Characteristics of  Prehistoric Whales

Prehistoric whales belong to the family  of the cetacean mammals, which means they are ancestors of whales. They lived during  the  Cenozoic Age millions years ago, which doesn´t  mean that they have lived at the same time than dinosaurs, but there is no doubt that they were  the first forerunners of whales.

After watching the first  image, you could think that they aren´t  similar to the current whales;  but as we mentioned previously they are the forerunners of whales.

They  lived more than 40 million years, in the late Eocene. Many people tend to ask about the remains of the Basilosaurus;  which  have been found in  different  geographic  locations, since they were marine animals.

What makes these creatures a little different from whales, is that  they had several mutations, beginning  from their  relatives; until   what we nowadays know as their  large descendents , which are the animals that today  live in the ocean.

The shape of the jaw, is One of the most outstanding differences between the prehistoric whales and the current ones; since it does not usually resemble what is the image of the whales today. The prehistoric had much more than three Dozens of dental elements, which could easily  cut anything  they needed. (see article : pygmy whale)

On the other hand, the rear teeth had a peculiar shape of triangle, which led the scientists to the conclusion;  that they served to devour their prey without mercy. That means that the teeth were vital to capture victims, which were their main food.

It is important to point out, that the  Basilosaurus or Prehistoric whales had rear legs of approximately  65 centimeters; which is an intriguing fact . As for their  head, it he didn´t  have as much space as the whales of today, which means that their brain was much smaller;  and they probably   didn´t  have the skills that whales have today.

As far as the length of  Basilosaurus, it was around 20 meters, which means they were really large. These creatures could only swim and displace in the shallower waters of the oceans, which makes the big difference with the current whales; which  have the ability to submerge for a long time.

The Basilosaurus or prehistoric whale was the largest whale of its age; which is to say that it was also the largest animal on the Earth.

They were lonely creatures, which only gathered  with those of the same specie; mainly for mating purposes at the time that a mother was taking care of her offspring. Their breathing method was quite similar to that of the current whales, since they had to come to the surface periodically; to be able to take air. However  since they didn´t have spiracles, like those of the current whales; they had to get their entire head, outside the water to be able to breathe deeply through their nose. (see article how do whales breathe 

As you should have noticed throughout the article, the Basilosaurus or prehistoric whale has many similarities with the current whales. Thus it is always good and necessary to know about history, and especially to learn something new every day
