mammary glands
True fur is a feature unique to mammals, which are entirely separate from dinosaurs. Rather there is mounting evidence that many dinosaurs actually had feathers.

The unique traits that helped mammals survive are called adaptations. Some of their adaptations include their hair, mammary glands, and three specialized middle-ear bones.
Mammals (class Mammalia) are group of vertebrate animals in which the young are nourished with milk from special mammary glands of the mother. In addition to these characteristic milk glands, mammals are distinguished by several other unique features. Hair is a typical feature, although in many whales it has disappeared except in the fetal stage. This ability to feed the offspring with milk occurs in whales as well.
All mammals feed their young with milk, have hair, have a neocortex region of the brain, and have three middle ear bones. There are other characteristics shared by all mammals, but the above four are (for the most part) that only ones unique to mammals.

Dens are unique to the axis.
Aristides identified Christianity as the unique feature of the Roman Empire.
Mammals have hair and they give milk to their babies.
Mammals have internal breeding and have sexual intercourse in order to fertalize the eggs. Other animals have external breeding where the female lays the eggs and then the male fertilizes it. In simpler terms, Mammals have sex, and other animals don't.
A unique feature is that it has many tall towers with curving sides that taper at the top.

Great white sharks are fish not mammals. Mammals are unique in that they have body hair, have three middle ear bones (the incus, malleus, and stapes), and nourish their young with milk from the female mammary glands. The great white shark has none of the above characteristics.
Mammals have a number of characteristics that make them mammals. Firstly, they are chordate animals possessing vertebrae. But that take us down to all vertebrates; beyond that the mammalian features are 1. Females have mammary glands 2. Unique Sweat Glands (only mammals have) 3. Presence of Hair and/or Fur 4. Three middle ear bones 5. Presence of Neocortex in brain
All mammals expend a significant amount of energy producing milk for their offspring. This is an evolutionary feature unique to mammals and it confers a significant benefit to the offspring - the milk is complete nutrition for the offspring, which gives the offspring better odds of surviving to reproductive age itself.
