Living during the Triassic, Longisquama was a small, lizard like creature that appears to have had a series of long feathers on its back. This implies that birds might have not evolved from theropods, but lizard-like reptiles instead. Of course, things are not always what they seem. Some scientists think they are just specially modified scales. Others think that the fossil’s form is an optical illusion: that the feathers are just fern fronds. Due to the large amount of feathered dinosaur fossils, it seems that these two possibilities are more accurate.
