Why did the Pakicetus not survive?

What did Pakicetus use its tail for?
The large tail of Pakicetus is possibly a specialization for aquatic locomotion, although exactly how is unclear. Such muscles are consistent with webbed feet that were used for aquatic locomotion. Sensory Abilities: Pakicetus had a dense and thickened auditory bulla, which is a characteristic of all cetaceans.
What features did the Pakicetus have?
Pakicetus had a long snout; a typical complement of teeth that included incisors, canines, premolars, and molars; a distinct and flexible neck; and a very long and robust tail. As in most land mammals, the nose was at the tip of the snout.
Which land animal is the closest cousin to dolphins?

Did Dolphins evolve from wolves?
The early dolphins were smaller and believed to have consumed small fish as well as various organisms in the water. The older theory is that the evolution was of whales, and they came from ancestors of hoofed land animals that were very similar to wolves and even-toed ungulates.
How did Pakicetus look like before becoming whale?
What did the first whales look like? Pakicetus (pictured above) looked nothing like a whale, but it would have felt at home in the water. It lived on land, on the edge of lakes and riverbanks in what is now Pakistan and India. It hunted small land animals and freshwater fish, and could even hear underwater.
