Incredible discovery: These raptors ran very fast thanks to their winged arms!

A new study shows us the extent to which feathers, and particularly wings, may have represented an evolutionary advantage in some dinosaurs, and not just for flight. The discovery of footprints suggests that some dinosaurs used their wings for bursts of speed when running.

If the first birds appeared only 150 million years ago, abundant fossil evidence suggests that dinosaurs had feathers on their backs long before that date. It was actually towards the end of the Triassic, 200 million years ago, that they appeared. For a long time, they were used for something other than gliding or flying, especially as protection from the cold or as a reproductive display device. But wings can also be very useful when running, as revealed in this new study published in the journal. Pinas.

A race with fluttering wings

A team of researchers has actually discovered a trail of fossilized footprints in South Korea that suggests that DinosaurDinosaur Used his arms to run faster. This is the earliest evidence of “wing-assisted running”.

The dinosaur in question, Dromaeosauriformes are rarewas a Raptor no. They wereThey werethat is, not part of the first bird lineage. However, it has been proven that it had feathers and wings, although they were too small to allow flight. However, they may have provided our little dinosaurs with a significant advantage 120 million years ago.

A true sprinter

For the researchers, there’s no doubt about it: the small dinosaurs used their wings to extend themselves considerably, as some birds do when they fly. with your wings, Dromaeosauriformes are rare Thus could get a vitessevitesse 37 km per hour!

These accelerations are likely to have been very useful for him in hunting or escaping predators himself.
