No organism had bones 500 million years ago. Those plates evolved over time into the structural marvels that vertebrates possess today.
The skulls are in fact extremely complicated, and when inspected, they look to be from fantastic and faraway creatures. And only with that do they already assist us by providing inspiration for nice memes on the internet.
This time, people are imagining how aliens would reconstruct a creature if the skulls of… cats, dogs, and other animals were discovered. The fun results are below, but be warned: a cat can be a tyrannosaurus in disguise.

The teaching area of the Museum of Osteology is directed by Ashley Mason-Burns-Meerschaert, who has taught us more about the bones.
The cranium of vertebrate fish have the most bones, with over 100. There are differences amongst them, even though they look similar to those of other species. Under a microscope, certain shrew and rodent species can only be recognised by dental differences.
There is also the possibility of sexual dimorphism, with males and females of the same species having differing skulls.
Bones alter as a result of environmental adaptability, diet, or injury.
The animal is nocturnal, as evidenced by the large eye beads. Carnivory is indicated by the presence of large canine teeth. Flying creatures require light bones with plenty of area for air.
There are 22 bones in the human skull: eight cranial and fourteen facial. The frontal bone is divided in two when a newborn is born, but it unites as the child grows.
However, an alligator’s skull has 53 bones, and it is not the one with the most.
