Smilodon fatalis was widespread, having been found coast to coast in North America, as far north as Idaho and Nebraska and southward into South America. It is best known from California and Florida. The geologically oldest record of Smilodon is about 500,000 years old and the youngest is only 9,400 years old, an animal found during the construction of a bank in Nashville, Tennessee.
In Indiana, Smilodon has been found at the Harrodsburg Crevice site in Monroe County, just south of Bloomington, in sediments filling a sinkhole. Dire wolves, extinct peccaries, and assorted other mammals were found at the same site. The age of the Harrodsburg Crevice fauna is somewhat uncertain because it appears to be older than can be dated with radiocarbon, but the animals there most likely lived during the last interglacial period about 140,000 years ago.
The Dire wolf is well known in Indiana: the first fossil remains were recovered in 1854 from the Ohio River terraces near Evansville by Francis Lincke. The species was later described by Joseph Leidy of the Philadelphia Academy of Sciences based on Lincke's Indiana fossils. At least three sites in Indiana have produced specimens of Canis dirus--the Evansville site and ones in Monroe and Crawford Counties - and it is known from all the surrounding states except Michigan.
