Kwa nthawi yayitali, anthu akhala akukhudzidwa ndi chithunzi cha ma dinosaur omwe ali pazenera, kotero kuti T-rex imaonedwa kuti ndi pamwamba pa mitundu yambiri ya ma dinosaur. Malinga ndi kafukufuku wa zinthu zakale, T-rex ndi yoyenera kuyima pamwamba pa unyolo wa chakudya. Kutalika kwa T-rex wamkulu nthawi zambiri kumakhala kopitilira mamita 10, ndipo mphamvu yodabwitsa yoluma ndi yokwanira kung'amba nyama zonse pakati. Mfundo ziwirizi zokha ndizokwanira kupangitsa anthu kulambira dinosaur iyi. Koma si mtundu wamphamvu kwambiri wa ma dinosaur odya nyama, ndipo wolimba kwambiri ndi Spinosaurus.
Poyerekeza ndi T-Rex, Spinosaurus si wotchuka kwenikweni, zomwe sizingasiyanitsidwe ndi momwe zinthu zinalili kale. Poganizira momwe zinthu zakale zinalili kale, akatswiri a paleontologist amatha kupeza zambiri zokhudza Tyrannosaurus Rex kuchokera ku zinthu zakale kuposa Spinosaurus, zomwe zimathandiza anthu kufotokoza chithunzi chake. Maonekedwe enieni a Spinosaurus sanadziwikebe. M'maphunziro am'mbuyomu, akatswiri a paleontologist adazindikira Spinosaurus ngati dinosaur wamkulu wodya nyama wa theropod pakati pa nthawi ya Cretaceous kutengera zinthu zakale za Spinosaurus zomwe zinafukulidwa. Malingaliro ambiri a anthu pa izi amachokera pazenera la kanema kapena zithunzi zosiyanasiyana zobwezeretsedwa. Kuchokera ku deta iyi, zitha kuwoneka kuti Spinosaurus ndi yofanana ndi nyama zina za theropod kupatulapo misana yapadera ya dorsal kumbuyo kwake.
Akatswiri a zinthu zakale amanena maganizo atsopano okhudza Spinosaurus
Baryonyx ndi wa m'banja la Spinosaurus m'magulu. Akatswiri a zinthu zakale anapeza kuti pali mamba a nsomba m'mimba mwa nyama yakale ya Baryonyx, ndipo ananena kuti Baryonyx amatha kusodza. Koma sizikutanthauza kuti ma spinosaur ndi a m'madzi, chifukwa zimbalangondo zimakondanso kusodza, koma si nyama za m'madzi.
Pambuyo pake, ofufuza ena adaganiza zogwiritsa ntchito ma isotope poyesa Spinosaurus, potengera zotsatira zake ngati umboni umodzi wotsimikizira ngati Spinosaurus ndi dinosaur ya m'madzi. Pambuyo pofufuza za isotopic za mafupa a Spinosaurus, ofufuzawo adapeza kuti kufalikira kwa isotopic kunali pafupi ndi kwa zamoyo zam'madzi.
Mu 2008, Nizar Ibrahim, katswiri wa zinthu zakale ku yunivesite ya Chicago, adapeza gulu la zinthu zakale za Spinosaurus zomwe zinali zosiyana kwambiri ndi zinthu zakale zodziwika bwino pamgodi ku Monaco. Gulu la zinthu zakalezi linapangidwa kumapeto kwa nthawi ya Cretaceous. Kudzera mu kafukufuku wa zinthu zakale za Spinosaurus, gulu la Ibrahim limakhulupirira kuti thupi la Spinosaurus ndi lalitali komanso lochepa kuposa momwe likudziwikira pano, ndi pakamwa ngati pa ng'ona, ndipo mwina linakula ndi zipsepse. Zinthu zimenezi zikusonyeza kuti Spinosaurus ndi nyama zam'madzi kapena za m'madzi.
Mu 2018, Ibrahim ndi gulu lake adapezanso mafupa a Spinosaurus ku Monaco. Nthawi ino adapeza vertebra ya mchira wa Spinosaurus yosungidwa bwino komanso zikhadabo. Ofufuzawa adafufuza mozama vertebra ya mchira wa Spinosaurus ndipo adapeza kuti ili ngati gawo la thupi lomwe lili ndi zolengedwa zam'madzi. Zomwe zapezekazi zikupereka umboni wina woti Spinosaurus sanali cholengedwa chapadziko lapansi chokha, koma dinosaur yomwe ingakhale m'madzi.
AnaliSpinosaurusdinosaur wapadziko lapansi kapena wa m'madzi?
Kodi Spinosaurus ndi dinosaur wa padziko lapansi, dinosaur wa m'madzi, kapena dinosaur wa m'madzi? Zomwe Ibrahim anapeza m'zaka ziwiri zapitazi zakhala zokwanira kusonyeza kuti Spinosaurus si cholengedwa cha padziko lapansi mokwanira. Kudzera mu kafukufuku, gulu lake linapeza kuti mchira wa Spinosaurus unakula msana mbali zonse ziwiri, ndipo ngati unamangidwanso, mchira wake ungafanane ndi chombo choyendera. Kuphatikiza apo, msana wa Spinosaurus unali wosinthasintha kwambiri muyeso wopingasa, zomwe zikutanthauza kuti amatha kusuntha michira yawo pamakona akulu kuti apange mphamvu yosambira. Komabe, funso loti Spinosaurus ndi ndani kwenikweni silinathetsedwebe. Chifukwa palibe umboni wotsimikizira kuti "Spinosaurus ndi dinosaur wa m'madzi kwathunthu", kotero akatswiri ambiri a paleontologist tsopano akukhulupirira kuti mwina ndi cholengedwa cha m'madzi ngati ng'ona.
Ponseponse, akatswiri a paleontologist ayesetsa kwambiri kuphunzira za Spinosaurus, akuulula chinsinsi cha Spinosaurus pang'onopang'ono kwa dziko lapansi. Ngati palibe mfundo ndi zinthu zomwe zapezeka zomwe zimasokoneza chidziwitso cha anthu, ndikukhulupirira kuti anthu ambiri amaganizabe kuti Spinosaurus ndi Tyrannosaurus Rex ndi nyama zakuthengo. Kodi nkhope yeniyeni ya Spinosaurus ndi yotani? Tiyeni tidikire tiwone!
