Imagocnus  Imagocnus is an extinct genus of ground sloth from the Early Miocene (Burdigalian) Lagunitas Formation of Cuba. This sloth resided in the Antilles and showed a range of body size, from "Parocnus"-sized to "Megalocnus"-sized or larger. Its relationships to other Antillean sloths are not immediately clear, though the genera "Megalocnus" and "Parocnus", other ground sloths, are its most likely relatives.
