 Ary karazana lalomena fôsily sasany tany Indônezia niaina tamin' ny vanim-potoana Pleistôsena

Ary ho an' ny mpanoratra sasany, karazana lalomena afrikana roa, ny iray amin' izy ireo izay mbola misy, dia anisan' ity sokajy ity:

 Hexaprotodon liberiensis - lalomena pigmea afrikana
 Hexaprotodon madagascariensis † - lalomena malagasy

Ho an' ny mpanoratra hafa dia anisan' ny vondron-karazana Choeropsis ireo karazana roa ireo na anisan' ny Hippopotamus raha ho an' ny lalomena malagasy ihany. Ny lalomena pigmea ankehitriny dia novana sokajy ka nampidirina vao haingana ao amin' ny vondron-karazana Choeropsis tamin' ny taona 2021 taorian' ny famakafakana vaovao, saingy mpanoratra maro no manohy mampiasa ny karazana Hexaprotodon ho an' ity karazana ity. Mbola misy ny adihevitra momba ny fanasokajiana marina ireo biby ireo.
