in size to a gorilla, Archaeoindris is one of the
largest known sloth
lemurs. Initially considered to have been a ground dwelling
quadruped, further study has now led to the suggestions that
Archaeoindris could have still climbed branches
(albeit the thicker
ones that could support its weight) as it foraged for food. This is
where the sloth comparison comes from, as rather than being fast and
agile like the more lightly built indriid lemurs we know today,
Archaeoindris would have probably been slower and
more sluggish to
reduce energy expenditure as it foraged.
Other genera of sloth lemur include Babakotia, Mesopropithecus and Palaeopropithecus.
