Ke kū ʻoe ma ka ʻaoʻao o kahi cycad, a i ʻole e nānā i luna e ʻike i kahi manu liʻiliʻi e lele ana ma mua - ua noʻonoʻo paha ʻoe: ua ʻike mua kēia mau ola maʻamau i ke au o nā dinosaur? ʻO lākou nā "fossils ola" e kaʻana like ana i ko kākou honua, nā "kamaʻāina" maoli mai ka wā dinosaur. I kēia lā, e ʻike kākou i kēia mau "hoalauna dinosaur" i hala i nā haneli miliona mau makahiki a ke noho pū nei me kākou.
Ka Moʻokūʻauhau Kahiko o nā Mea Kanu
He mea nui nā Cycads ma ka papa ʻaina dinosaur. Hiki ke hoʻi ʻia ko lākou kumu i ka wā Devonian, ma kahi o 350 miliona mau makahiki i hala. ʻO ka hapa nui o nā mōlina cycad i loaʻa i kēia lā mai ka Permian mai, akā ua kaulana lākou i ka honua holoʻokoʻa i ka wā Mesozoic, mai ka Triassic a i ka Cretaceous. ʻO ko lākou mau lau paʻakikī, huluhulu a me nā kumu waiwai i ka starch i hāʻawi i ka ikehu nui no nā dinosaur herbivorous nui. Ma nā moena mōlina dinosaur ma Kina - me Zigong lāua ʻo Gansu - ʻike pinepine nā kānaka ʻepekema i nā mōlina lau cycad i mālama ʻia me nā kapuaʻi a me nā iwi dinosaur.
He moʻolelo kaʻao ʻo Ginkgo i loko o ke aupuni mea kanu - ʻo kona papa, kauoha, ʻohana, a me ke ʻano he hoʻokahi wale nō ʻano ola: ʻo Ginkgo biloba, kū hoʻokahi maoli. Ua ʻike mua ʻia ka ginkgo ma kahi o 345 miliona mau makahiki i hala aku nei i ka wā Carboniferous a ua laha ākea ma ka honua holoʻokoʻa i ka wā Mesozoic. I loko o nā mōʻalihaku mua o ka Cretaceous o Jehol Biota i ʻike ʻia ma ka moku ʻo Liaoning, ua loaʻa nā lau ginkgo i kanu pū ʻia me nā dinosaur hulu manu a me nā manu mua. ʻO ke ola ʻana o ka ginkgo a hiki i kēia lā ma muli o kona kūpaʻa kupaianaha: nā hui kemika i loko o kona mau lau e kūʻē i nā mea ʻino a me nā maʻi, ʻoiai ʻo ka papa waho o kona mau hua he mau mea antibacterial. I ka hopena o ka hāʻule, ʻo kēlā mau lau gula, ʻano peʻahi he aloha i hoʻouna ʻia ma nā haneli miliona mau makahiki.
ʻO Metasequoia (lāʻau ʻulaʻula kakahiaka), Sequoia (lāʻau ʻulaʻula kahakai), Sequoiadendron (sequoia nui), a me nā ʻano cypress he nui a lākou i loaʻa nā kūpuna pololei i ulu pū me nā dinosaur. Ma ka Petrified Forest National Park kaulana ma ke komohana o ʻAmelika Hui Pū ʻIa, ua hoʻi ka lāʻau petrified nui i ka Late Triassic—ʻo ia ka wā i hoʻomaka ai nā dinosaur i ko lākou piʻi ʻana. ʻO kēia mau lāʻau kiʻekiʻe i hoʻokumu i nā ʻāina ululāʻau mua kahi i noho ai nā dinosaur. ʻO ka ʻike ʻia ʻana o Metasequoia ma ka moku ʻo Hubei, Kina, i ka makahiki 1941 he mea kupaianaha loa - ua kapa ʻia ʻo ia he "fossil ola" no ka mea ua manaʻoʻiʻo nā kānaka ʻepekema ua pau ia, ʻike wale ʻia mai ka moʻolelo fossil.
