RE: Terrestriality is a bias




>>All the references I've checked indicate that the Aye Aye's elongated
digit
is an adaptation for feeding (reaching into holes in trees to extract
larvae) not for arborealty. It is unique among all arboreal lemurs in having
that modification.  If that's the case, how does your analogy support
arborealty in this new little dinosaur?<<

Luis should have added this, the retrevered helix is just as low on the
metatarsals as modern birds. This means that it could have easily perched
while using its long third digit (?).
