Pterosauria: ʻAʻole wau he "dinosaur lele"
I ko mākou ʻike ʻana, ʻo nā dinosaur nā aliʻi o ka honua i ka wā kahiko. Manaʻo mākou he mea maʻamau ka hoʻokaʻawale ʻia ʻana o nā holoholona like i kēlā manawa i loko o ka māhele o nā dinosaur. No laila, ua lilo ka Pterosauria i "nā dinosaur lele". ʻO ka ʻoiaʻiʻo, ʻaʻole ʻo Pterosauria he dinosaur!
ʻO nā dinosaur e pili ana i kekahi mau reptile ʻāina e hiki ke hele pololei, koe naʻe nā pterosaurs. He mau reptile lele wale nō ʻo Pterosauria, a me nā dinosaur ʻelua no nā lālā ulu o Ornithodira. ʻO ia hoʻi, ua like nā pterosauria a me nā dinosaur me nā "hoahānau". He mau hoahānau pili lākou, a he ʻelua mau ʻaoʻao ulu i noho i ka wā like, a ʻo ko lākou kūpuna hou loa i kapa ʻia ʻo Ornithischiosaurus.
Hoʻomohala ʻēheu
Ua noho aliʻi ʻia ka ʻāina e nā dinosaur, a ua noho aliʻi ʻia ka lewa e nā pterosaurs. He ʻohana lākou, no ke aha i noho ai kekahi ma ka lewa a ʻo kekahi ma ka honua?
Ma ke komohana o ka Panalāʻau ʻo Liaoning ma Kina, ua loaʻa kahi hua manu pterosauria i ʻoki ʻia akā ʻaʻole i hōʻike i nā hōʻailona o ka haki ʻana. Ua ʻike ʻia ua ulu maikaʻi nā membrane ʻēheu o nā embryos i loko, ʻo ia hoʻi, hiki i ka pterosauria ke lele koke ma hope o ka hānau ʻana.
Ua hōʻike ʻia e ka noiʻi a nā loea he nui ua ulu ka pterosauria mua loa mai nā mea holo ʻāina liʻiliʻi, ʻai pepeke, wāwae lōʻihi e like me Scleromochlus, nona nā membrane ma ko lākou mau wāwae hope, e hohola ana i ke kino a i ʻole ka huelo. Ma muli paha o ka pono no ke ola a me ka ʻai ʻana i nā mea ʻai, ua lilo ka ʻili o lākou i mea nui a ulu mālie i ke ʻano e like me nā ʻēheu. No laila hiki ke hoʻokuke ʻia i luna a ulu mālie i nā mea kolo lele.
Ua hōʻike nā iwi kuamoʻo ʻaʻole wale kēia mau manu liʻiliʻi he liʻiliʻi, akā, ʻaʻole maopopo ke ʻano o ka iwi ma nā ʻēheu. Akā, ua ulu mālie lākou i ka lewa, a ua pani mālie ka ʻēheu nui, ʻo Pterosauria lele huelo pōkole i nā "dwarfs", a ma hope ua lilo i ka mana o ka lewa.
I ka makahiki 2001, ua ʻike ʻia kahi mōlina pterosauria ma Kelemania. Ua mālama hapa ʻia nā ʻēheu o ka mōlina. Ua hoʻomālamalama nā kānaka ʻepekema iā ia me ka mālamalama ultraviolet a ʻike ʻia he membrane ʻili kona mau ʻēheu me nā kīʻaha koko, nā ʻiʻo a me nā olonā lōʻihi. Hiki i nā olonā ke kākoʻo i nā ʻēheu, a hiki ke huki paʻa ʻia ka membrane ʻili, a pelu ʻia paha e like me ka peʻahi. A i ka makahiki 2018, ua hōʻike ʻia ʻelua mau mōlina pterosauria i ʻike ʻia ma Kina he mau hulu mua ko lākou, akā ʻaʻole e like me nā hulu o nā manu, ua liʻiliʻi a ʻoi aku ka palupalu o ko lākou hulu i hiki ke hoʻohana ʻia e mālama i ka mahana o ke kino.
Paʻakikī ke lele
Ua ʻike anei ʻoe? Ma waena o nā mōlina i loaʻa, hiki i ka laulā o nā ʻēheu o nā pterosauria nui ke hoʻonui i 10 mika. No laila, manaʻo kekahi poʻe loea inā he ʻelua ʻēheu ko lākou, ʻaʻole hiki i kekahi pterosauria nui ke lele lōʻihi a mamao loa e like me nā manu, a manaʻo kekahi poʻe ʻaʻole loa lākou e lele iki! No ka mea, ua kaumaha loa lākou!
Eia nō naʻe, ʻaʻole i maopopo loa ke ʻano o ka lele ʻana o ka pterosauria. Kuhi pū kekahi poʻe ʻepekema ʻaʻole paha i hoʻohana ka pterosauria i ka holo ʻana e like me nā manu, akā ua ulu kūʻokoʻa ko lākou mau ʻēheu, e hana ana i kahi ʻano aerodynamic kū hoʻokahi. ʻOiai ua pono nā pterosauria nui i nā lālā ikaika e iho ai mai ka honua, akā ua kaumaha loa nā iwi mānoanoa. Ma hope koke iho, ua ʻike lākou i kahi ala! Ua ulu nā iwi ʻēheu o ka pterosauria i loko o nā ʻōmole hakahaka me nā paia lahilahi, kahi i hiki ai iā lākou ke "lilo i ke kaumaha" me ka holomua, e lilo i mea maʻalahi a māmā hoʻi, a hiki ke lele maʻalahi.
Wahi a kekahi poʻe ʻaʻole hiki i ka pterosauria ke lele wale, akā lele i lalo e like me nā ʻaeto e ʻai i nā iʻa mai ka ʻili o nā moana, nā loko, a me nā muliwai. ʻO ka lele ʻana i hiki ai i ka pterosauria ke hele i nā wahi lōʻihi, pakele i nā mea ʻaihue a hoʻomohala i nā wahi noho hou.
