Psephochelys
Psephochelys wuxuu ahaa xamaarato badda ku nool oo u eg qoolley, kaas oo noolaa xilligii Late Triassic, qiyaastii 233 ilaa 227 milyan oo sano ka hor. Wuxuu dhabarka ku lahaa qolof ka samaysan taargooyin lafo yar oo badan, laakiin caloosha kuma lahayn qolof, kaliya lafo dabacsan. Wuxuu ku dabaalan jiray badaha diirran meesha ay maanta tahay Shiinaha.12

Xaqiiqooyin xiiso leh
Psephochelys waxaa laga yaqaanaa hal nooc oo kaliya, Psephochelys polyosteoderma, fosilkii ugu horreeyayna wuxuu ahaa lafo qayb ahaan la helay oo laga helay Falong Formation ee Shiinaha.1
Si ka duwan qoolleyda, Psephochelys ma lahayn qolof adag oo caloosha ah. Taa beddelkeeda, wuxuu lahaa lafo u eg feeraha iyo taargooyin lafo yar oo si dabacsan isugu xiran.1
Muunad da'yar ayaa muujinaysa in qolofka Psephochelys uu ku koray isku-darka taargooyin yaryar, laga bilaabo bartamaha iyo geesaha, taas oo la mid ah sida qolofka qoolleydu u koro.3
Psephochelys wuxuu ka tirsanaa koox loo yaqaan placodonts, kuwaas oo ahaa xamaarato badda ku nool oo u ekaa qoolley laakiin aan si dhow ula xiriirin.1
Magaca Psephochelys macnihiisu waa 'qoolley dhagaxyo leh' sababtoo ah qolofkiisu wuxuu ka samaysan yahay taargooyin lafo yar oo u eg dhagaxyo.1
Psephochelys wuxuu noolaa xilligii Carnian ee Late Triassic, inta u dhaxaysa qiyaastii 233 iyo 227 milyan oo sano ka hor.2

- Psephochelys waxaa magacaabay cilmi-baare Shiineys ah Chun Li iyo cilmi-baare Swiss ah Olivier Rieppel sanadkii 2002, iyadoo lagu saleynayo hal lafo oo qayb ahaan la helay oo laga helay Guizhou, Shiinaha.12
- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli waxay ku doodayaan sida dhabta ah ee Psephochelys uu ula xiriiro placodonts-ka kale, iyo in qolofkiisu uu u koray si tilmaamaysa awoowe guud oo ay la wadaagaan qoolleyda.3
