Lemurs, living in the eastern region of Madagascar, are mammals with the ability to echolocate. Madagascar in Africa is the last sanctuary for lemurs, a primate with beautiful big eyes that has disappeared from the rest of the planet except this island.

Introduction

Lemur

8 genera of Lemuridea 26 species. This is the most primitive primate. The skull and nasal bones are elongated and shaped like a fox. Tooth type: 0~2/2, 1/1, 3/3. 3/3=32~36, the upper incisors are small or absent, there is a wide void between the incisors on both sides; the lower canines are cut, the first The lower premolars are canine-shaped and the molars are basically tricuspids. The sagittal ridge at the origin of the temporalis muscle is inconspicuous. The thumb and the big toe are somewhat enlarged, and are opposite to the other fingers and toes, and the second toe has a hook. The tail is long and hairy. Diverse diets, diurnal or nocturnal, are sensitive climbers.

Lemurs have a longer history and more species than previously thought. Ancient primates: Fossils of the 35-million-year-old primate Wadilemur elegans suggest that lemurs originated much earlier than old fossil evidence suggests. Lemurs are small primates endemic to Madagascar. A new fossil discovered by scientists in Egypt suggests that lemurs and other primates appeared much earlier in evolutionary history than previously thought; in addition, scientists have discovered five new lemur species.
