Ua ʻike nā kānaka ʻepekema ma ke kūlanakauhale ʻo Ganzhou, ka ʻaoʻao hema o Jiangxi o Kina, i kahi ʻike holomua. Ua ʻike lākou i nā iwi o kahi dinosaur, e noho ana ma luna o kona pūnana hua manu.
ʻO ka dinosaur, i kapa ʻia ʻo ka oviraptorosaur (oviraptor), he ʻāpana ia o ka hui o nā dinosaur theropod e like me nā manu i ulu i ka wā Cretaceous (145 a 66 miliona mau makahiki i hala).
Ua helu ʻia nā mōʻalihaku oviraptor makua a me nā hua embryonic ma kahi o 70 miliona mau makahiki i hala. ʻO kēia ka manawa mua i ʻike ai nā mea noiʻi i kahi dinosaur non-avian e waiho ana ma luna o kahi pūnana hua manu, aia nō ka pēpē i loko!
ʻO ka mōʻalihaku i nīnau ʻia, he 70 miliona mau makahiki makua oviraptorid theropod dinosaur e noho ana ma luna o ka pūnana o kāna mau hua manu. ʻIke ʻia nā hua he nui (ma kahi o ʻekolu o ia mau embryos) e like me nā lima o ke kanaka makua, ke pelvis, nā lālā hope, a me kahi hapa o ka huelo. (Ke Kulanui ʻo Indiana o Pennsylvania ʻo Shandong Bi)
He aha ka ʻōlelo a ka poʻe ʻepekema e pili ana i ka ʻike?
ʻO ka mea kākau alakaʻi o ke aʻo ʻana, ʻo Kauka Shundong Bi o ka Center for Vertebrate Evolutionary Biology, Institute of Palaeontology, Yunnan University, Kina, a me ke Keʻena Biology, Indiana University of Pennsylvania, USA, i ʻōlelo ʻia i loko o kahi hoʻolaha paʻi, "He mea kakaikahi nā dinosaur i mālama ʻia ma ko lākou pūnana, a pēlā pū nā embryos fossil. ʻO kēia ka manawa mua i loaʻa ai kahi dinosaur non-avian, e noho ana ma luna o kahi pūnana hua e mālama ai i nā embryos, i loko o kahi hiʻohiʻona kupaianaha hoʻokahi.
ʻOiai ua ʻike mua ka poʻe ʻepekema i nā oviraptors makua ma ko lākou pūnana me nā hua ma mua, ʻo kēia ka manawa mua i ʻike ʻia nā embryos i loko o nā hua. Ua wehewehe ʻo Dr. Lamanna, ka mea kākau hoʻopaʻa haʻawina, he paleontologist mai ka Carnegie Museum of Natural History, USA: "ʻO kēia ʻano ʻike, ʻo ia hoʻi, ka hana fossilized, ʻo ia ka mea laʻa loa o nā mea liʻiliʻi i nā dinosaurs. ʻOiai ua loaʻa kekahi mau oviraptorids makua ma nā pūnana o kā lākou mau hua ma mua, ʻaʻohe embryos i loaʻa i loko o ia mau hua.
ʻO Kauka Xu, he mea noiʻi ma ka Institute of Vertebrate Paleontology and Paleoanthropology ma Beijing, Kina, a me kekahi o nā mea kākau o ka noiʻi, manaʻoʻiʻo ʻo kēia ʻike maʻamau ka nui o ka ʻike, "He mea kupaianaha ke noʻonoʻo i ka nui o ka ʻike olaola i hopu ʻia i loko o kēia mōʻalihaku hoʻokahi." Wahi a Kauka Xu, "E aʻo ana mākou mai kēia hiʻohiʻona no nā makahiki he nui e hiki mai ana."
ʻO nā hua fossilized ua kokoke e hāʻule!
Ua ʻike ka poʻe ʻepekema i ka iwi oviraptor makua me nā pōhaku i loko o kona ʻōpū. He laʻana kēia o ka gastroliths, "pōhaku ʻōpū," ka mea i ʻai ʻia e ka mea ola e kōkua iā ia e ʻeli i kāna ʻai. ʻO ia ka manawa mua o nā gastroliths i ʻike ʻole ʻia i loko o kahi oviraptorid, i manaʻo ʻia e nā ʻepekema e kōkua i ka hoʻomālamalama ʻana i ka meaʻai o nā dinosaurs.
I loko o kahi ʻano hoʻohalahala a pale paha, ua ʻike ʻia ka dinosaur e kūlou ana ma luna o kahi pūnana o nā hua fossilized he 24 a i ʻole. Hōʻike kēia i ka make ʻana o ka dinosaur i ka wā e noʻonoʻo ana a mālama paha i kāna mau pēpē.
Eia nō naʻe, i ka hoʻohana ʻana o ka poʻe noiʻi i ka loiloi isotope oxygen ma luna o nā hua, ua ʻike lākou ua hoʻomoʻi ʻia lākou i nā wela kiʻekiʻe e like me nā manu, e hōʻoiaʻiʻo ana i ka manaʻo ua make ke kanaka makua i ka wā e hoʻomoe ana i kona pūnana.
Ma kahi o ʻehiku o nā hua fossilized i loaʻa nā embryos oviraptorid ʻaʻole i paʻi ʻia i loko o lākou. Manaʻo ka poʻe ʻepekema aia kekahi o nā hua ma ka lihi o ka hāʻina ma muli o ka hoʻomohala ʻana o nā kumu. Wahi a Kauka Lamanna, "He makua mālama kēia dinosaur i hāʻawi i kona ola i ka wā e hānai ana i kāna ʻōpio."
