Moscow. Pepeluali 11. INTERFAX.RU - Ua ʻike ʻia nā kānaka ʻepekema Kanada mai ka Royal Tyrrell Paleontological Museum i kahi ʻanoʻano hou o ka dinosaur karnivorous, ka mea i kapa ʻia ʻo "Reaper of Death".
"ʻO kēia ka tyrannosaurus mua i loaʻa ma Kanada ma 50 mau makahiki," i ʻōlelo ai ka pou blog moʻomeheu. ʻO ka Re Reapo, i loaʻa ma ka moku ʻoanona o Alberta ma ke komohana o ka ʻāina, ʻokoʻa ka ʻokoʻa e like me nā tyrannosaurs ʻē aʻe i nā ʻano he nui, akā ʻo ka mea e ʻike ʻia nei, he mau kau neʻe i holo i ka lōʻihi o ka iwi o luna, wahi a ke kumu alakaʻi o ka noiʻi, ʻo Jared Voris.
Koho kikowaena o ka tyrannosaurus ma kahi o 2,5 miliona mau makahiki ma mua o kona pili kokoke, a ʻo 79.5 miliona mau makahiki. ʻEhā mau dinosaurs mai Alberta i ʻike ʻia: daspletosaurs, gorgosaurs, albertosaurs a me tyrannosaurs. ʻO ka hapa nui o lākou he 66-77 miliona mau makahiki. Ma ka manawa like, ʻelua mau dinosaurs mai Alberta i ʻike ʻia mai ka neʻe ʻana o ke ola ola o ka "Death Reaper": ka pelekū poʻomanaʻo nui i ka ulia (ʻO Colepiocephale) a me ka diihē pepeXenoceratops).
ʻO ka inoa o nā tyrannosaurus hou Mokuahi likat - e haʻi ana i kāna hana ma ke poʻo o ka pāʻina meaʻai, a ua hoʻohanohano ʻia, ka inoa o ke akua Helene o ka make - Thanatos, i ʻōlelo ʻia ai nā huaʻōlelo - ua hoʻohui ʻia ka ʻili. A ua hāʻawi ʻia ka hapa ʻelua o ka inoa i ka dinosaur hou i mahalo ʻia ai ʻo John De Groot i loaʻa i kāna ʻeha. He mahiʻai ʻo De Groot a he aloha ia o ka paleontology, i ʻole ka ʻōlelo. Loaʻa ʻo ia i kahi iwi, ʻo ia ka mea, i huli ai i ka dinosaur i ka wā o kahi huakaʻi hele ma ke kūkulu hema o Alberta.
"He ʻano kupaianaha loa ka ʻili. Ua ʻike mākou he mea koʻikoʻi loa ia no ka mea ʻike ʻia nā niho fossil," wahi a De Groot.
ʻO kāna wahine ʻo Sandra De Groot, ʻōlelo ʻo kāna kāne ke manaʻoʻiʻo mau nei e loaʻa ia i kahi ʻōpio dinosaur, akā "no ka mea i loaʻa, i loaʻa kekahi ʻano ʻanoʻano o ka dinosaur, aia wale nō i nā palena kūpono."
ʻO Francois Terien, curator o ka keʻena paleoecology o ka dinosaur o ka Royal Tyrrell Paleontological Museum, ʻoiai ke koʻikoʻi nei, "he mea koʻikoʻi kēia ʻike no ka mea e hoʻopiha ana i ka hakahaka o kā mākou ʻike ma ka hoʻomohala o nā tyrannosaurs." Hāʻawi ka Reaper o ka make i kahi ʻike o ka lāʻau kūloko o nā tyrannosaurs a hōʻike ʻia i nā tyrannosaurs mai ka manawa Cretaceous o Alberta he ʻokoʻa ka ʻoi aku ma mua o ka manaʻo i hana ʻia, i ʻōlelo ʻia ai ka hale moʻomeheu.
ʻOluʻolu make
Ua hōʻike ʻia e ka paleontologists China i loko o ka cartilage i hoʻohuli ʻia o ka dinosaur, ua hōʻike lākou i nā microstructure e like me ka pūleo a me nā chromosome o nā pā. Ua noi aku nei nā kānaka ʻepekema ma loko o ka palapala fossil i mālama pono ʻia o nā sel chondrocyte. Hōʻike ʻia nā hualoaʻa o nā loiloi ʻo nā māhele o ka matrix extracellular o ka cartilage, me ka glycosaminoglycans a me ke ʻano II collagen, mālama ʻia kekahi. Ua hōʻoia i kekahi mau hōʻike i ka hiki ʻana o ka DNA i ka fossil: nā mākaʻikaʻi e pili pono ana i nā kiko genetic i hoʻopaʻa ʻia. Akā, ua hōʻoia nā mea kākau i ka hiki ke kūlohelohe o ka waiwai, ʻoiai lākou e manaʻo nei i ka mea hiki ʻole.
Eia naʻe, manaʻoo kekahi mau mea loea e hiki ke hoʻohālikelike i nā hiʻohiʻona. Ua ʻike ʻo Evan Saitta o ka Hale Hōʻikeʻike o ka Mānāwai ma Chicago i ka hopena o nā kime o nā Kina e hiki ke hoʻopili ʻia e nā hewa helu a me ka hele ʻana o nā mikrob i ka mea i hoʻopaʻa ʻia ʻia. ʻO ka did propidium iodide (PI) i hoʻohana ʻia ma ka hoʻopaʻa ʻana ʻaʻole hiki ke komo i nā membran cell, no laila ke noho nei ʻaʻole hiki ke manaʻo ʻia he mau hōʻike no ka noho ʻana o ka DNA i loko o ka nucleus cell. I ka manawa like, momona nā iwi huaʻai i ka microbial DNA, hiki ke ʻike i ka hoʻohana ʻana iā PI. Hoʻolālā nā loea mōʻaukala hana i mea e hōʻoia ai i ka loaʻa ʻana o ka cartilage i ka hopena no ka hāʻawi ʻana i nā hopena kūpono ʻole.
Eia naʻe, ʻaʻole kūlike ka poʻe kākau o ka hana i ka loiloi. "Hiki iā lākou ke ʻōlelo i kā lākou makemake," i ʻōlelo ʻia ai ka poʻe kānalua ʻo Mary Schweitzer o ke Kulanui o North Carolina. Manaʻoʻo ia ua hōʻike maoli nā māka i ka hele ʻana o ka DNA i loko o nā kaola cellular ma ke kumu o ka cartilage, ka mea i hōʻike ʻia i mua me nā ʻano o nā moʻolelo a me nā immunological.
