And of course I wouldn't like to be caught by this guy on a riverbank," said Pablo Navarro-Lorbes, a paleontology doctoral student at Universidad de La Rioja in Spain and lead author of the research published in the journal Scientific Reports.
Running speed was calculated based on the relationship between the animal's hip height - estimated from the footprint length - and stride length. The stride length from one of the trackways was 18.3 feet , while the other was 17.2 feet .
