Ukhakhayi lwenyoni ebelugcinwe ngendlela exakile ku-amber kusukela eminyakeni eyizigidi ezingama-99 eyedlule, olutholakala eBurma, yi-dinosaur encane kunazo zonke ezaziwa kuze kube manje.
Isifanekiso, esibizwa ngokuthi “Oculudentavis khaungraae“, Wavaleleka esiqeshini senhlaka esasiphakathi nesikhathi seMesozoic. Lokhu kusho ukuthi phakathi kweminyaka eyizigidi ezingama-251 edlule neminyaka eyizigidi ezingama-65 edlule. U-Lida Xing wase China University of Geosciences uqale wahlola lesi siqephu se-amber ekuqaleni kuka-2020.
Ukhakhayi lwalesi dinosaur lwalungamamilimitha ayisikhombisa kuphela ubude
Lokhu ngosayizi ofana ne- zunzuncito, okuyizinhlobo ezincane kakhulu ze-hummingbird. Ngakho-ke, kungayenza ibe idayinaso encane kunazo zonke ezaziwayo, ngokusho kwalo magazini Nature.
“Njengazo zonke izilwane ezibhajwe enhlaka, ivikeleke kahle kakhulu. Sinomuzwa wokuthi lishonile izolo, zonke izicubu zalo ezithambile zigcinwe kuleli windi elincane lasendulo, ” kuphawule umbhali oholayo wesifundo, uJingmai O'Connor. Uyingxenye ye-Institute of Vertebrate Paleontology and Paleontropology eBeijing.
Ugebhezi oluphrofayili luphethwe yisokhethi enkulu yamehlo, kusikisela ukuthi bekukhona iso elibheke eceleni, elifana nalesi sibankwa. Ngosizo lwe-scanner, abacwaningi baveza umhlathi onamazinyo ayikhulu akhombe ngaphakathi komlomo.
Kwakungumzingeli omncane
“Alifani nanoma yiluphi uhlobo lwezinto eziphilayo olukhona namuhla, ngakho-ke kumele sibe nomcabango wokuqonda ukuthi kusho ukuthini ukwakheka kwalo. Kodwa-ke, ukhakhayi lwayo oluthambile, amazinyo amaningi namehlo amakhulu kusikisela ukuthi naphezu kobukhulu balo mhlawumbe kwakuyisilwane esidla izinambuzane, ” ngokusho kwe-paleontologist.
I-vertebrate yahlala nama-dinosaurs anentamo ende nezilwane ezinwabuzelayo ezinkulu ezindizayo ezinjenge-pterosaurs, esikhathini sezilwane eziningi.
Kwakuyingxenye ye-microfauna okwakungalondolozwa i-amber kuphela. Ngaphandle kwale resin yezinsalela, “Besingazi lutho ngalezi zinto ezincane eziphilayo, okunzima kakhulu ukuzithola kunezinkulu,” Kusho lososayensi.
Lapho sicabanga ngama-dinosaurs, sicabanga ngamathambo amakhulu kodwa njengamanje i-paleontology isiguqulwa ngokuphelele ngenxa yokutholakala kwezinsalela ezigcinwe ngale ndlela. Kufanele kube nezingcezwana ze-DNA ezigcinwe ngaphakathi, lapho singathola khona ulwazi oluyigugu lokuthi umhlaba wangaphambi komlando wake wavela kanjani.
