500 million years ago, no creature had bones. Over time, those plates evolved into the structural wonders that vertebrates have today.
In fact, the skulls are very complex, and when viewed, they appear to be from fabulous and distant creatures. And only with that they already serve us so that on the internet there is the inspiration for good memes.
This time, people imagine how aliens would rebuild a creature if the skulls of … cats, dogs, etc. were found. Below you can see the fun results, but we warn you: a cat can be a tyrannosaurus in disguise.

Ashley Mason-Burns-Meerschaert directs the educational section of the Museum of Osteology, and she has told us more about the bones.
Vertebrate fish have the most bones in their skulls, more than 100. Although they may resemble those of different species, there are differences. Some species of shrews and rodents can only be distinguished by dental variations under a microscope.
There may also be sexual dimorphism, with the skulls of males and females of the same species being different.
Bones change due to adaptation to the environment, diet, or due to injury.
Details like huge eye beads indicate that the animal is nocturnal. Large canine teeth indicate that the animal is carnivorous. And lightweight bones with room for air are adapted for flying animals.
A human skull has 22 bones: 8 cranial and 14 facial. When a baby is born, the frontal bone is split into 2, but fuses as it grows.
But an alligator, for example, has 53 bones in the skull, and it’s not the one with the most.
