"If the tracks were made by dinosaur chicks, we are unclear as to the specific dinosaur that made them, since dinosaurs such as Velociraptor and Utahraptor had larger feet then the ones discovered in these new tracks."

If the raptor is indeed a new species, it wouldn't be alone on the small end of the dinosaur scale. Other species like the Chinese microraptor also enjoyed a vantage just a few inches above the ground. The Chinese microraptor's feet were too big to account for the newly discovered tracks.

"We have named these small tracks Dromaeosauriformipes rarus, which means rare footprints made by a member of the raptor family known as dromaeosaurs," Kim said.

The Jinju Formation where the tracks were discovered are home to dozens of Cretaceous period footprints.

"In addition to tiny dinosaur tracks, we have footprints made by birds, pterosaurs, lizards, turtles, mammals, and even frogs," said Soo Kim, researcher at South Korea's Chinju National University of Education.
