Ugrunaaluk
IUgrunaaluk yayiyi-dinosaur enomlomo ofana nowedada eyayihlala e-Arctic yasendulo, lapho kwakubanda futhi kumnyama ingxenye yonyaka. Yayinomlomo omude, oyisicaba namakhulu amazinyo okuhlafuna izitshalo eziqinile. Le dinosaur ikhethekile ngoba ikhombisa ukuthi amanye ama-dinosaur ayekwazi ukusinda ezindaweni ezibandayo.51

Amaqiniso amnandi
IUgrunaaluk yaphila e-Arctic eminyakeni eyizigidi eziyi-69 edlule, lapho isimo sezulu sasiqanda kakhulu kunanamuhla, namazinga okushisa aphakathi nendawo angaba ngu-5 kuya ku-6°C.1
Iningi lezinsalela ze-Ugrunaaluk ezitholiwe zivela ezilwaneni ezisencane, hhayi ezikhulile ngokuphelele. Ososayensi bacabanga ukuthi umhlambi wonke wamathole kungenzeka washona ndawonye ngenxa yezikhukhula.1
Igama lalo livela olimini lwesi-Iñupiaq lwase-Alaska. Ugruŋnaq kusho isilwane esidla utshani esinamazinyo okugaya, kanti -aluk kusho okudala, ngakho i-Ugrunaaluk isho 'isidli-tshani sasendulo'.1
I-Ugrunaaluk yayihlobene eduze ne-Edmontosaurus, kodwa ososayensi bathola umehluko owanele emathanjeni ogebhezi lwayo ukuze bayinikeze igama layo.1
Indawo yamathambo i-Liscomb lapho kwatholakala khona i-Ugrunaaluk inezinkulungwane zamathambo, ikakhulukazi alolu hlobo lwedinosaur, kanye namazinyo ambalwa avela kuma-tyrannosaur namanye ama-dinosaur amancane.1
Ngesikhathi se-Ugrunaaluk, i-Arctic yayinamahlathi ase-polar anezitshalo eziqhakazayo phansi, kanti izinsuku zaziba mnyama izinyanga eziningi ebusika.1
Imibuzo ebuzwa kakhulu mayelana no-Ugrunaaluk
?I-Ugrunaaluk yayingakanani?
I-Ugrunaaluk yayingamamitha ayi-7.6 kuya kwayi-9.1 ubude futhi yayimile ngamamitha ayi-1.8 kuya kwayi-2.1 ukuphakama okhalweni.4
?I-Ugrunaaluk yayidla ini?
Yayidla izitshalo, inomlomo oyisicaba namazinyo amaningi okuhlafuna izitshalo eziqinile. Umhlathi wayo wawunamazinyo okungenani ayi-1,000 anezindawo ezingamahlakahlaka ezazikahle kakhulu ekugayeni izitshalo.4
?Ingabe i-Ugrunaaluk yayihlala e-Arctic?
Yebo, i-Ugrunaaluk yayihlala e-Arctic yasendulo, ngaphezu kwe-Arctic Circle, eminyakeni eyizigidi ezingama-69 edlule. Yayibekezelela ubusika obubandayo nobumnyama, namazinga okushisa aphakathi nendawo acishe abe ngu-5 kuya ku-6°C.41
?Ingabe i-Ugrunaaluk yayiyidinosaur enomlomo onjengowadada?
Yebo, i-Ugrunaaluk yayiyingxenye yeqembu lama-hadrosaur, ama-dinosaur anomlomo onjengowadada. Yayinomlomo omude, oyisicaba namazinyo amaningi okuhlafuna izitshalo.4
?Kungani i-Ugrunaaluk ikhethekile?
I-Ugrunaaluk ikhethekile ngoba ikhombisa ukuthi amanye ama-dinosaur ayekwazi ukusinda ezindaweni ezibandayo kakhulu. Yayihlala ngaphezu kwe-Arctic Circle, ibekezelela izinyanga zobumnyama nokubanda.4
?I-Ugrunaaluk yayinamazinyo amangaki?
I-Ugrunaaluk yayinamazinyo okungenani ayi-1,000 emhlathini wayo, anezindawo ezingamahlakahlaka ezazikahle kakhulu ekugayeni izitshalo.4
?I-Ugrunaaluk yayihlala nini?
I-Ugrunaaluk yayihlala eminyakeni eyizigidi ezingama-69 edlule, ngesikhathi se-Late Cretaceous, e-Arctic yasendulo.4
?Ingabe i-Ugrunaaluk ihlobene ne-Edmontosaurus?
Yebo, i-Ugrunaaluk ihlobene eduze ne-Edmontosaurus, kodwa ososayensi bathola umehluko owanele emathanjeni ogebhezi lwayo ukuze bayinikeze igama layo.1
?I-Ugrunaaluk yatholakala kuphi?
Izinsalela ze-Ugrunaaluk zatholakala endaweni yamathambo i-Liscomb e-Prince Creek Formation enyakatho ye-Alaska, eceleni komfula i-Colville.1
Umchithi wezinganekwane
Inganekwane: IUgrunaaluk iyisilwane esisencane nje se-Edmontosaurus hhayi i-dinosaur ehlukile yangempela.
Iqiniso: Ososayensi bakhombisa ukuthi iUgrunaaluk inezici eziyingqayizivele zikagebhezi ezenza ukuba ibe yinhlobo ehlukile, ngisho nalapho kucatshangelwa umehluko weminyaka.1
