 Because Mesopropithecus died out relatively recently and is only known from subfossil remains , it is considered to be a modern form of Malagasy lemur . It may have been among the last subfossil lemurs to go extinct , possibly surviving until 500 years ago , although radiocarbon dating places the most recent remains at 570 – 679 CE for a M. pithecoides from Ampasambazimba . The arrival of humans roughly 2 @,@ 000 years ago is thought to have sparked the decline of Mesopropithecus through hunting , habitat destruction , or both .
