Females: average 3 ft 11 inches (120 centimeters)
Females: average 110 lbs (50 kg)
Height & Weight Supplemental Information:
The only body size estimate scientists have made so far is based on the partial female skeleton ARA-VP-6/500 ("Ardi"). She is estimated to have stood 3 ft 11 in (120 cm) tall, weighed approximately 110 lbs (50 kg). Based on the size of the upper canine teeth in males is not much larger than the canines of females, scientists don’t expect Ar. ramidus to have shown much body size sexual dimorphism - so a male individual would have been similar to a female in size. It’s possible that Ar. ramidus males did not compete against each other for dominance, and therefore did not need to grow bigger in size.
