Leptictis is an extinct genus of non-placental eutherian mammal known from the Late Eocene to Early Oligocene of North America.^[1] The type species, L. haydeni, was named in 1868 by Joseph Leidy in honour of Ferdinand Vandeveer Hayden. L. dakotensis was also named by Leidy in 1868, but he originally named it as a separate species, Ictops, which is now seen as the same animal as Lepticitis. Since then, six other species have been named.^[2]^[3]
