The buffalo (aka American bison) was a large quadruped native to Earth. Although once, as late as the 19th century, they existed in vast, unnumbered multitudes on the prairies, the buffalo was aggressively hunted and had become extinct by the 23rd century.
In 2266, Professor Robert Crater compared the fate of the M-113 creature to that of the buffalo. (TOS: "The Man Trap")
After Jonathan Archer restored a damaged timeline, a herd of buffalo could be seen in the time stream as the timeline realigned itself. (ENT: "Storm Front, Part II")
