This is the first description of dinosaur footprints from the Yixian Formation. The tracks were left by at least three individual track makers. It is estimated from the tracks that the body lengths of the track makers were 1. t1:chmetcnv w:st="on" UnitName="m" SourceValue="51" HasSpace="True" Negative="False" NumberType="1" TCSC="0">51 mt1:chmetcnv>. The feet of Caudipteryx and Sinosauropteryx were reconstructed. The former was more similar than the latter to the Grallator isp. track outlines. Feet capable of registering Grallator morphotype tracks may therefore have been widely distributed in small-medium sized theropods (other than dromaeosaurids and troodontids) from the Yixian Formation. t;urn:schemas-microsoft-com:office:office" />
