Eozostrodon is an extinct Morganucodont mammaliform. It lived during the Rhaetian stage of the late Triassic into the early Jurassic. Eozostrodon is known from disarticulated bones in Wales and Southwest England and estimated to have been less than 10 cm (3.9 in) in head-body length, slightly smaller than the similar-proportioned Megazostrodon. Its teeth were typically mammalian, being differentiated into molars and premolars with triangular cusps.
