I-shark yefosili ithiywe ngePochita evela kwi-Chainsaw Man

  • Iintlobo ezintsha ze-sawshark ebizwa ngokuba yi-Pochitaserra patriciacanalae, iphefumlelwe yi-Pochita kwaye inikezelwe kuPatricia Canales.
  • Ukufumana kwi-Bahía Inglesa Formation (Atacama), ukusuka kwi-Late Miocene, echazwe kumazinyo amancinci alithoba.
  • Uphononongo luhlalutye ngaphezu kwe-300 kg yentlenga kwaye ichonge i-241 microfossils ukusuka kwi-19 taxa, kunye neerekhodi eziphambili zokuqala zoMzantsi Melika kunye ne-Southern Hemisphere.
  • I-ray Dasyatis manuelcamposi nayo ichazwe; uphando lwapapashwa kuPhepha kwiPalaeontology.

I-fossil shark iphefumlelwe nguPochita

I-paleontology kunye nenkcubeko edumileyo iye yadibana ngokungalindelekanga: kufunyenwe uhlobo olutsha lwe-sawshark. ebizwa ngokuba yimbeko yePochita, umlinganiswa ovela kwimanga kunye ne-anime Chainsaw Man, emva kokufunyanwa emantla eChile.

Umsebenzi, opapashwe kwijenali yaseBritane Amaphepha kwiPalaeontology, amaxwebhu ahlala e Kade iMiocene kwi-Bahía Inglesa Formation (Ummandla we-Atacama), kunye nobudala obuqikelelwayo malunga nezigidi ezisixhenxe zeminyaka kunye nexabiso elimangalisayo lesayensi.

Ukrebe wefosili onegama elifana nemanga

Ukufunyanwa kwePaleontological e-Bahía Inglesa

Uhlobo luthiweywe igama Pochitaserra patriciacanalaeIgama lidibanisa inkokhelo kwi-paleontologist yaseChile uPatricia Canales ngokubhekisele kwiPochita. Iqela lichonge irhafu ukusuka amazinyo asithoba e-microscopic, ngokwaneleyo ukuseka uhlobo olutsha olutshabaleleyo kunye neentlobo.

Isiteketiso esidityaniswe neChainsaw Man asinto yanto yanto nje: i-anatomy ye-sawshark, ene ubuso obude namazinyo efana ne-chainsaw, ihambelana ne-iconography yomlinganiswa, izisa ukufunyanwa kufutshane nabaphulaphuli abangabalulekanga.

Lwaqhutywa njani uphando

Eli phulo ligxile kwintlenga evela kwicandelo le-Econssa (indawo yaseCaldera). Phantsi kolwalathiso lwe UGqr. Jaime Villafaña (UCSC)Abaphandi bacubungula ngaphezulu kwe-300 yeekhilogram zezinto zokubuyisela i-microfossils ye-elasmobranchs.

Ubalo lokugqibela lubonisiwe Ama-241 ashiyekileyo amazinyo amancinci uhlala ehambelana 19 iintlobo ookrebe kunye imitha. Phakathi kweziphumo, iirekhodi zokuqala eMzantsi Melika zegenera zivelele. I-Sympterigia, I-Dipturus y IiRhinobatos kwirekhodi yefosili yendawo.

Ngaphaya koko, uphononongo lurekhoda iirekhodi zokuqala zefosili kwi-hemisphere esemazantsi i-basking shark (Cetorhinus maximus) y ingwe ukrebe (Triakis semifasciata), idatha eyandisa imephu yembali yezi ntlobo.

Amagama adibanisa inzululwazi nenkcubeko

I-Pochitaserra patriciacanalae ithwala imbeko ephindwe kabini: kwelinye icala, iyaliqonda ilifa lesayensi UPatricia CanalesNgakolunye uhlangothi, ikhupha iPochita ukuba igxininise into ephambili ye-anatomical ye-sawshark kwaye yenza kube lula ukuba uluntu lukhumbule igama.

Ababhali bagxininisa ukuba amagama enzululwazi kufuneka abe esichazayo nesikhumbulekayo, isicwangciso esiluncedo sokusasaza i-paleontology phakathi kwezizukulwana ezitsha ngaphandle kokuphulukana nokuqina kwezemfundo.

Okunye okufunyenweyo e-Bahía Inglesa

Umtha wachazwa ngokuhambelanayo. Dasyatis manuelcamposis, ecetywayo kumazinyo amabini amancinci abhekisela kuhlobo lwe-stingrays ekhoyo, nangona ngaphandle kwabameli banamhlanje kunxweme lwaseChile.

Ngobu bungqina, i-Bahía Inglesa Formation iqinisa isimo sayo njenge indawo yokukhangela EMelika, ilabhoratri yendalo yokwenyani yokwakhiwa kwakhona kwembali yoMzantsi wePasifiki kunye nebhayoloji yayo.

Ukufunyanwa kwePochitaserra kunye nokuchongwa kweerekhodi ezintsha ze-paleobiogeographical zigxininisa a iyantlukwano yaselwandle ephawulekayo kwi-Late Miocene, kunye nexabiso lokudibanisa umthamo omkhulu wentlenga kwizifundo ze-microfossil.

Uphando lunikezela ngomfanekiso ocacileyo we-ecosystem ukusuka kwizigidi zeminyaka eyadlulayo kwaye, ngaxeshanye, lubonisa ukuba inzululwazi inokuzibandakanya kwincoko ngenkcubeko yangoku ngaphandle kokuncama ukuchaneka okanye umxholo.
