Gonkoken
Gonkoken wuxuu ahaa dinosaur yar oo af-duck leh oo ku noolaa meesha hadda loo yaqaan koonfurta Chile, meel u dhow Antarctica. Wuxuu ahaa mid dhererkiisu le'eg yahay baabuur wuxuuna isticmaali jiray boqollaal ilkihiisa si uu u calaliyo dhirta adag. Dinosaur-kan waa mid gaar ah sababtoo ah ma aha hadrosaurid dhab ah, laakiin waa qaraabo aad u qadiimi ah oo noolaa ilaa dhammaadkii xilligii dinosaurs-ka.24

Xaqiiqooyin xiiso leh
Gonkoken waa duckbill 'kala-guur ah', taas oo macnaheedu yahay inuu si dhow ula xiriiro hadrosaurids dhab ah laakiin uusan isagu mid ahayn. Awoowayaashiis waxay ka yimaadeen Waqooyiga Ameerika waxayna yimaadeen Koonfurta Ameerika goor hore ka hor duckbills-ka horumarsan.2
Magaca Gonkoken wuxuu ka yimid luqadda Aónik’enk, oo ay ku hadlaan dadka asaliga ah ee gobolka. 'Gon' macnaheedu waa 'la mid ah' iyo 'koken' macnaheedu waa 'duck duurjoog ah ama swan'.21
Lafaha Gonkoken waxaa laga helay meel ay ku jiraan ugu yaraan saddex qof. Goobta weli waa la qodayaa waxaana laga yaabaa inay ku jiraan lafo kale oo badan.2
Gonkoken wuxuu noolaa qiyaastii 71.7 ilaa 70.5 milyan oo sano ka hor, xilligii hore ee Maastrichtian ee Late Cretaceous. Tani waxay ahayd dhowr milyan oo sano ka hor intaanu dhicin asteroid-kii soo afjaray xilligii dinosaurs-ka.2
Si ka duwan hadrosaurids dhab ah, Gonkoken wuxuu lahaa wax ka yar 30 meelood oo ilko ah daankiisa hoose, safafka ilkihiisuna kama gudbin qaybta coronoid process.2
Gonkoken waa dinosaur-kii ugu horreeyay ee af-duck leh oo laga sharraxay gobolka subantarctic. Helitaankiisu waxay soo jeedinaysaa in qaar ka mid ah lafaha hadrosaurid ee laga helay Antarctica ay dhab ahaantii ka tirsan yihiin duckbills aan hadrosaurid ahayn sida Gonkoken.2
Su'aalaha ugu badan ee ku saabsan Gonkoken
?Intee ayuu weynaa Gonkoken?
Gonkoken wuxuu ahaa dinosaur yar oo af-duck leh, qiyaastii 4 m (13 feet) dherer ahaan. Taasi waa qiyaastii dhererka baabuur yar.12
?Goormuu noolaa Gonkoken?
Gonkoken wuxuu noolaa qiyaastii 71.7 ilaa 70.5 milyan oo sano ka hor, xilligii hore ee Maastrichtian ee Cretaceous-ka dambe. Taasi waxay ahayd dhawr milyan oo sano ka hor intaanu asteroid-ku dhicin.12
Burinta khuraafaadka
Khuraafaad: Dhammaan dinosaurs-ka af-duck-ka leh waa hadrosaurids (duckbills dhab ah).
Runta: Gonkoken waa dinosaur af-duck leh laakiin ma aha hadrosaurid. Wuxuu ka tirsan yahay qoys aad u qadiimi ah oo la noolaa duckbills dhab ah oo ku noolaa koonfurta fog.2

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu waxay ku doodayaan in dhammaan lafaha hadrosaurid ee laga helay Antarctica iyo gobollada koonfurta ay dhab ahaantii ka tirsan yihiin dinosaurs-ka af-duck-ka leh ee aan hadrosaurid ahayn sida Gonkoken, halkii ay ka ahaan lahaayeen hadrosaurids dhab ah.2
