A new set of fossil trackways from South Korea shows surprisingly long spacing between between steps made by a small microraptorine (ichnotaxon Dromaeosauriformipes). Relative to body size, the strides were three times as long as that of an ostrich and nearly twice as long as that of a kangaroo rat.
Basically, the microraptorine was using its wings to get some air time when running at high speeds, and also to help with braking and turning.

For those who don't know, Dong Zhiming discovered and described more than 42 genera of dinosaurs, mostly from the Middle Jurassic aged Shaximiao Formation. These include Tuojiangosaurus, Micropachycephalosaurus, Shunosaurus, Wuerhosaurus, and Archaeoceratops.
About the Saurophaganax sauropod thing, stay tuned.
