During the Carboniferous to middle Triassic periods, approximately 120 million years ago, terrestrial life was dominated by a unique group of animals. These included pelycosaurs, archosaurs, and therapsids, which were often referred to as "mammal-like reptiles."

The pelycosaurs were a group of early tetrapods that resembled mammals in some ways, such as their warm-bloodedness and ability to nurse their young. However, they also possessed reptilian characteristics, like scales and egg-laying reproduction.

The archosaurs, on the other hand, were a larger and more diverse group that included both crocodilians and dinosaurs. They were characterized by a range of adaptations that allowed them to thrive in a variety of environments, from aquatic to terrestrial.

The therapsids, often considered the direct ancestors of mammals, were another important group during this period. They possessed a number of mammal-like features, including hair-like covering, warm-bloodedness, and three ear bones. However, they also retained some reptilian traits, such as egg-laying reproduction.
