Masana kimiyya a birnin Ganzhou na lardin Jiangxi da ke kudancin kasar Sin, sun gano wani abin da ya faru. Sun gano kasusuwan wani Dinosaur, wanda ke zaune a cikin gida na ƙwai.
Dinosaur, wanda aka fi sani da oviraptorosaur (oviraptor), wani ɓangare ne na ƙungiyar dinosaurs-kamar tsuntsaye waɗanda suka bunƙasa a cikin Lokacin Cretaceous (shekaru 145 zuwa 66 da suka wuce).
Balagaggun burbushin oviraptor da ƙwai masu ciki an yi kwanan watan kusan shekaru miliyan 70 da suka wuce. Wannan shi ne karo na farko da masu bincike suka gano wani dinosaur ba na ruwa ba yana hutawa a kan wani gida na ƙwai, wanda har yanzu yana ɗauke da jariri a ciki!
Burbushin da ake magana a kai shi ne wani baligi mai shekaru miliyan 70 da haihuwa oviraptorid theropod dinosaur zaune a saman wani gida na ƙwai da aka dasa. Ana iya ganin ƙwai da yawa (aƙalla uku daga cikinsu suna ɗauke da embryos) kamar yadda gaɓoɓin manya, ƙashin ƙugu, gaɓoɓin baya, da wani ɓangaren wutsiya.

Jagoran binciken, Dokta Shundong Bi na Cibiyar Nazarin Halittar Juyin Halitta, Cibiyar Nazarin Palaeontology, Jami'ar Yunnan ta Sin, da Sashen Nazarin Halittu na Jami'ar Indiana ta Pennsylvania, Amurka, ya bayyana a cikin wata sanarwa da aka rabawa manema labarai. “Dinosaurs da aka adana a cikin gidajensu ba kasafai ba ne, haka ma embryos na burbushin halittu. Wannan shi ne karo na farko da aka samu dinosaur wanda ba na ruwa ba, yana zaune a kan wani gida na ƙwai da ke adana ƴaƴan ƴaƴa, a cikin wani samfuri mai ban mamaki guda ɗaya."
Duk da cewa masana kimiyya sun hango manya oviraptors a cikin gidajensu da ƙwai a baya, wannan shine karo na farko da aka gano ƙwai a cikin ƙwai. Marubucin binciken Dokta Lamanna, masanin burbushin halittu daga Carnegie Museum of Natural History, Amurka, ya yi bayani: "Wannan nau'in ganowa, a zahiri, halayen burbushin halittu, shine mafi ƙarancin ƙarancin dinosaur. Ko da yake an sami wasu 'yan oviraptorids masu girma a kan gidajen ƙwai a da, ba a taɓa samun embryo a cikin waɗannan ƙwai ba."
Dr. Xu, wani mai bincike a cibiyar nazarin halittu da nazarin halittu da ke birnin Beijing na kasar Sin, kuma daya daga cikin mawallafin binciken, ya yi imanin cewa, wannan binciken da ba a saba gani ba ya kunshi bayanai da dama.

Ƙwai da aka yi da burbushin sun kusa ƙyanƙyashe!
Masanan kimiyya sun gano kwarangwal din wani balagaggen oviraptor da duwatsu a cikinsa. Wannan misali ne na gastroliths. "Dutsen ciki," wanda halitta ta cinye don taimaka mata narke abincinta. Har ila yau, shi ne misali na farko na gastroliths marasa gardama da aka gano a cikin wani oviraptorid, wanda masana kimiyya ke jin zai iya taimakawa wajen haskaka abinci na dinosaur.
A cikin wani matsayi ko kariya, an gano dinosaur yana tsugunne akan wani gida na aƙalla 24 burbushin ƙwai. Wannan na nuni da cewa Dinosaur ya halaka ne a lokacin da yake tarawa ko kuma yana kare jariransa.
Duk da haka, lokacin da masu binciken suka yi amfani da nazarin isotope na oxygen akan ƙwai, sun gano cewa an shuka su a yanayin zafi mai kama da tsuntsaye, suna ba da lamuni ga ka'idar cewa balagagge ya mutu yayin da yake tsiro gida.
Akalla bakwai daga cikin burbushin ƙwai har yanzu suna da embryos na oviraptorid a cikin su. Masana kimiyya sun yi imanin cewa wasu ƙwai sun kasance a gefen ƙyanƙyashe bisa ga ci gaban tushen.
