Should Aegyptopithecus be in the genus Propliopithecus?
There is controversy over whether or not Aegyptopithecus should be a genus on its own or whether it should be moved into the genus Propliopithecus. Aegyptopithecus zeuxis was a species that had a dental formula of 2:1:2:3 on both the upper and lower jaws, with the lower molars increasing in size posteriorly.
Was Aegyptopithecus an arboreal quadruped?
Aegyptopithecus is thought to have been an arboreal quadruped due to the distal articular region of the femur, which is deeper than that of “later” catarrhines. Also, based on overall femoral morphology, A. zeuxis is thought to have been robust.

What are the characteristics of humerus?

The remains of three women were found in Quarry I (DPC 5262 and 8709) and Quarry M (DPC 2480). Palaeomagnetic dating puts sites on 33 mothers, consistent with the Oligocene epoch.
Is Ezistopithecus a stem catarrhin?
Ezistopithecus is thought to be stem-catarrhin, an important link between the Eocene and the myosin fossils. The Aegyptopithecus has become one of the best extinct primates based on craniodental and postcranial remains.
Is Humaras arboreal a quadratic?
Together with Fimur, the Humaras arboreal suggests quadratics. It is based on muscles stabilizing in the brachial flexor instead of the pronounced brachialis flange and extensor. Also, the ulnar and distal articular surface of the humerus indicates that A. jaxis was large and slow, not just an arboreal quadrant.

Aegyptopithecus Facts
Discovery, Age, and Labor Force
- Allegheny Simmons, In 1966, the Aegyptopithecus was discovered by Alizon Simmons in the Qatrani Formation at Gabel (Egypt’s Arabic Jebel) in the Fayum Governorate of Central Egypt. Originally the Aegyptopithecus fossil was thought to be 35.4 to 33.3 million years old, according to the preliminary analysis of the structure it was found in. However, in the 27rik Eric Seifert analysis, it was decided that the age of the formation of the Gabal Qatrani shou…
Physiology
- Aegyptopithecus was a species that had dental implants 2: 1: 2: 3 in both upper and lower jaws and the lower jaw increased progressively. The molasses showed an adaptation called the computerizing shear, where the cutting edges associated with the buccal phase served to surround the basin in such a way that the food was trapped in pieces. The canin...
The Size of The Brain
- In Egypt’s Fayum disappointment, a subadult female cranium, CGM 85785, was discovered by Rajiv Patnaik. The cranial capacity of this sample was found to be 14.63 cm3, and a re-analysis of a male endocast (CGM 40237) estimated cranial capacity of 21.8 cm3. These estimates remove the precursors of about 30 cm3. These measurements give an estimated male of approximately 1.5 in the endocranial ratio, which identifies A. gexis as …
Behavior
- Emerozypithecus gexasis is thought to be sexually transmitted, indicating tooth size, craniofacial morphology, brain size and body mass. A. Due to the length of the jeuxis sex, the social structure was thought to be multifaceted in intense competition for women.

- The remains of three women were found in Quarry I (DPC 5262 and 8709) and Quarry M (DPC 2480). Palaeomagnetic dating puts sites on 33 mothers, consistent with the Oligocene epoch. The femur is similar to the quadrilateral anthropoid, based on the estimated femoral neck angle (120–130 °) of the aforementioned remains. The morphology of the larger trochanter is incompatible with the primates that serve as further evidence of the a…
Aegyptopithecus Diet
- Studies depending on the chapter on dental microarrays and microspheres suggest that Alegopithecus was probably a frugivore. It is also possible that on some occasions Aegyptopithecus ate the hard stuff.
Habitat
- Aegyptopithecus lived in the Fayum region of northern Egypt. Currently, this area is semi-arid and lacks vegetation. The area was abundant vegetation, colonized, had many trees, and was rained in the Andu during the existence of the Alejosin, Aegyptopithecus.
