from carnivore kills. Others like Henry Bunn believe the hominins hunted and killed these animals, and carnivores later chewed the bones. This issue is still debated today, but archaeologist Pat Shipman provided evidence that scavenging was probably the more common practice; she published that the majority of carnivore teeth marks came before the cut marks. Another finding by Shipman at FLK-Zinj is that many of the wildebeest bones found there are over-represented by adult and male bones; and this may indicate that hominins were systematically hunting these animals as well as scavenging them. The issue of hunting versus gathering at Olduvai Gorge is still a controversial one.

Eng. Joshua Mwankunda conceived the idea of erecting a monument to commemorate this significant site while also serving as a signpost and attracting visitors to the Olduvai Gorge and museum; paleoanthropologists Nicholas Toth, Kathy Schick, and Jackson Njau planned and provided life-size fossil casts at the request of the Tanzanian government, which were used by the celebrated Tanzanian artist Festo Kijo to create the two large concrete skulls. The monument consists of two large-scale models of fossil skulls which sit atop a large pedestal with an informative plaque mounted on the side of the pedestal. The fossil skulls depicted are Paranthropus boisei and Homo habilis, two contemporary species which were first discovered at Olduvai Gorge. The large-scale models created by Kijo are each 6 feet tall and weigh 5,000 pounds. The monument project was funded by the Stone Age Institute and the John Templeton Foundation, in partnership with the Ngorongoro Conservation Area Authority (NCAA). The Olduvai Gorge Museum, located 5 km beyond the monument, is situated on the rim of the gorge at the junction of the main gorge and the side gorge. As one of the largest onsite museums in Africa, the museum provides educational exhibits related to the gorge and its long history.
