Paleontologists in Spain have canvas two set of fossilized dinosaur footprints and calculated the animals ’ speed at the times the prints were made . The team found the dinosaurs that made the prints could move at near 28 miles per hour , a swiftness that be that of the world ’s fast humans .
Of course , humans like Usain Bolt can only achieve such pep pill briefly ; the dinosaur that produced the tracks would have sprinted longer distances . bird-footed dinosaur — generally carnivorous , bipedal dinosaur like T. king and velociraptor — would have needed to move quickly so as to beguile their prey . The team ’s research on the fossilized footprints waspublishedin Scientific Reports .
Dinosaur biomechanics tells paleontologists a hatful about the ecology of the ancient past times and the phylogenesis of species . “ Behavior is something very unmanageable to learn indinosaurs , ” lead author Pablo Navarro - Lorbés , a paleontologist at the University of La Rioja , told the AP . “ These kind of findings are very important , I think , for better that kind of cognition . ”

In September , a unlike squad find that bipedal dinosaur like those that made the of late study cartroad in all probability used their tush to balance as they changed their impulse , a trait that some hoot ( modern dinosaurs ) still display today .
The tracks were found in northern Spain , at a internet site called La Rioja . They were preserved in two trackways , one contain six step and the other comprising seven . All the footprint are three - toed and about a invertebrate foot long .
The squad calculated the animals ’ speeding by appraise the spacing between the footprints and estimate the animals ’ hip elevation . ( The investigator conceive the track - makers were around 6 to 6.5 groundwork tall and 13 feet to 16 feet nose to tail . ) The average stride length of these trackways was 265 centimeters , or about 8.7 foundation . Usain Bolt ’s average stride duration is247 centimetre , or about 8.1 feet .

The team compare the recent trackways and the calculated speeds of the dinosaur that made them to other know theropod trackways , to get an idea of what kind of animal may have made them . Though the paleontologists were not able to announce a specific species , they stated in the paper that the footprints indicated a “ medium - sized , non - avian theropod . ”
The track - makers in what is now Spain were among the fast - yet - known dinosaur . But they did n’t quite clench top smudge ; that purity goes to a grouping of dinosaurs thatleft prints in what is now Utah . Those creature were journey at over 30 miles per time of day when they left the mark .
