Derivatives
pectinate
- Many species have thickly feathered legs; their well-developed talons have a smooth edge on the claw of the third toe (in contrast to the pectinate claw of the tytonids), which is longer than the second toe.
- The most striking difference is the elimination of the postcranially primitive clade of hominoids in the early Miocene in favor of a pectinate succession of taxa.
- They have long legs, and their inner toe, which is as long as the middle one, has a pectinate claw.
pectinated
- It differs in having ribs that are not as deeply pectinated and in having ribs that increase in number proximally by insertion rather than by bifurcation.
