The restricted, unbalanced nature of the Caribbean mammal fauna implies that rafting was part of the overall process. This is consistent with the fact that megalonychid sloths, platyrrhine monkeys and caviomorph rodents have all shown a capacity for this type of dispersal (in their colonization of North America from South America
