If you stood in the riverside forests that bordered the seasonal streams draining from the arid interior of the Triassic super continent , you would probably be surrounded by colourful little flying animals. These would have resembled butterflies or little birds. HAowever, neither of these existed at that time. Theseflying creatures would have been gliding diapsid reptiles. walking dinosaur costume
This animal, with its long scales along the back，may have represented an early attempt at flight. Sharov, the discoverer, suggested that spread sideways these structures could have formed an elementary gliding wing. Another interpretation, by Robert Bakker, is that they were brightly colouredand used for display orlu-at regulation. I hey may haveperformed all these functions. Fine striations on thesurface of the scales, and their central vein, suggest thestructure of a feather. This has led to the suggestion thatLongisquama lies on the evolutionary line that led tobirds, but few scientists accept this idea.
Features: The most remarkable feature of this little lizard-like animal is the double row of long scale like structures that run along the back, forming six to eight pairs. There is one pair for each pair of ribs on the body. They have a central hollow vane, like the feathers of a bird, but unlike feathers they appear to be formed of flat sheets rather than plumes. Only the front part of the body is preserved in the only known specimen and so the hindquarters here are conjectural.
