A recent discovery of an ancient jawbone in northern Egypt has the potential to transform our understanding of human and ape evolution. The fossil, belonging to a previously unidentified species dubbed Masripithecus moghraensis, is estimated to be between 17 and 18 million years old. This finding is significant as it marks the first conclusive ape fossil found in North Africa from this era, offering new insights into the origins of modern apes and their common ancestors.

The jawbone was uncovered by researchers on expeditions conducted in 2023 and 2024 at Wadi Moghra, a site renowned for its rich fossil deposits. While ancient monkey remains have previously been discovered in the area, this is the first definitive evidence of an ape from this timeframe. The naming of Masripithecus reflects its geographical significance; “Masr” is the Arabic term for Egypt, and “moghraensis” indicates its discovery site.
Hesham Sallam, a paleontologist at Mansoura University and principal author of a study detailing the discovery, expressed the excitement surrounding the find. “For five years, we have been searching for fossils like this. It has become increasingly clear that North Africa holds crucial pieces of the early ape family tree,” he stated, emphasising the significance of this discovery in the context of evolutionary studies.
The jaw fragment recovered from the site revealed remarkable features that provide insight into the creature’s diet and lifestyle. The species possessed a robust jaw structure, accompanied by large canine and premolar teeth, along with rounded molars. These characteristics suggest that Masripithecus had a diet primarily consisting of fruit, although it could also process tougher foods such as nuts and seeds when necessary. This dietary versatility may have been advantageous in adapting to the varying seasonal conditions in its ancient environment.
In their pursuit to fit Masripithecus moghraensis into the evolutionary family tree, the research team conducted detailed comparisons of anatomical traits, genetic data from extant apes, and ages of known fossil specimens. Interestingly, their analysis indicated that this newly discovered species could be more closely related to modern apes than any previously identified ape species from the Early Miocene period in East Africa.
This discovery invites a reevaluation of the long-held notion that the common ancestors of all living apes originated in East Africa. Erik Seiffert, a paleontologist at the University of Southern California and co-author of the study, acknowledged the impact of this finding on established beliefs. “For much of my career, I believed that the common ancestor of all living apes likely lived in or around East Africa. However, this new discovery, alongside our refined analyses of hominoid phylogeny and biogeography, strongly challenges that idea,” he remarked.
It is important to note that the researchers do not suggest that Masripithecus moghraensis is a direct ancestor of modern humans or apes. Instead, this fossil provides valuable information regarding a much earlier segment of evolutionary history, prior to the divergence of various ape lineages. With the current material limited to a jaw fragment, scientists remain uncertain about the overall appearance and locomotion of Masripithecus.
Looking ahead, researchers are optimistic that future excavations in North Africa and the Middle East will yield additional findings that could refine our understanding of the evolutionary path leading to contemporary apes. “The scenario we’re presenting is not solely dependent on Masripithecus; rather, it aligns with the broader patterns we observe in apes,” Seiffert concluded, indicating that continued research could reveal more about the ancient origins of our primate relatives.
As more evidence comes to light, these findings underscore the importance of considering diverse geographical areas such as North Africa in the study of primate evolution. In doing so, scientists may uncover further details that enrich our comprehension of how the ancestors of today’s apes evolved and adapted to their environments millions of years ago.
