Final answer:
Proconsul africanus africanus and Sivapithecus are Asian forms of Miocene hominoids. They lacked a tail and had a strong resemblance to orangutans.
Step-by-step explanation:
The Asian forms of Miocene hominoids include Proconsul africanus africanus and Sivapithecus. Proconsul Africanus Africanus is an early Miocene ape that lived in Africa and lacked a tail. Sivapithecus fossils have been found in Asia, particularly in Turkey, and show a strong resemblance to orangutans. These apes had thick dental enamel and exhibit similar nasal openings and eye sockets to modern orangutans.
