ʻO Velociraptor kahi mea liʻiliʻi e kau nei i ka manawa Cretaceous. Ua loaʻa iā ia nā mahalo mahalo nui i ka kiʻi ʻoniʻoni "Jurassic Park". ʻO nā Velociraptors kahi i kapa ʻia nā dinosaur predatory, ʻoi aku ka kūpono o ka wehewehe. deinonychus. ^ E Ha yM. Eia nō naʻe, ʻo kēia ʻoiaiʻo ia ka "propiarized" velociraptor. ʻOi aku ka liʻiliʻi o Velociraptor ma mua o deinonychus, akā naʻe ʻaʻole liʻiliʻi, he wikiwiki a he koko.
He ʻōwili ʻōwili
Poʻo:
Pahuehu a ʻōliki a ʻōwili a ke kuʻe o ka Velociraptor, he 25 cm ka lōʻihi o kahi anana .. He ʻelima mau niho koʻikoʻi e kū ana i loko o ka waha a hoʻonohonoho i kekahi mau lālani. Hōʻalo ka puka ʻana i nā puka i loko o ka mokulele dinosaur, a ʻoi aku ka wikiwiki o ka Velocentric. ʻO ka lolo o kahi mea lapaʻau huakaʻi, no kahi dinosaur, nui. ʻO kēia paha, ʻo Velociraptor, paha kekahi o nā papa hana akamai ʻoi loa.
He kino kino Velociraptor:
He olakino lōʻihi nā manawa o ka Velociraptor, kahi e hiki ai i ka dinosaur ke hoʻomau i ka wikiwiki kūpono. Ma kēlā me kēia pā wāwae i puʻu lāʻau pohihihi, kahi i hōʻeha ʻia ai e ka Velociraptor nā mea make ma ke kanaka. E like me nā allropod, ʻehā mau wāwae wāwae o ka velociraptor ma nā wāwae ʻehā, kahi i kahakaha ʻole ʻia kekahi o ka hele. Ua hele maikaʻi ʻole ʻia nā mea mua. ʻEkolu mau manamana lima ma kēlā me kēia pā Velociraptor. ʻO ka mea mua, ʻo ka mea pōkole loa, a ʻo ka lua ka mea lōʻihi. Mālama lākou ka poʻe dinosaur i kāna mea pio. ʻO ka lūlū lōʻihi e kaupaona i mua o ke kino a kōkua i ka hoʻomaʻamaʻa ʻana i ka wikiwiki kiʻekiʻe.
ʻO ka pehu holociraptor:
I kēia lā, ke kūkākūkā nui e pili ana i ka Velociraptor pehea kona ʻano. Ua hoʻohālikelike ʻia kēia dinosaur me ka ʻili reptile ʻōmaʻomaʻo, akā i kēia mau manawa i loko nō ia i ka huluhulu e hoʻohālike ia me nā hulu hulu melemele, manuahi a me ka ʻulaʻula.
I ka paleontology o kēia wā, ʻo ka hypothesis o ka pilina o ka dromaeosaurids, ka mea iā Velociraptor a me nā manu, e ʻāpono ʻia.
I ka makahiki 2007, ua hōʻike kekahi mau paleontologists i ka ʻike ʻana i ka maʻi tubercles i loko o ka ʻōlelo kikoʻī o Velociraptor ma ka iwi ulnar, ua unuhi ʻia he mau wahi hoʻopili o nā hulu hulu. Loaʻa i nā manu o kēia mau lā nā ʻano puna wai like ʻole. Wahi a nā paleontologists, hiki i kēia loiloi ke hōʻoia iā mākou e hopena i ka plumage ka velociraptor.
ʻO ka hele ʻana aku o nā hulu ma ka Velociraptor a me kahi kokoke i nā manu e hiki ke loaʻa i nā wehewehe ʻelua e pili ana i ka ʻōiwi.
1. ʻO nā hiʻohiʻona avian maʻamau (me ka plumage) i nānā ʻia i ka dromaeosaurids e hiki ke hele mai ka hoʻoilina mai kahi kūpuna maʻamau. Wahi a kēia hypothesis, lawe mai nā dromaeosaurids a me nā manu mai kekahi o nā pūʻulu o nā coelurosaurs. Ua ʻoluʻolu ʻia kēia wehewehe ʻana.
2. ʻO Dromaeosaurids, me ka velociraptor, nā manu primitive i nalowale i ka hiki ke lele. No laila, ʻaʻole hiki i kahi velociraptor ke lele, e like me ka ostrich. ʻAʻole kaulana kēia hypothesis i waena o ka poʻe paleontologists.
OhʻEhā kahaha hou:
Ma mua o ka ʻimi ʻana i nā hua mua o ka Velociraptor, ua manaʻo ʻia ua lohi nā dinosaurs a ʻaʻole ʻano akamai loa. Eia naʻe, ua hānau ka velociraptor. Mai kahi hoʻomoʻi, hele koke ʻo ia i ka mea ʻake. ʻO ka holoholona i hoʻoulu ʻia e ka Velociraptor ʻaʻole aneane loaʻa kahi ola. ʻO ka wehe ʻana i ka mea i make, ua lele ʻo Velociraptor i kona kua a ho'āʻo hoʻi e hoʻopili i kona mau ʻāʻī i loko o ka ʻāʻī, i ʻole e ʻāʻū a i ʻole paha i ka ʻāʻī o ke koko. Ma hope o kēlā, ua hoʻopiʻi ʻo ia i nā hōʻeha kino me kāna mau leaka, ke ʻāwili ʻana i ka ʻiʻo. Ua kōkua ka huelo lōʻihi e mālama pono.
Aia kekahi ʻāpana e loaʻa i nā velociraptors, e like me kā lākou mau kamana deinonychus, i ʻimi ʻia i nā hui. Akā ʻaʻole e like me lākou, ʻaʻole i loaʻa ka hale pālahalaha o nā velociraptors. No laila, e ʻōlelo ʻo ua alualu nei ʻo Velociraptors i nā kāpena.
Hōʻiholo
| ʻO Velociraptor a me nā protoceratops kekahi o nā hihia maʻamau o ka "hunter a me ka mea pio" ma waena o nā dinosaur. I ka makahiki 1971, ʻaʻohe o ka poʻe paleontologists e hana nei ma ka Desie Gobi. Ua loaʻa lākou i nā ʻāpana o ka ʻelua mau dinosaurs - he velociraptor a me kahi protoceratops - kahi mea kahakaha a me kāna mea pio, e moe ana me kekahi. |
He ʻumi kūniha ka nui o ke koʻo i kahi ʻehā kūmole (25 cm) ka nui me ka elongated i mua o ka ʻōpū e kū pono ana i luna, piʻu ka ʻaoʻao o luna, a pihi ka lalo. Hōʻīpī ʻia kēia mau ʻaukā me nā kuleana e hoʻomālamalama i kona paona. ʻO Maxillary (ma ke kaʻe o ke kanaka ma ka ʻāpana o nā sinuses maxillary) he mau pihi a liʻiliʻi. Nā iwi intermaxillary me nā hana haʻahaʻa. Ua hala ka iwi o ka pepeiao waena. ʻO ka paia o paia o ka cranium cerebral i hui ʻia me ka iwi mua, i ʻike ʻia me ka iwi parietal. Ua like ko ka iwi kuʻekuʻe like me ka iwi ʻuʻuku ʻo Komodo monitor, ka mea i hiki ai ke hopu i ka nui o ka nui.
