Minisauripus is an ichnogenus of dinosaur footprint. Minisauripus is regarded as the smallest pre KT-extinction dinosaur ever discovered. It was less than 20 cm (7.8 inches) long. Its footprints have been found in the Jinju Formation and the Feitianshan Formation, a low-energy lake formation.
The lack of claws and scales suggest that these footprints were made by large amphibians, being often attributed to eryopid temnospondyls. [ 1 ] [ 2 ] [ 3 ] The lack of belly and tail marks in the sediment indicates that the producer raised most of its body when walking and had a short or non-dragging tail.