Nā Laina Koko Kahiko ma ke Aupuni Holoholona
He ʻano like ko nā crocodiles hou, nā alligators, a me nā gharials i ke ʻano a me ke ʻano o ko lākou mau kūpuna Cretaceous. No ka laʻana, ua noho ʻo Sarcosuchus kaulana ma kahi o 110 miliona mau makahiki i hala aku nei ma ʻApelika, a hiki i ka lōʻihi a hiki i 12 mika a kū ma ke ʻano he mea ʻaihue kiʻekiʻe o kona manawa. Ua hōʻoia ʻia kā lākou hoʻolālā hahai holoholona semi-aquatic, ambush-leading he "hoʻolālā" holomua loa, i hoʻoili mau ʻia ma o nā loli koʻikoʻi o ke kaiapuni. ʻO ka puʻuwai ʻehā keʻena paʻakikī o ka crocodile a me nā ʻano metabolic kū hoʻokahi nā ʻano i kōkua iā lākou e ola i ka hanana luku nui ʻana he 66 miliona mau makahiki i hala.
ʻO ka tuatara, e noho ana ma kekahi mau mokupuni o Aotearoa, ʻo ia wale nō ka ʻelele ola o ke kauoha Rhynchocephalia. He ʻano like ʻole kēia hui i ka wā Triassic, e noho pū ana me nā dinosaur mua. Ua lohi loa ka wikiwiki o ka ulu ʻana o ka tuatara - ʻo kona ʻano iwi poʻo a me ke kolu o ka "maka parietal" (kahi ʻōkana ʻike mālamalama) ua aneane like me ko kona mau kūpuna fossil mai 200 miliona mau makahiki i hala. ʻO ke aʻo ʻana i ka tuatara ua like ia me ka nānā ʻana ma o ka puka makani ola i loko o nā mea kolo mua o ka wā dinosaur.
ʻOiai lākou e noho ana i loko o ke kai, he mea kupanaha ka noho ʻana o nā pāpaʻi lio. No ka subphylum Chelicerata lākou, e pili loa ana iā lākou me nā nananana a me nā moʻo ʻino ma mua o nā pāpaʻi maoli. ʻO nā kūpuna fossil o nā pāpaʻi lio mai ka Ordovician mai, a ua hoʻokumu ʻia ke ʻano pāpaʻi lio hou ma kahi o 200 miliona mau makahiki i hala. He mea waiwai nui ko lākou koko polū kū hoʻokahi (loaʻa nā iona keleawe) no ka hoʻāʻo ʻana i ke olakino. ʻOiai nā dinosaur e noho aliʻi ana ma ka ʻāina, ua auwana nā kūpuna o nā pāpaʻi lio ma nā kai pāpaʻu - a ke mālama nei lākou i ke ʻano like i kēia lā.
ʻOi aku kēia mau "hoalauna dinosaur" ma mua o nā mea kupanaha. He mau waihona ola lākou o ka mōʻaukala evolutionary o ka Honua. I loko o ko lākou genomes, nā ʻano hana physiological, a me nā kuleana ecological e waiho ana i nā kī i ka hoʻomaopopo ʻana i nā hoʻolālā hoʻololi o ke ola kahiko. I ka manawa like, nui o lākou e kū nei i nā hoʻoweliweli hou e like me ka luku ʻia ʻana o nā wahi noho a me ka loli o ke aniau. ʻO ka pale ʻana iā lākou ʻo ia hoʻi ka pale ʻana i kahi moʻolelo kū hoʻokahi o ke ola.
I ka manawa aʻe e ʻike ai ʻoe i nā aʻa o ka lau ginkgo, a i ʻole e kahaha i ka nānā kahiko o kahi moʻo, e hoʻomanaʻo - ke hoʻopā nei ʻoe i kahi hoʻomanaʻo ola e pili ana i ke au o nā dinosaur. Aia lākou ma ʻaneʻi, e noho pū ana me mākou, e haʻi ana i kahi moʻolelo o ka hohonu o ka manawa a me ke kūpaʻa o ke ola.
Ka manawa hoʻouna: Iulai-28-2026
