From Deviant Art (h/t: Matthew Cobb again), we have this lovely picture of dromaeosaurs, drawn to scale with a dapper human (Fred Astaire?) to the right.
Dromaeosaurs are small bipedal theropod dinosaurs that lived during the Cretaceous. At least two species may have flown or glided (these include the famous “four-winged” Microraptor gui, #1 and sitting on Fred’s hand), and many were covered with feathers. They aren’t considered the ancestors of birds, or even in the same group of theropods that gave rise to birds, but are currently regarded as a sister group—closely related to the group that was ancestral to modern birds.
Now the colors are completely speculative, and the feather arrangements best regarded as “informed speculation,” but they probably looked pretty much like this (click to enlarge). One doesn’t usually think of these “raptors” as cute, but they seem so with colors and fuzz!
Microraptor gui, fossil. Note the feathers on all four appendages (I’ve added arrows to show them on front- and hindlimbs):
