It's not a myth. It's not exactly correct to say they were 'dolphins' ... but the *ancestors* of modern dolphins and whales were indeed land animals (as they are mammals).
Dolphin embryos still have rear leg buds ... here's a photo:

... and adult dolphins and whales still have hip bones.

Yes... I found a page for you to read...here is the synopsis- it is much easier to read then the page
Dolphins are mammals, and as such, evolved from terrestrial creatures. On this page you can find answers to such questions as: How and why did they reenter an aquatic existance millions of years ago? When did the numerous adaptations that help them to survive in the water develop? What were the first cetaceans like?

Its no myth. Whales and dolphins evolved from land creatures. They still have the hips in their skeletons to prove it.

No, dolphins never "walked the planet" because they lack functional hindlimbs and their forelimbs are flippers.
However, the ancestors of dolphins were ungulate tetrapods, and they did.
Here are some of those ancestors:
