Cerebavis
I-Cerebavis kwakuyinyoni eyayiphila eminyakeni engaba ngu-95 yezigidi edlule, ngesikhathi sama-dinosaur. Yayinobuchopho obubukeka busezingeni eliphezulu, cishe njengobuchopho bezinyoni ozibona namuhla. Ugebhezi lwayo lwatholakala e-Russia futhi ososayensi basebenzisa izithombe ezikhethekile ukuze bafunde ukwakheka kobuchopho bayo.2

Amaqiniso amnandi
I-Cerebavis yaziwa ngogebhezi oluyingxenye kuphela, olwalucatshangwa ekuqaleni ukuthi luwubuchopho obuphenduke amatshe.1
Ososayensi manje bayazi ukuthi lesi sibonelo empeleni singugebhezi, hhayi ubuchopho, futhi basebenzisa izithombe ze-CT ukuze babone ukwakheka kobuchopho ngaphakathi.2
I-Cerebavis yayingenazo izimbobo eziseceleni kwamehlo egebhezini. Lesi yisici sezinyoni zohlobo lwe-ornithurine, hhayi i-enantiornithines.2
Ubuchopho be-Cerebavis babufana kakhulu nobuchopho benyoni yanamuhla kunezinyoni zakudala ezifana ne-Archaeopteryx.2
I-Cerebavis yayingenayo i-wulst, ingxenye ekhethekile yobuchopho esiza izinyoni zanamuhla ngokubona nokuthinta. Lesi sici sasingakaveli eminyakeni eyizigidi ezingama-93 edlule.2
Amathambo egebhezi le-Cerebavis ayebambene kakhulu, okuyisibonakaliso sokuzivumelanisa nokundiza okuthuthukile, okufana nezinyoni zanamuhla ezindizayo.2
Buza u-Rex ngo-Cerebavis
Rex uphendula imibuzo mayelana naleli khasi kuphela. Imibuzo engu-10 ngenyanga.
Rex uyi-AI futhi angenza amaphutha. Usebenza kumaseva ase-EU futhi imibuzo ayilokothi ilondolozwe. Ungalokothi uthayiphe igama lakho noma ezinye izinto zakho.
Umchithi wezinganekwane
Inganekwane: I-Cerebavis kwakuyi-dinosaur enobuchopho obubukeka bungajwayelekile futhi obuhlukile kunanoma yisiphi esinye isilwane.
Iqiniso: Ososayensi ekuqaleni babecabanga ukuthi ubuchopho babungajwayelekile, kodwa izithombe ezintsha ze-CT zibonisa ukuthi empeleni babufana kakhulu nobuchopho bezinyoni zanamuhla.2

Yonke imininingwane ekuleli khasi inenombolo ekhomba umthombo wayo. Uma kukhona esikwenze kabi, siyaxolisa, singabalandeli bama-dino, hhayi iphephabhuku lesayensi. Sitshele ku-[email protected] futhi sizokulungisa.
Rex ulambile! I-Dino Wiki iphrojekthi kababa wendodana yakhe ethanda ama-dino, imahhala ngaphandle kwezikhangiso nezilandeleli. Abantu abadala bangaphakela u-Rex ukudla okulula ukuze basize ukuyigcina iku-inthanethi.Phakela u-Rex
