Did dinosaurs fly?

This story us back 129 million  years ago when a dinosaurs had wings flight that it may have taken flight. But the  proof is Darwinian storytelling, that cannot be held as true.

Tiny tracks in South Korea symbolise a moment 120 million years ago when a dinosaur took advantage of its wings to cover ground in large leaps – the oldest track evidence of wing-assisted movement in these extinct animals.

Whether the creature, which was a raptor and not part of the lineage that led to birds, took full flight is uncertain. But the tracks support previous ideas that aerodynamics evolved multiple times across prehistoric lines, says Alexander Dececchi at Dakota State University in South Dakota.

“It’s pretty rare to find these kinds of [pre-flight] tracks, and then to find them in an animal that’s not even a bird – that’s pretty special,” he says.

Velociraptors and other raptors (dromaeosaurids) are the ancestors of modern birds, but their lineage split into avian and non-avian, or “paravian”, lines about 170 million years ago. Despite having feathers and wings, paravian dinosaurs generally seemed to lack the wingspan needed to offset their body weight, says team member Michael Pittman at the Chinese University of Hong Kong.

But Pittman, Dececchi and their colleagues suspected that some paravian dinosaurs could fly, or at least glide, before full flight evolved in birds, based on muscles in their upper bodies. That suspicion grew stronger as they investigated more than 2600 rows of dinosaur tracks around the world.

Yes, evolutionists are still uncertain if the animals flew.
