Despite their looks, Dinnos are more closely related to the Salaslyke than any of the dragons found on Ark. Dinnos are often called the "False Dragon." The scales on their skin are soft and not like what most people think of when they think of scales. Even what is believed to be a growing remnant of the creature's egg is actually a specialized armor created by hard scales. As Dinnos age, the armor shrinks in comparison to body size. Those who have grown out of their shells are seen as the oldest and most wise of them all.
Dinnos are actually quite playful and artistic. During the breeding season, males make natural paints and decorate their bodies using their claws, tails, and even noses to impress females. If a female takes an interest, she steps into some of these colorful supplies, rolls onto her back, and imprints her foot on the male's shell.
In captivity, Dinno owners keep their pets happy by providing them with art supplies. Some are even dexterous enough to manage to use brushes. Since a law bans formal ownership, a new trend has been growing in popularity in the art community: "Dinnos on Canvas."
