Hoʻolauna iā Smilosuchus

ʻO Smilosuchus kahi ʻano mea kolo o nā mea kolo e like me ka crocodile i ola i ka wā Late Triassic, ma kahi o 235 a 210 miliona mau makahiki i hala. Aia ia i ka hui i kapa ʻia ʻo phytosaurs, he mau mea kolo semi-aquatic i like me nā crocodiles. Ua ʻike mua ʻia ʻo Smilosuchus ma ke komohana hema o ʻAmelika Hui Pū ʻIa, ma New Mexico a me Arizona. Ua ʻike ʻia no kāna mau hiʻohiʻona kūʻokoʻa, kahi i hoʻokaʻawale iā ia mai nā phytosaurs ʻē aʻe a hāʻawi i nā ʻike waiwai i nā kaiaola kahiko i noho ai.

Nui a me ke kino o Smilosuchus

He mea kolo nui ʻo Smilosuchus, me nā mākua hiki i ka lōʻihi ma kahi o 5 a 6 mau mika. He kino paʻa a lōʻihi kona kino, i hoʻololi maikaʻi ʻia no ke ʻano ola wai. He pōkole kona mau lālā a kū i nā ʻaoʻao o ke kino, e hiki ai ke neʻe pono i ka wai. Ua uhi ʻia ke kino o Smilosuchus i nā papa iwi, i kapa ʻia ʻo osteoderms, ka mea i hoʻomalu i nā mea ʻaihue a lilo i mea hoʻoponopono wela.

ʻO ke ʻano o ka iwi poʻo a me nā niho o Smilosuchus

ʻO ka iwi poʻo o Smilosuchus kekahi o kona mau hiʻohiʻona. He ihu lōʻihi a haiki kona, piha i nā niho ʻoi he nui. ʻO nā niho he ʻano conical a ʻoʻo i hope, e hiki ai iā Smilosuchus ke hopu a paʻa i kāna mea pio. Ua hōʻike ʻia ka iwi poʻo i nā puka nui, i kapa ʻia ʻo fenestrae, ka mea i hoʻemi i kona kaumaha a ʻae ʻia no nā ʻiʻo ʻāwae ikaika. ʻO kēia mau hoʻololi ʻana ua lilo ʻo Smilosuchus i mea ʻaihue weliweli i kona kaiaola.

ʻO ke ʻano o nā lālā a me ka holo ʻana o Smilosuchus

ʻAʻole e like me nā crocodiles hou, nona nā lālā ākea, ua hoʻonoho ʻia nā lālā o Smilosuchus ma lalo pono o kona kino, e ʻae ai i kahi hele ʻoi aku ka maikaʻi a me ka agile. Hōʻike kēia ʻano lālā i hiki iā Smilosuchus ke hele ma ka ʻāina a ʻauʻau i ka wai. Ua lako kona mau lala me na maiuu oi, i kokua i ka hopu ana a me ka paa ana i ka mea pio. ʻO ka hui pū ʻana o kona ʻano lālā a me nā ʻiʻo huelo ikaika i hiki iā Smilosuchus ke neʻe wikiwiki i kona kaiapuni.

ʻO ka ʻai a me ka hana hānai ʻana o Smilosuchus

He mea kolo ka Smilosuchus, e hānai nui ana i nā iʻa a me nā mea waiwai ʻē aʻe. ʻO kona ihu lōʻihi a haiki, piha i nā niho ʻoi, ua kūpono no ka hopu ʻana a me ka paʻa ʻana i nā mea pahee. Ua hoʻohālua paha ʻo Smilosuchus i kāna mea pio, me ka hoʻohana ʻana i kona mau ʻāʻī ikaika e hana i ka nahu wikiwiki a make. Hōʻike ʻia nā moʻolelo mōʻalihaku ʻo Smilosuchus paha he mea ʻai kanaka, ʻoiai ua loaʻa nā koena o nā mea liʻiliʻi i loko o ka ʻōpū o nā kānaka nui.

Noho a me ka mahele ʻana o Smilosuchus

Ua loaʻa nā mōʻalihaku Smilosuchus ma ke komohana hema o ʻAmelika Hui Pū ʻIa, ʻo ia hoʻi ma ka Chinle Formation o New Mexico a me Arizona. I ka wā o ka Late Triassic, ua ʻike ʻia kēia ʻāina e kahi ea wela a maloʻo, me nā muliwai a me nā loko e hāʻawi ana i nā wahi kūpono no Smilosuchus. ʻO ka loaʻa ʻana o nā mōʻalihaku Smilosuchus ma kēia mau wahi e hōʻike ana ua hoʻololi maikaʻi ʻia ia i ka wai hou a me ka honua.

