Description
B. schoetensacki was generally similar to extant European bison in shape although there could have been morphological variations among European bisons during late Early Pleistocene and Early Holocene.
In comparison to B. priscus, B. schoetensacki was either smaller or similar in size but with slenderer leg bones and metapodials, and had shorter and differently shaped horns.

Diet
Despite its common name, B. schoetensacki was probably not a mix-feeder, like the extant American wood bison. Instead, dental mesowear of the species shows similar pattern to that of extant European bison, a grazer.
Paleobiology
During the Late Early and Early Middle Pleistocene, B. schoetensacki was the most common large bovid in Europe. Fossils have been obtained from Czech Republic, England, France, Germany, Greece, Italy, Moldova, Russia, Spain, and mass excavations from the Paleolithic site of Isernia in Italy, dating back to around 700,000 years ago, indicate B. schoetensacki was the most heavily targeted animal by human hunters, as European bison likely didn't inhabit the Italian and Iberian Peninsulas.
Ranges of B. schoetensacki and steppe bison presumably overlapped for some extents.
Genetics
A 2017 study which attributed Late Pleistocene European remains to B. schoetensacki found it to belong to a mitochondrial clade which is the sister group to modern wisent, and proposed the species as a whole is likely ancestral to modern wisent. However, other studies have disputed this attribution, restricting B. schoetensacki to Early and Middle Pleistocene remains.
