“King Nos?”Qhov ntawd yog lub npe muab rau ib tug nyuam qhuav nrhiav tau hadrosaur nrog lub npe scientific Rhinorex condrupus.Nws tau tshawb pom cov nroj tsuag ntawm Cretaceous lig txog 75 lab xyoo dhau los.
Tsis zoo li lwm cov hadrosaurs, Rhinorex tsis muaj pob txha lossis nqaij tawv ntawm nws lub taub hau.Hloov chaw, nws ntaus lub qhov ntswg loj.Tsis tas li ntawd, nws tau pom tsis nyob rau hauv lub pob zeb zoo li lwm cov hadrosaurs tab sis ntawm Brigham Young University ntawm lub txee hauv chav tom qab.
Tau ntau xyoo lawm, cov neeg yos hav zoov dinosaur fossil mus txog lawv cov dej num nrog xaiv thiab duav thiab qee zaum dynamite.Lawv chiseled thiab blasted pov tseg tons ntawm pob zeb txhua lub caij ntuj sov, nrhiav cov pob txha.Tsev kawm ntawv lub chaw soj nstuam thiab cov tsev khaws puav pheej keeb kwm uas muaj ib feem lossis ua tiav cov pob txha dinosaur.Ib feem tseem ceeb ntawm cov pob txha, txawm li cas los xij, tseem nyob hauv cov crate thiab plaster cam khwb cia squirreled nyob rau hauv cia bins.Lawv tsis tau muaj sijhawm los qhia lawv cov dab neeg.
Qhov xwm txheej tam sim no tau hloov pauv lawm.Qee cov paleontologists piav qhia txog kev tshawb fawb dinosaur raws li kev hloov kho thib ob.Qhov lawv txhais tau li cas yog tias cov txheej txheem tshiab tau raug coj los ua kom nkag siab tob rau hauv lub neej thiab lub sijhawm ntawm dinosaurs.
Ib qho ntawm cov txheej txheem tshiab no tsuas yog saib qhov uas twb tau pom lawm, ib yam li Rhinorex.
Nyob rau xyoo 1990, cov pob txha ntawm Rhinorex tau muab tso rau hauv Brigham Young University.Thaum lub sij hawm, paleontologists tsom rau ntawm daim tawv nqaij impressions pom nyob rau hauv cov pob txha pob txha, tawm hauv me ntsis sij hawm rau fossilized pob txha taub hau tseem nyob rau hauv lub pob zeb.Tom qab ntawd, ob tus kws tshawb fawb tom qab tau txiav txim siab saib lub pob txha taub hau dinosaur.Ob xyoos tom qab, Rhinorex tau tshawb pom.Paleontologists tau tso lub teeb tshiab rau lawv txoj haujlwm.
Rhinorex tau raug khawb los ntawm ib cheeb tsam ntawm Utah hu ua Neslen site.Geologists muaj cov duab meej zoo nkauj ntawm Neslen qhov chaw ib puag ncig ntev dhau los.Nws yog ib qho chaw nyob estuarine, ib qho av qis uas cov dej tshiab thiab ntsev sib xyaw nyob ze ntawm ntug dej hiav txwv ntawm lub hiav txwv thaum ub.Tab sis sab hauv av, 200 mais deb, thaj av txawv heev.Lwm yam hadrosaurs, hom crested, tau raug khawb hauv av.Vim hais tias yav dhau los palenontologists tsis tau tshuaj xyuas tag nrho Neslen skeleton, lawv xav tias nws yog ib tug crested hadrosaur.Raws li qhov tshwm sim ntawm qhov kev xav, qhov kev txiav txim siab tau kos tias tag nrho cov kab mob crested hadrosaurs tuaj yeem siv cov peev txheej hauv av thiab estuarine sib npaug.Nws tsis yog txog thaum palenotologists rov tshuaj xyuas nws tias nws yog Rhinorex tiag.
Zoo li daim duab puzzle poob rau hauv qhov chaw, nrhiav pom tias Rhinorex yog ib hom tshiab ntawm Cretaceous lub neej.Nrhiav "King Nose" tau pom tias muaj ntau hom tsiaj ntawm hadrosaurs yoog thiab hloov zuj zus mus rau qhov sib txawv ecological niches.
Los ntawm tsuas yog saib ze ze ntawm cov pob txha hauv cov khib nyiab pov tseg, paleontologists tab tom nrhiav cov ceg tshiab ntawm tsob ntoo dinosaur ntawm lub neej.
