Xenosmilus hodsonae (from Greek, ξένος, xenos, "strange" + σμίλη, smilē, "chisel" ) is an extinct member of the Machairodontinae, or saber-toothed cats. Two fairly intact specimens were found by amateur fossil hunters in 1983 (1981 by some sources) in the Haile limestone mines in Alachua County, Florida. In 1994 the fossils were examined, and it was decided that the cats were of an entirely new genus. The fossils were of Irvingtonian age (1.8 to 0.3 Ma).
