Ambulocetus, a bizarre beast. He is a predator.
— Allen, describing Ambulocetus

Ambulocetus (name meaning "Walking Whale") is a genus of cetacean (a bizarre, prehistoric whale-like beast with crocodile-like traits) that originated during the Early Eocene period.


Era & DiscoveryEdit

Ambulocetus lived in the Seas and Lakes of the Early Eocene period over 50 million years ago. Ambulocetus was recovered from the Kuldana Formation of Punjab, Pakistan in 1993 by Johannes G.M.

Physical AttributesEdit

Ambulocetus was a 10 foot (3 m) long carnivore that waddle awkwardly on land, however, in the water, they are faster and more agile. Although their ancestors hunted on land, Ambulocetus evolved to be far more at home in the water. In fact, their descendants took this aquatic lifestyle to an even greater extreme.

Although Ambulocetus may look like a kind of mammalian crocodile, they were actually the ancestor of the whales. In fact, their overall body shape itself is the very earliest form of whales. Hence their name, "Ambulocetus", literately means "Walking Whale".

Their styles of swimming had the appearance of dolphins and whales – when they swam, their bodies moved up and down as opposed to side to side like the fishes or crocodiles they shared their waters with.

Behavior & TraitsEdit

Living in anything from large ponds to even shallow seas, Ambulocetus were arguably the most powerful predators in their entire ecosystem. Much like crocodiles, they often prepared ambushes near the shores of lakes, rivers, and ocean coasts.

Despite the fact that these creatures didn't possess ears, Ambulocetus listened for incoming prey by placing their jaws directly on the ground and detecting vibrations. It was the same mechanism that allowed them to hear underwater as well. Their killing techniques were simple, similar to a crocodiles: their vise-like jaws held the struggling prey until it drowned.

Journal Entry Edit

Ambulocetus is a strange looking whale-like beast with crocodile-like attributes. However, despite looking like a crocodile, Ambulocetus's overall physical appearance is the earliest known form of whales, as its name literately means "Walking Whale".

And like crocodiles, Ambulocetus was an ambush predator; lying in wait close to the shore. And once its prey got close, it grabbed them and dragged them down to the depths. Ambulocetus could live in rivers, ponds, lakes, and even coastal shorelines.
