Phosphatherium
''Phosphatherium escuillei'' is a basal proboscidean that lived from the Late Paleocene to the early stages of the Ypresian age until the early Thanetian some 56 million years ago in North Africa. Research has suggested that ''Phosphatherium'' existed during the Eocene period. Description ''P. escuillei'' possessed rather flat features, centered around a low skull and a long, straight dorsal profile. The skull itself was rather disproportionate, consisting of an elongated cranial region and a rather short rostrum. The sagittal crest, the ridge along the dorsomedian line of its skull, spans across nearly half of the skull itself. The nasal cavity is high and wide, suggesting a large snout in life. One of the main factors of ''Phosphatherium'' body is its nontraditional musculoskeletal system. The shape of its head is composed of attributes of a snout, more vividly, turning into a mouth with a rounded jawline. Similar mammals in its order retained a more snout-like nose, wh ...

Numidotheriidae
Numidotheriidae is an extinct family of primitive proboscidean that lived from the late Paleocene to the early Oligocene periods of North Africa. Fragmentary fossils (mainly teeth) of the early Eocene genera, ''Daouitherium'' and ''Phosphatherium'', have been found in the Ouled Abdun Basin, Morocco. ''Numidotherium'' is known from an almost complete skeleton from late early Eocene deposits in southern Algeria and Libya. Compared to modern elephants, the Numidotheriidae were quite small. ''Phosphatherium'', for instance, was only 60 cm long and weighed about 15 kg. ''Numidotherium'' was about 1 m in length. They occupied a similar ecological niche to the modern hippopotamus and the related early proboscid ''Moeritherium ''Moeritherium'' ("the beast from Lake Moeris") is an extinct genus of primitive proboscideans.

Eritherium
''Eritherium'' is an extinct genus of early Proboscidea found in the Ouled Abdoun basin (early Thanetian age), Morocco. It lived about 60 million years ago. It was first named by Emmanuel Gheerbrant in 2009 and the type species is ''Eritherium azzouzorum''. ''Eritherium ''is the oldest, smallest and most primitive known elephant relative. Description The holotype (specimen number MNHN PM69) is now in the Musée d'histoire naturelle - Guimet in Lyon and includes an upper jaw (with approaches of the zygomatic bone and two maxillary branches, each of the two posterior premolars (P3 and 4) and three molars (M1-3)). The piece is about 6 inches long, 5 inches wide and just over 3 inches high. In addition, the fossils include 15 more objects including the skull bones (frontal and nasal bones), lower jaw fragments and teeth and the upper and lower jaw. It was about 20 cm tall at the shoulder and weighed about 5–6 kg. Generally, ''Eritherium ''shared similarities in the st ...

Proboscidean
The Proboscidea (; , ) are a taxonomic order of afrotherian mammals containing one living family (Elephantidae) and several extinct families. First described by J. Illiger in 1811, it encompasses the elephants and their close relatives. From the mid-Miocene onwards, most proboscideans were very large. The largest land mammal of all time may have been a proboscidean; '' Palaeoloxodon namadicus'' was up to at the shoulder and may have weighed up to , almost double the weight of some sauropods like '' Diplodocus carnegii''. The largest extant proboscidean is the African bush elephant, with a record of size of at the shoulder and . In addition to their enormous size, later proboscideans are distinguished by tusks and long, muscular trunks, which were less developed or absent in early proboscideans. Three species of elephant are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. Elephantidae is the only surviving family of t ...

Daouitherium
''Daouitherium'' ("Sidi Daoui beast" from the name of the site where it was discovered) is an extinct genus of early proboscideans (a group including modern elephants and their extinct relatives) that lived during the early Eocene (Ypresian stage) some 55 million years ago in North Africa. Remains of this animal, fragments of jaws and teeth, have been found in the Ouled Abdoun Basin in Morocco. It is estimated to have weighed between , making it one of the earliest large mammals known from Africa and one of the oldest known proboscideans. Another estimate gives a weight of . Description ''Daouitherium'' is known only from lower jaws and associated cheek teeth. It had lophodont and bilophodont molars, i.e. molars with large ridges. The second and third premolars had a notably large cusp called the hypoconid. Gheerbrant et al. described the teeth as similar to those of other early proboscideans ''Phosphatherium'', ''Numidotherium'', and ''Barytherium''. See also *Fauna of Africa ...

Ouled Abdoun Basin
The Oulad Abdoun Basin (also known as the Ouled Abdoun Basin or Khouribga Basin) is a phosphate sedimentary basin located in Morocco, near the city of Khouribga. It is the largest in Morocco, comprising 44% of Morocco's phosphate reserves, and at least 26.8 billion tons of phosphate. It is also known as an important site for vertebrate fossils, with deposits ranging from the Late Cretaceous (Cenomanian-Turonian) to the Eocene epoch (Ypresian), a period of about 25 million years. Geography The Oulad Abdoun is located west of the Atlas Mountains, near the city of Khouribga. The Oulad Abdoun phosphate deposits encompass some , an area of . The Oulad Abdoun is the largest and northernmost of Morocco's major phosphate basins, which from northeast to southwest, include the Ganntour, Meskala, and Oued Eddahab (Laayoune-Baa) basins. Paleobiota The Oulad Abdoun Basin stretches from late Cretaceous to the Eocene, and contains abundant marine vertebrate fossils, including sharks, bo ...

Numidotherium
''Numidotherium'' ("Numidia beast") is an extinct genus of early proboscideans, discovered in 1984, that lived during the middle Eocene of North Africa some 46 million years ago. It was about 90-100 cm tall at the shoulder and weighed about 250-300 kg. The type species, ''N. koholense'', is known from an almost complete skeleton from the site of El Kohol, southern Algeria, dating from the early/middle Eocene period. The animal had the size and the appearance of a modern tapir. In appearance, it was more slender and more plantigrade than an elephant, its closest modern relative.Libya

Moeritherium
''Moeritherium'' ("the beast from Lake Moeris") is an extinct genus of primitive proboscideans. These prehistoric mammals are related to the elephant and, more distantly, sea cows and hyraxes Hyraxes (), also called dassies, are small, thickset, herbivorous mammals in the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails. Typically, they measure between long and weigh between . They are superficially simi .... They lived during the Eocene epoch.

Tapir
Tapirs ( ) are large, herbivorous mammals belonging to the family Tapiridae. They are similar in shape to a pig, with a short, prehensile nose trunk. Tapirs inhabit jungle and forest regions of South and Central America, with one species inhabiting Southeast Asia. They are one of three extant branches of Perissodactyla (odd-toed ungulates), alongside equines and rhinoceros. Only a single genus, ''Tapirus'' is currently extant. Tapirs migrated into South America during the Pleistocene epoch from North America after the formation of the Isthmus of Panama as part of the Great American Interchange. Tapirs were once widespread in North America until the arrival of humans at the end of the Late Pleistocene, around 12,000 years ago. Species There are four widely recognized extant species of tapir, all in the genus ''Tapirus'' of the family Tapiridae. They are the South American tapir, the Malayan tapir, Baird's tapir, and the mountain tapir. In 2013, a group of researchers said they ...
