Ua aʻo ka poʻe Paleontologists i kekahi mau mōʻalihaku o ʻekolu mea hou i ka ʻepekema ichthyosaurs (kai dinosaurs), ʻoi aku paha ka nui ma mua o nā holoholona āpau i ola ma ka honua. Ua loaʻa nā mea i loaʻa ma Swiss Alps ma waena o 1976 a me 1990 - akā ua aʻo ʻia i kēia manawa. ʻO kēia ka niho ichthyosaur nui loa i ʻike ʻia. ʻElua ia o ka nui o ka niho haʻi moʻolelo o ka ichthyosaur, he mea kolo he 15 mika ka lōʻihi. No laila, ua manaʻo ʻia ʻo ka ichthyosaur a lākou e aʻo nei i kēia manawa he ʻelua paha ka nui. ʻO nā koena iwi ʻē aʻe ʻaʻole i hoʻopiha ʻia ka vertebra ichthyosaur nui loa i ʻike ʻia ma ʻEulopa. ʻOi aku ma mua o 200 miliona mau makahiki i hala aku nei, ua uhi ʻia nā papa pōhaku kahi i ʻike ʻia ai ke koena i ke kai. Akā me ka hoʻokumu ʻana o nā Alps ma kahi o 35 miliona mau makahiki i hala, ua ʻike lākou iā lākou iho ma kahi kiʻekiʻe o 2800 mika. ʻO ka poʻe mākaʻikaʻi makaʻu ʻole o Swiss e hele i nā pali alpine hau a lawe i nā koena o nā monsters kai kahiko ma ko lākou poʻohiwi e wehewehe iā lākou i ke kaiāulu ʻepekema. Akā ʻo ia ʻike kūʻokoʻa i kūpono i ka hoʻoikaika ʻana.
ʻO Ichthyosaurs, nā mea kolo he 80-toni, noho ʻo Pantalasa, ka moana honua a puni ka ʻāina nui o Pangea i ka Triassic hope loa, ma kahi o 205 miliona mau makahiki i hala. Ua "paʻi" lākou ma nā wai pāpaʻu o ka Moana Tethys a hiki i ka ʻaoʻao hikina o Pangea, e like me ka mea i ʻike ʻia e nā mea hou. Ua like ke ʻano me nā koholā hou, he mau kino lōʻihi ko ichthyosaurs a me nā peʻa huelo kūpaʻa. Loaʻa kēia mau ʻano nunui i ka nui loa ma ʻAmelika ʻĀkau. He nui nā mea i loaʻa ma ka Himalayas a me ka Pākīpika Hema. Ma kēia ʻano, ʻokoʻa ka loaʻa ʻana o nā pilikua hou ma Switzerland a hoʻonui nui hoʻi i ka laulā maʻamau o kēia mau moʻo kai kahiko. No ka liʻiliʻi o ka ʻike e pili ana i kēia mau pilikua, ua like lākou me nā ʻuhane i ka paleontology. ʻOiai ka nui o kā lākou mau mōʻalihaku, ʻike liʻiliʻi loa ka poʻe paleontologists e pili ana i kēia mau mea kolo kahiko. Mahalo i ka ʻike hou, manaʻolana ka poʻe ʻepekema e hoʻohui i ko lākou ʻike no nā ichthyosaurs nunui, a me ka loaʻa ʻana o nā mōʻalihaku i mālama ʻia.
