Bisonalveus is an extinct
Bisonalveus is represented by two known species: B. browni (Gazin, 1956) and B. holtzmani (Gingerich, 1983).[2][4][6]
Bisonalveus browni
Bisonalveus browni was discovered in 1956 from fossilized jaw fragments (including molars). Later discovered fossils included front teeth and a dagger-like canine tooth with an enameled groove.
Bisonalveus holtzmani
Bisonalveus holtzmani is named for Dr. Richard Holtzman, who, in 1978, described the first tooth that was later determined to belong to this species. B. holtzmani can be distinguished from B. browni in that it is about 30% larger.[2]
