Fifteen tracks (footprints) of theropod dinosaurs, preserved as convex hyporelieves on a large splitted fine gravel-bearing coarse sandstone (a creeping rubble) have been discovered from the Early Cretaceous Longwangzhuang Formation, Laiyang Group in the Laiyang basin, China. Of the fifteen footprints, only one is poorly preserved. Our research shows that all the tracks are possibly left by a single theropod dinosaur, probably of the coelurosaurs. A new ichnogenus Pra-grallator ichnog. nov. is erected. It is predicted that the track-maker lived in a coastal lacustrine-fluvial environment.
