 The fossil record for bees is very incomplete , but by 2012 some 11 specimens that might possibly be Bombini , some poorly documented , had been described ; some ( such as <unk> <unk> from Florissant , USA , and <unk> <unk> from <unk> , Turkey ) dated from the Oligocene . In 2012 a fossil bumblebee , Bombus ( Bombus ) <unk> was found in the Miocene rocks of the <unk> Maar in southwestern Germany and confidently placed in the subgenus Bombus . In 2014 , a new bumblebee , Bombus <unk> , was described from Late Miocene lacustrine beds of La <unk> , Spain , while another , <unk> cuspidatus was described from the late Eocene Bembridge <unk> of the Isle of Wight .
