When did dolphins evolve?

Answer:

Dolphins evolved from whales, and both of them evolved from ungulates, hoofed animals, that ate meat and took to the water. Early whales, like Himalayacetus subathuensis, lived on land but possibly lived like crocodiles.

Answer:

Dolphins and Whales are related to each other, so that means that Dolphins evolve from a Dinosaur named Ichthysaurus.

Answer:

According to the National History Museum, London, dolphins have an ancestor in four-legged mammals similar to wolves. They used to have claw like hands which caught fish they gradually became more fin like and that is how they evolved into dolphins.

Answer 2

Dolphins evolved from whales and they evolved from something called a Mesonix. They ate in they water, and from then on, over 30 million years, they evolved the means to better be suited to the water. The closest living land cousin to the dolphin according to Japanese Genome study, is the pig and other augulates, (hoofed animals) Anyways, so from the Mesonix back, I'm assuming it had to have evolved like most of the other mammals did from dinosaurs, through birds, and what not. That I'm not sure but I DO know what the dolphin's land form was now cause I got stupid curious.
