Hudson-Meng Bison Kill in northwestern Nebraska is a major archaeological and fossil site preserving a dense bonebed about 10,000 years old with remains of as many as 600 bison. Discovered in 1954 by Bill Hudson and Albert Meng, it was extensively excavated beginning in the 1970s. Once thought to be the largest Alberta Culture bison kill site ever found, later research concluded the animals died from unknown natural causes rather than hunting. The site also yielded evidence of both Alberta and Eden components and preserves a transitional bison form between Bison antiquus and modern Bison bison, making it important for understanding ancient Plains animals and human presence.
