Euparaves (2)

This is a cladogram from an earlier post.
It shows the placement of Euparaves, but the cladogram is still not completely correct since Euparaves is not actually connected to dinosaurs.

Euparaves (node-based) definition:
"The most recent common ancestor of Epidendrosaurus ninchengensis (Scansoriopterygidae) and Passer domesticus (the house sparrow), and all descendants thereof".

Here is the stem-based definition of Euparaves:
"The most inclusive clade containing Passer domesticus (Linnaeus 1758) but not Pterorhynchus wellnhoferi."

Here are the apomorphies of Euparaves:
possessed remiges and rectrices, that is, enlarged, stiff-shafted, closed-vaned (= barbules bearing hooked distal pennulae), pennaceous feathers arising from the distal forelimbs and tail
possessed feathered wings used in flapping flight

Concerning flapping flight, also see:
