One of the Triassic's most bizarre animals, the Cynodont is a missing link between reptiles and mammals.
— Allen, describing Cynodont

Cynodont is a genus of mammal-like reptiles that lived during the early Triassic period in what is now South Africa and Antarctica.



Cynodont lived during the Triassic Period, 258-220 million years ago. It was constantly bothered by dinosaurs like Coelophysis.


One of the Triassic's most bizarre animals, the Cynodonts were a missing link between reptile and mammals. As they ran, their back-bone moved from side to side like a reptiles but they had hair and lived down a burrow like a mammal. Females often slept on a bed of lichen.


The bond between Cynodonts was extraordinarily strong, they paired for life. Like all land reptile, they laid eggs but after hatching, the young were utterly dependent on their parents and spent their first three months feeding from special milk glands on the mother’s stomach. This form of reproduction had evolved to protect their young from the daylight predators outside their burrows. By day, even the fathers stuck close to the safety of the burrow and carried out domestic chores. The males only hunted at night and possibly their most common prey were baby dinosaurs.

Journal EntryEdit

Cynodonts are bizarre, Triassic creatures that are the missing link between reptilian animals and mammalian lifeforms. When running, their back bones move from one side to the other, like a lizard. But because that of their mammal-like appearance as well, they have fur and live down burrows like mammals.

As it turns out, they pair for life. As another part of their reptile-mammal-hybrid nature, the females lay eggs, but when they are born, the young feed off of their mothers milk. The males only hunt at night whereas the females stay in the burrows and sleep on a bed of lichen.
