Dinosaur wazaka 110 miliyoni wosungidwa bwino kwambiri wopezeka mwangozi ndi ogwira ntchito ku migodi ku Canada

Mabwinjawo akuwoneka ngati anali ndi masabata ochepa okha ngakhale kuti dinosaur anafa zaka zoposa 110 miliyoni zapitazo.
Dinosaur wazaka 110 miliyoni wosungidwa bwino kwambiri wopezeka mwangozi ndi ogwira ntchito ku migodi ku Canada 1

Zaka zingapo zapitazo, ku Western Canada, ntchito ya migodi inachititsa kuti pakhale chinthu chimodzi chofunika kwambiri padziko lonse chimene sichinachitikepo posachedwapa. Gulu la anthu ogwira ntchito m'migodi mwangozi linakumana ndi sayansi ya nyama ya dinosaur yomwe sinayambe yawonapo.

Borealopelta (kutanthauza "Northern shield") ndi mtundu wa nodosaurid ankylosaur wochokera ku Early Cretaceous of Alberta, Canada. Lili ndi mtundu umodzi, B. markmitchelli, wotchulidwa mu 2017 ndi Caleb Brown ndi anzake ochokera ku chitsanzo chosungidwa bwino chotchedwa Suncor nodosaur.

Nodosaur, ndi herbivore yomwe inali yaitali mamita 18 ndi pafupifupi mapaundi 3,000, inapezedwa mu 2011 ndi gulu lomwe likugwira ntchito makilomita 17 kumpoto kwa Alberta, Canada pa ntchito ya migodi. Izi ndi zochititsa chidwi zomwe zapezedwa chifukwa zotsalira za dinosaur zasungidwa bwino; kuchokera kwa iwo, tingaphunzire zambiri za moyo ndi imfa ya dinosaur.

Asayansi amati mabwinjawo akuwoneka ngati anali ndi milungu yochepa chabe ngakhale kuti dinosaur anafa zaka zoposa 110 miliyoni zapitazo. Izi ndichifukwa cha momwe zinthu zilili bwino zomwe zidasungidwa.

Dinosaur - Borealopelta (kutanthauza "Northern shield") ndi mtundu wa nodosaur omwe anakhalako nthawi ya Cretaceous - anali mmodzi mwa ambiri omwe anatha kumapeto kwake chifukwa cha kusesedwa ndi madzi osefukira mumtsinje pamene inkalowa. nyanja.

Zida zokhuthala zomwe zimazungulira chigobacho ndizomwe zimapangitsa kuti zikhale bwino. Zimakutidwa kuchokera kumutu mpaka kumapazi mu mbale zonga matailosi ndipo, ndithudi, patina wotuwa wa zikopa zotsalira.

Shawn Funk, yemwe anali kugwiritsa ntchito makina olemera mu Millennium Mine, anapeza zodabwitsa pamene chofukula chake chinagunda chinthu cholimba. Zomwe zinkawoneka ngati miyala ya walnuts zinali zotsalira za nodosaur wazaka 110 miliyoni. Nyama yochititsa chidwiyi inali yokwanira kuti theka lakutsogolo - kuyambira pamphuno mpaka m'chiuno - libwezeretsedwe.

Michael Greshko wa bungwe la National Geographic anati: “Mabwinja a dinosaur amene ang’ambika n’ngodabwitsa kuwaona.

“Zotsalira za zikopa zotsalira za zikopa zimaphimbabe zida zankhondo zomwe zili m'mutu wa nyamayo. Phazi lake lakumanja lili m’mbali mwake, ndipo manambala ake asanu amatambasulira m’mwamba. Nditha kuwerenga mamba pachokhacho,” akulemba motero Greshko.

Chifukwa cha kuikidwa m'manda mofulumira, dinosaur amawoneka ngati momwe amachitira zaka mamiliyoni ambiri zapitazo. Malinga ndi akatswiri ofufuza zinthu zakale, mfundo yakuti minyewa yake sinawole koma inasanduka zinthu zakale zakufa, n’njosowa kwambiri.

Mosiyana ndi wachibale wake wapamtima Ankylosauridae, ma nodosaurs analibe zibonga zogawikana. M’malomwake, inkavala zida zodzitetezera kuti zisawonongeke. Dinosaur wautali wa mamita 18, amene anakhalako m’nyengo ya Cretaceous, akanatha kuonedwa ngati chipembere cha nthaŵi yake.
