It ’s been a bumper year for things uphold in gold withsnails , flowers , ants , and even a whole group ofnew insectsbursting onto the scene . Now , a new roach mintage has been found encased in gold – and it ’s even gross with sperm cell cells . The specimen has been namedSupella dominicanaas it is smother by Dominican amber . This is remember to be the first - ever record of fossilized cockroachsperm .
“ It is well preserved with a yellow cross bar across the wings and a cardinal , upright , yellow stripes that appears to divide the body into two contribution , ” said George Poinar Jr. , professor emeritus in the OSU College of Science who distinguish the specie , in astatement .
" Also of stake is the sperm cell bundle containing spermatozoa with drab acrosomes , structures covering the heading of the spermatozoan , since fossil spermatozoon are rarefied . ”

“ The difficulty in eliminate them from homes once they ’ve film up mansion can cause a portion of stress , ” Poinar suppose . “ Many might say that the best space for a roach is entombed in amber . ”
