Lub ntiaj teb ntawm paleontology yog ib txwm tag nrho ntawm surprises, thiab nws tsis yog txhua txhua hnub uas nrhiav tau ib hom tshiab ntawm dinosaur. Thaum Lub Ob Hlis 6, 2023, cov kws tshawb fawb tau tshaj tawm tias lawv tau pom ib hom tshiab ntawm dinosaur uas txuas nrog rau Tyrannosaurus rex.
Thanatotheristes degrootorum, uas txhais ua "Reaper of Death" hauv Greek, kwv yees tias yog tus tswv cuab qub tshaj plaws ntawm tsev neeg T-Rex uas tau pom nyob rau sab qaum teb North America txog tam sim no. Nws yuav tau mus txog qhov ntev ntawm ib ncig ntawm yim meters (26 ko taw) hauv nws cov neeg laus.
Darla Zelenitsky, tus pab xibfwb ntawm Dinosaur Palaeobiology ntawm Canada's University of Calgary tau hais tias "Peb tau xaiv lub npe uas suav nrog qhov tyrannosaur no yog tib lub npe loj apex predator ntawm nws lub sijhawm hauv Canada, tus sau ntawm kev tuag," said Darla Zelenitsky, tus pab xibfwb ntawm Dinosaur Palaeobiology ntawm Canada's University of Calgary. "Lub npe menyuam yaus tau los ua Thanatos," nws hais rau AFP.
Whereas T-Rex - nto moo tshaj plaws ntawm txhua hom dinosaur, immortalized nyob rau hauv Steven Spielberg's 1993 epic Jurassic Park - stalked nws cov tsiaj nyob ib ncig ntawm 66 lab xyoo dhau los, Thanatos hnub rov qab tsawg kawg yog 79 lab xyoo, pab neeg tau hais. Cov qauv no tau tshawb pom los ntawm Jared Voris, tus tub kawm PhD ntawm Calgary; thiab nws yog thawj hom tyrannosaur tshiab pom hauv 50 xyoo hauv Canada.
Zelenitsky, tus kws sau ntawv ntawm txoj kev tshawb fawb uas tau tshwm sim hauv phau ntawv Journal Cretaceous Research tau hais tias "Muaj ob peb hom tyrannosaurids, kuj hais lus." "Vim qhov xwm txheej ntawm cov khoom noj khoom haus no cov tsiaj apex loj no tsis tshua muaj piv rau herbivorous lossis cog-nosaurs."
Txoj kev tshawb nrhiav pom tias Thanatos muaj qhov ntev, qhov tob tob, zoo ib yam li cov tyrannosaurs qub qub uas nyob rau yav qab teb Tebchaws Meskas. Cov kws tshawb fawb tau qhia tias qhov sib txawv ntawm tyrannosaur pob txha taub hau ntawm cov cheeb tsam tuaj yeem ua rau qhov sib txawv ntawm kev noj zaub mov, thiab nyob ntawm cov khoom noj muaj nyob rau lub sijhawm.
Qhov kev tshawb pom ntawm hom tshiab ntawm dinosaur yog lub sijhawm zoo siab rau txhua tus neeg nyiam paleontology. Tus Reaper of Death, tus kwv tij txheeb ze tshiab ntawm Tyrannosaurus rex, yog qhov txaus nyiam ntxiv rau tsev neeg tsob ntoo ntawm dinosaurs.

Peb cia siab tias koj tau txaus siab kawm txog qhov kev tshawb pom zoo kawg no thiab nws haum rau hauv daim duab loj ntawm dinosaur evolution. Khaws ib lub qhov muag tawm rau kev hloov tshiab ntxiv thiab kev tshawb fawb ntawm cov tsiaj ntxim nyiam no, thiab leej twg paub tias lwm yam kev xav tsis thoob ntiaj teb ntawm paleontology yuav muaj nyob rau hauv khw rau peb yav tom ntej!
