Oh.

So, what is the basic thing you guys, are discussing, just out of curiousity. I ask because i could potentially add my thoughts in.

I understand that just because one individual genus has a trait (quills on a ceratopsian for instance) doesn't mean it applies to the whole family but what are the chances that other Scansoriopterygidae aside from Yi qi had a "wing" membrane?

I don't think it would be impossible to think that this trait was confined to just Yi Qi perhaps there could have been multiple forms that occupied different habitats.

i think it's reasonable to think Yi isn't the only scansoriopterid with a membrane.
if other scansoriopterids had not a membrane like the one Yi possessed perhaps the membrane resembled that of a chicken's wing membrane.

kind of a speculative question, but could dromaeosaurs have had feathers protruding from their first finger digits in a similar manner to a kestrel's alula/bastard wing?

Doubt that... Alula feathers have function for flight in many kinds of bird and some birds don't even have them, so I don't know if it would have any role for the flightless Dromaeosaurs.

It could've aided in balance while restraining prey, but that's about the only advantage I can think of.

Unlikely.

The aula's function is that it redirects airflow over and under the wing to assist in braking and turning. The animal in question would need to be moving through the air at speed, with intent of changing speed or direction without stalling.

It doesnt do much when you are already on the ground.

Besides, in larger dromaeosaurs, thats what the wings and tail would be for.

Noting as well, as previously mentioned, its a trait unique to true birds, and not even all birds have them. So they likely would not have been present in dromaeosaurids anyway. And if they were, theyd get in the way of otherwise grasping thumbs.

It glided with them, AFAIK it wasn't a great flyer.
