Therapsids were a group of synapsids that adapted by developing vertically extended limbs in contrast to crawling, more symmetrical feet, more complex and powerful jaws, and frontal incisors and canines for tearing. Hadrocodium were primitive mammals with advanced features like a large brain and advanced ear. Prosimians are a group of primates characterized by primitive mammalian traits like a bicornuate uterus.