ʻO ke ola a me ka hana hou ʻana o Smilosuchus

He liʻiliʻi ka ʻike e pili ana i ka pōʻaiapili ola a me nā ʻano hānau hānau o Smilosuchus. Eia nō naʻe, ma muli o ka hoʻohālikelike ʻana me nā crocodilian o kēia wā, ua waiho paha ʻo Smilosuchus i nā hua ma ka ʻāina a hōʻike i ka mālama makua i kāna mau keiki. Hōʻike ʻia nā moʻolelo mōʻalihaku o nā keiki ʻōpio ua loaʻa iā lākou nā hiʻohiʻona anatomical like me nā pākeke, e hōʻike ana ua hiki iā lākou ke ola kūʻokoʻa mai ka wā ʻōpiopio.

ʻO ka nohona a me ke kamaʻilio ʻana ma Smilosuchus

ʻAʻole ʻike nui ʻia ka ʻano pilikanaka o Smilosuchus. Eia naʻe, ʻo ka loaʻa ʻana o nā mōʻalihaku ma kahi kokoke i kekahi i kekahi e hōʻike ana ua hōʻike paha lākou i kekahi ʻano o ka hui kaiaulu a i ʻole ka hōʻuluʻulu ʻana. ʻO ke kamaʻilio ʻana ma Smilosuchus e pili ana i nā hōʻike ʻike maka, nā leo, a me nā hōʻailona olfactory. Ua ʻae kēia mau ʻano i ka poʻe e hoʻokumu i nā ʻāina, e huki i nā hoa, a pale aku i nā mea hoʻokūkū.

Moʻolelo Evolutionary a me ka hoʻokaʻawale ʻana o Smilosuchus

Aia ʻo Smilosuchus i ka pūʻulu phytosaur, ʻo ia kahi ʻāpana o ka ʻohana archosaurian nui. ʻO Phytosaurs kekahi hui like ʻole o nā mea kolo semi-aquatic i ola mai ka Late Triassic a hiki i ka wā Jurassic Early. I loko o ka pūʻulu phytosaur, ua hoʻokaʻawale ʻia ʻo Smilosuchus i ka ʻohana Smilosuchidae, a me nā ʻano like ʻole. Hiki ke ʻike ʻia ka mōʻaukala evolutionary o Smilosuchus i nā kūpuna mua o nā crocodilians a hāʻawi i nā ʻike i ka ulu ʻana o kēia mau mea kolo.

Pili i na Hoahanau Crocodile

ʻOiai ko lākou ʻano like me nā crocodiles, ʻo nā phytosaurs e like me Smilosuchus ʻaʻole nā ​​kūpuna pololei o nā crocodilian hou. Akā, hōʻike lākou i kahi moʻokūʻauhau ʻokoʻa i ulu like me ka moʻokūʻauhau crocodile. Hāʻawi nā hui ʻelua i nā hoʻololi like ʻana no ke ʻano ola wai, e like me nā kino elongated, nā ʻāwae ikaika, a me nā ʻāpana liʻiliʻi no ka ʻauʻau ʻana. Eia nō naʻe, ua hoʻokaʻawale lākou i ko lākou ala evolutionary, me ka poʻe crocodilian e lilo i mea loea no ke ʻano ola wai piha.

Hoʻopau a me ka moʻolelo mōʻalihaku o Smilosuchus

ʻO Smilosuchus, me nā phytosaurs ʻē aʻe, ua pau i ka pau ʻana o ka manawa Triassic, ma kahi o 210 miliona mau makahiki i hala. Ke hoʻopaʻapaʻa mau ʻia nei ke kumu o ko lākou hoʻopau ʻia ʻana ma waena o nā ʻepekema, akā ʻo ka hui pū ʻana o nā loli kaiapuni, ka hoʻokūkū me nā mea kolo ʻē aʻe, a me kahi hanana hoʻopau nui i pāʻani. He palena iki ka moʻolelo mōʻalihaku o Smilosuchus, me ka hapa nui o nā mea hoʻohālike. Eia nō naʻe, hāʻawi nā mōʻalihaku i loaʻa i ka ʻike waiwai e pili ana i ke anatomy, ka ʻano, a me ke kaiaola o kēia mea kolo kahiko.

Koʻikoʻi o Smilosuchus i ka hoʻomaopopo ʻana i nā kaiaola kahiko

He ʻano mōʻalihaku nui ʻo Smilosuchus no ka hoʻomaopopo ʻana i nā kaiaola kahiko o ka wā Late Triassic. ʻO kāna mau hiʻohiʻona kūʻokoʻa a me kāna mau hoʻololi e hoʻomālamalama i ka ʻokoʻa a me ka paʻakikī o nā mea ola i noho i kēia mau kaiapuni. Ma ke aʻo ʻana i ke anatomy a me ke ʻano o Smilosuchus, hiki i nā ʻepekema ke kūkulu hou i ka pūnaewele meaʻai, ka pilina predator-prey, a me ka hoʻoikaika kaiaola o kēia au kahiko. Hoʻohui ʻia, lawelawe ʻo Smilosuchus ma ke ʻano he mōʻalihaku hoʻololi koʻikoʻi, e hoʻopaʻa ana i ka āpau ma waena o nā archosaurs mua a me nā crocodilians hou, e hāʻawi ana i nā ʻike waiwai i ka mōʻaukala evolutionary o kēia mau mea kolo.
