Description

Romania #1889 (1966) – Steppe Bison (Bison priscus)

The steppe bison (Bison priscus), also known as the steppe wisent, was a large, extinct species of bison that lived during the Pleistocene epoch. Here are some key features and facts about the steppe bison:

1. Size and Appearance:
   • Steppe bison were large, with a robust build. They were slightly larger than modern plains bison. Adult males could weigh over a ton.
   • They had distinctive, upward-curving horns, which could span more than two meters. These horns were more widely spaced than those of modern bison.
2. Habitat:
   • Steppe bison were well-adapted to open grassland and steppe environments. They roamed across a vast area, including Europe, Asia, and North America.
3. Diet:
   • Similar to modern bison, steppe bison were herbivores, feeding on grasses and other vegetation. Their adaptability to different grassland environments contributed to their wide distribution.
4. Geographical Range:
   • Fossil evidence indicates that steppe bison inhabited a broad geographic range, from western Europe to Asia. They were also present in North America during the Pleistocene.
5. Social Structure:
   • Like modern bison, steppe bison likely lived in herds, which would have provided them with protection from predators and facilitated grazing.
6. Relationship to Modern Bison:
   • The steppe bison is considered an ancestor to the modern European bison (Bison bonasus) and the American bison (Bison bison). It is part of the evolutionary lineage that led to these extant species.
7. Extinction:
   • Steppe bison, like many megafauna of the Pleistocene, became extinct toward the end of the last Ice Age. The exact reasons for their extinction are not fully clear, but factors such as climate change and human hunting likely played roles.
8. Fossils:
   • Fossils of steppe bison, including skulls and skeletal remains, have been found in various locations, providing important insights into the distribution and evolution of this species.
9. Interactions with Humans:
   • Steppe bison coexisted with early human populations, and there is evidence that they were hunted by humans for their meat, bones, and other resources. Cave paintings and other archaeological evidence depict steppe bison in the context of human activities.

The steppe bison is an important species for understanding the ecology and interactions between large herbivores and their environments during the Pleistocene epoch. Studying their fossils helps reconstruct past ecosystems and contributes to our understanding of the dynamics that shaped the megafaunal communities of that time.
