Alladontosaur [al-lah-don-toe-saur], often informally shortened to Alladon or simply Don, means "Different Toothed Lizard". They acquired this name after researchers noted the unusual placement of their canines compared to other modern day animals.

They are a hardy, fast adapting species and believed to be the last remaining member of the therapsida order.

There are three recognized breeds within the alladon genus, and all same practically the same biology (aside some rather striking physical differences). This document will cover the basis for all three unless specifically aimed at one breed in particular.

Alladon species has its own official website.
