supports: An anapsid is an amniote whose skull does not have openings near the temples. Traditionally, the Anapsida are the most primitive subclass of reptiles, the ancestral stock from which Synapsida and Diapsida evolved, making anapsids paraphyletic. It is however doubtful that all anapsids lack temporal fenestra as a primitive trait, and that all the groups traditionally seen as anapsids truly lacked fenestra. Arganaceras ( `` Argana horn '' ) is an medium size pareiasaur from the Late Permian of Morocco . It was about 2 m in length and had a horn - like structure on its snout . It was closely related to the European genus Elginia . The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World". The Maghreb (or ; literally "sunset"; ', "the Arab West" previously known as Barbary Coast, derived from Berber), or the Greater Maghreb ("al-Maghrib al-Kabr"), is usually defined as much or most of the region of western North Africa or Northwest Africa, west of Egypt. The traditional definition as the region including the Atlas Mountains and the coastal plains of Morocco, Algeria, Tunisia, and Libya, was later superseded, especially following the 1989 formation of the Arab Maghreb Union (  ), by the inclusion of Mauritania and of the disputed territory of Western Sahara (mostly controlled by Morocco). During the Al-Andalus era in Spain (7111492), the Maghreb's inhabitants, Maghrebis, were known as "Moors"; the Muslim areas of Spain in those times were usually included in contemporary definitions of the Maghrebhence the use of "Moorish" or "Moors" to describe the Muslim inhabitants of Spain in Western sources. Elginia was a pareiasaur; a member of a group of Late Permian parareptiles which may have grown up to . Morocco (', lit. "The West"; '), officially known as the Kingdom of Morocco (', lit. "The Western Kingdom"; '), is a sovereign country located in the Maghreb region of North Africa. Geographically, Morocco is characterized by a rugged mountainous interior, large tracts of desert, and a lengthy coastline along the Atlantic Ocean and Mediterranean Sea. The Permian is a geologic period and system which spans 46.7 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 252.2 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the city of Perm. Pareiasaurs (meaning "cheek lizards") are an extinct group of anapsid reptiles classified in the family Pareiasauridae. They were large herbivores that flourished during the Permian period.
