“…Judged against known age Virunga mountain gorillas at broadly the same stage of dental development, TM 1517 would fall between the ages of 10.69 and 14.94 years at the time of death (Boughner et al, 2012;Kralick et al, 2017) while, by assuming a Gorilla-like skeletal developmental model, TM 1517 would be younger than 8.5 years, if female, and between 9 and 12.5 years, if male (Leigh, 1992). When the Pan pattern is considered as a compatible model, TM 1517 would be 7.01-10.75 year old dentally (Boughner et al, 2012;Kuykendall & Conroy, 1996) and between 7.95 and 13.5 years old based on its skeletal maturation (Brimacombe et al, 2015(Brimacombe et al, , 2018Cameron et al, 2017).…”
