Name the early Miocene apes
Proconsul
Ekembo
Afropithecus
Heliopithecus
Morotopithecus
Heliopithecus
When
What
Who related to
Early Miocene
-pretty much identical to Afropithecus
-larger molars with rounder cusps
-Saudi Arabia
Morotopithecus
-fenestrated windows
-dentition similar to Ekembo
-lumbar vertebrae intermediate to monkeys and apes
-cingula and thinner enamel
Griphopithecus
Large, robust jaws
-thick enamel
-low EDJ (no horns)
-flattened enamel surface
-terrestrial resources, hard and tough and gritty food wear down
-Turkey
-Ekembo-like post crania based on Griphopithecus
-pronograde quadrupedalism
-first to leave Africa
Equatorius
similar to Gripho. But in Africa
-from Kenya
-16-15mya
-massive jaws
-thick enamel and low EDJ
-post-crania
-primitive limbs like Ekembo
-ulna with large olecranon process
-lower end of the ulna has a prominent styloid process for a stable wrist
-posterior humeral head like a monkey
Nacholapithecus
-similar dentally
-small shelf-like cingula
-joints are relatively large in the forelimb and smaller in the hindlimb
-zygomatic root still low
-ape-like body plan starts to form
-distal end of humerus, proximal end of the ulna, proximal end of a femur
-Afropithecus like canines
Kenyapithecus
high zygomatic root
-hominids (g. Apes and humans)
-youngest of the thick middle Miocene, low dentin penetrance
-distal end of a humerus
-not super distinct capitulum, asymmetrical …arboreal still
-No cingulum
-thicker canines than other griphopiths
-elongated molars
Who had the first high zygomatic root
Kenyapithecus
Who the mid Miocene
Griphopithecus
Nacholapithecus
Kenyapithecus
Equatorius
Otavipithecus

Relic of proconsul radiation maybe ?

-size of teeth like Ekembo
-female
Pierolapithecus
relatively straight proximal phalanx
-possibly suspensory but not super sure
-more modern in premaxilla with overlapping maxilla and premaxilla (stepped subnasal fossa)
-reduced incisive foramen
-teeth revert to Ekembo-like
-thinner animal but high Dentin Penetrance
Anoiapithecus
more modern in premaxilla with overlap
-reduced incisive foramen
-teeth revert to Ekembo-like
-thinner animal but high Dentin Penetrance
