over carcasses. Evidence shows cave hyena dens sometimes contained the remains of cave lion cubs.

We do not know the exact cause of their extinction. It was likely caused by a combination of several different factors. Climate change may have altered their habitats during the end of the Pleistocene. A decrease in the number of prey animals could have also played a role. Finally, human activity may have impacted their survival. Understanding the cave hyena helps scientists learn how large predators react to changing worlds. Their disappearance marks a major shift in the history of Eurasian ecosystems.
