text_A: "Dsungaripterus weii" had a wing span of 3 to 3.5 meters (9.8 to 11.5 ;ft). Like most dsungaripteroids it had a rather robust skeleton with thick walls and stouty bodily proportions, suggesting a mostly terrestrial lifestyle. The flight style of these animals is well researched and certainly included extensive flapping, but it's unclear if it was punctuated by abrupt landings.
text_B: Would "graceful" be an accurate word to describe the way the Dsungaripterus weii probably flew and landed?
NO.
