Before any animals are shown, it is important to know that the same fossil can reconstructed into something totally different.
To prove this point, let's take a look at a Confuciusornis.
Study these two images:
These depictions of the same bird are quite different, aren't they? One looks beautifully designed while the other looks ugly and perhaps a work of evolution. (Not meaning that all animals today seem beautiful)
Thus, we can say extinct animals can be portrayed to look however we want them to look based on our beliefs.
So, we must not be deceived by such pics.
