Can someone gimme a list of taxa which have lost SLC?

Does it mean that they were able again, for example, to catch a prey with
ONE hand?
In order to make further drawings more accurate...

About art...
I found home among dirty old things an ooooooooooooold book about dinosaurs
and other prehistoric beasts I received when I was 8.
Most illustrations are now inaccurate (for dinosaurs), but they're... Z.
Burian's.
I can imagine his illustrations with the knowledge we have today...
