Could Titanoboa or Vasuki indicus have been the real animals behind ancient Chinese dragon myths?

Okay, this is obviously wild speculation, but I came across Titanoboa and Vasuki indicus and started wondering about something.

What if ancient "dragons" weren't originally completely fictional?

Titanoboa was a gigantic prehistoric snake that may have reached around 13–15 meters (42–49 ft), while Vasuki indicus, discovered in India, may also have reached roughly 11–15 meters. Neither is known from a complete skeleton, so there's still a lot we don't know about exactly what these animals looked like.

Now imagine an alternate scenario:

What if a Titanoboa/Vasuki-like lineage survived much later than we currently know, evolved some kind of limbs or other adaptations, and—under completely hypothetical changes to its biology/physics—even became capable of flying or gliding?

Imagine an enormous, long-bodied reptile flying through the sky.

Ancient humans wouldn't have had modern zoology or paleontology to explain what they were seeing. If someone in ancient China saw a gigantic serpentine creature flying through the sky, they might describe it as something supernatural.

Over generations, those sightings could become stories, artwork, religious symbolism, and eventually what we recognize as the Chinese dragon (龙).

And interestingly, Chinese dragons are traditionally depicted as extremely long, serpentine creatures rather than the four-legged, winged European-style dragon.

I'm NOT saying this actually happened. There's currently no evidence that Titanoboa or Vasuki survived into historical times, lived in China, or could fly.

I'm just wondering:

If a giant prehistoric snake-like animal really had survived into ancient human history—and possessed some completely unknown biological mechanism that allowed it to fly—could encounters with it have contributed to the development of dragon mythology?

Basically:

real prehistoric animal → ancient human sightings → oral stories → mythology → Chinese dragon

It's probably impossible to prove, but I think it's a fun thought experiment.

What do you guys think?
