An almost entire skeleton of a male individual of Nacholapithecus kerioi (KNM-BG 35250) was discovered from Middle Miocene (approximately 15 Ma) sediments at Nachola, northern Kenya. N. kerioi exhibits a shared derived subnasal morphology with living apes. In many postcranial features, such as articular shape, as well as the number of the lumbar vertebrae, N. kerioi resembles Proconsul heseloni and/or P. nyanzae, and lacks suspensory specializations characteristic of living apes. Similarly, N. kerioi shares some postcranial characters with Kenyapithecus spp. However, despite the resemblance, N. kerioi and Proconsul spp. are quite different in their body proportions and some joint morphologies. N. kerioi has proportionally large forelimb bones and long pedal digits compared to its hindlimb bones and lumbar vertebrae. Its distinctive body proportions suggest that N. kerioi was more derived for forelimb dominated arboreal activities than P. nyanzae and P. heseloni. On the other hand, it exhibits a mixture of derived and primitive cranio-dental and postcranial features relative to the contemporaneous Kenyapithecus and Early MioceneMorotopithecus. While the phylogenetic position of N. kerioi is unsettled, it seems necessary to posit parallel evolution of cranio-dental and/or postcranial features in fossil and living apes.

来自肯尼亚中新世的Nacholapithecus骨骼。

在肯尼亚北部纳霍拉的中新世中期（约15 Ma）沉积物中发现了纳霍拉氏梭鱼（KNM-BG 35250）的男性个体的几乎整个骨骼。角膜猪笼草与活猿类表现出共享的鼻下形态。在许多颅后特征中，例如关节形状以及腰椎骨的数量，角膜猪笼草与黑头刺鼠和/或nyanzae相似，并且缺乏活体猿的悬浮专长。同样，凯里猪笼草与肯雅皮氏菌属有一些颅后特征。然而，尽管有相似之处，但N. kerioi和Proconsul属。他们的身体比例和某些关节形态完全不同。与后肢骨骼和腰椎骨相比，凯里猪笼草具有成比例的大前肢骨骼和长脚趾手指。它独特的身体比例表明，比起P. nyanzae和P. heseloni，角头猪笼草的前肢占主导地位的树栖活动更多。另一方面，相对于同时期的肯尼亚上古猿和中新世早期的古代上古猿，它表现出派生的和原始的颅牙和颅后特征的混合体。虽然角膜猪笼草的系统发育位置尚未确定，但似乎有必要在化石和活猿中假定颅齿和/或颅后特征平行发展。
