This is certainly a possibility. My take is that all it would need to be
scansorial (at least) would be claws, especially manual claws, suitable for
clinging to a tree trunk.
[Also, I think the indri may the lemur that leaps sideways].

Pretty much always a close sister group to Dinosauria.
[Indeed, since the type of _Lagosuchus_ lacks apomorphies, _Lagosuchus_
could actually *be* a dinosaur ancestor].
