dwarfism in Mainland Species

Ok, I was going to ask this on another forum but i thought people here would be more knowledgeable on the subject.

Is it possible for say, a lion, tiger, bear, Or any animal that can be found on the mainland of a Continent and not on an island, to suffer from dwarfism Like humans?

I ask this because for one of my new Animasaurus Models, i plan on doing a Little people version of a triceratops, and i would like to know if that is possible without any human interference on any wild animal that is not the product of Island dwarfism.

Dwarfism is possible among every species, animals or plants. Mainland dwarfism is possible for a wildlife species but it is very very rare.

Look  

So a Dwarf Triceratops would be rare sight to see.

I got the idea after Tatankaceratops which many think is either juvenile, or a individual with a Growth disorder. Now i can only do Adult animals for the Line, so this would be an adult that suffered from dwarfaism
