ONLY just hatched and new to the world, the little guy who left these 
prints in the riverbed was probably running for its life. Barely 10 
centimetres tall, the hatchling would have been the length of a wren and 
easy prey for pterosaurs and other hungry dinosaurs.

The prints are the tiniest dinosaur footprints ever found. They were left 
between 125 and 110 million years ago, are just 1.27 cm and 1.51 cm long, 
and clearly show soft foot pads and three pointed claws.

Kyung Soo Kim of Chinju National University of Education in Jinju, South 
Korea, says the baby track-maker was a cousin of the fearsome T. Rex and 
belonged to the theropod sub-order, which includes tyrannosaurs.

"It was running to hide right after hatching," Kim speculates. It had 
plenty of reasons to do so: nearby tracks show it shared its home with 
fleet-footed, meat-eating dromeosaurs, such as Velociraptor, together with 
other dinosaurs, pterosaurs and shorebirds.
