Masayendisiti anobva kuyunivhesiti yeNew England muAustralia akakwanisa kuziva kuti zvakadyiwa nekatani yeanenge tanzi. Izvi zvakaitwa kuburikidza nekudzidza kwezvinhu zvakachengetwa zvemhando mbiri dzevagari venzvimbo dzakadzika dzegungwa - Redlichia Rex uye Olenoides Serrus.
Mazana emamirioni emakore apfuura, Trilobites akazadza magungwa ekare. Iye zvino zvisinganzwisisike zvavanyori vaunganidzwa kubva kuShale Kuumbwa Kuzadza Mamuseum Solves uye eBay zvitoro. Pasinei nekuzivikanwa kweanenge tanze mushure mekunyangarika, zvichiri zvakawanda nezvehupenyu hwavo anoramba chakavanzika. Chidzidzo chitsva chinobatsira kutsanangura kuti vamwe marudzi ekare vakavhimwa sei uye vanodyiswa uye vasimbise kugona kweimwe nzvimbo yakakura kuparadza magorodhi. Achishandisa zvipenyu zvakanyatsovonekwa, dzidziso dzepanyama dzakafunga kuenzanisa neuchenjeri hwechisimba chebhiza kuitira kuti vagari vemo vekare vezvakanyorwa zvemvura vakavheswa uye vanodyiswa.
Sezvakataurwa munyaya yacho nekuenderera mberi kwenyaya yeRoyal Society b, maHorseshoe crabs vasati vadya molusks vanoshandisa maasendimendi iri kutenderedza muromo. Trilobites airatidzika kunge bhiza crab uye zvimwe akatama pamwe chete neanotenda Russell Bicnell Bicnell mutungamiri wenyaya uye mushandi weYunivhesiti yeNew England.
Nyanzvi, pamwe chete nevanoshanda navo, mushure mekuongorora marudzi maviri akasiyana siyana ematanho ematanho, akatsunga Redlichia Rex - Yekutanga yaive imwe yerudzi rwakafanana rweCambrian. Mutauri uyu weMarine Arthropod ndiye "akafamba tangi" "Big yakaipa Zverem" akaisa munyori webasa. Mapepa aTterlobita aive mapenzi aive nemucheto-wakaumbwa mharidzo senge simbi nutcracker. Kana dziri iyo Olensides Serrus, yakanga iri diki ine spikes pamativi uye kumashure. Zvidiki zvidiki zvakatenderedzwa zvakafukidzwa nehurefu hwakareba senge tsono.
Kuti uwane kuti izvi zvinokatyamadza sei matsime azvo zvekudya zvikafu zvekudya Dr. Bicnell uye timu yake vakatendeukira kuongororwa kwezvinhu zvekupedzisira nenzira yekuenzanisa kwemuviri masisitimu emuviri. Pakutanga akafunga kuti mainjiniya, zviri kuwedzera kufarirwa munhoroondo dzehupenyu sezvinoita vatsvagiri kuti vazviratidze kuti vanzwisise zviri nani zveAnatomy yekare uye zviripo. Biologists akaongorora zvekare zvibodzwa zvezvibodzwa zvekuziva kuti uzive nezvikwereti zvavanogona kurarama. Kuti uenzanise, vakafanana nedzimwe yekare Arthropod Sidney Unecpectans - Anokurumbira "Kupwanya" kweShells - pamwe neine bhiza bhiza. Vakabva vaenzanisa mhedzisiro.
O. Serratus aisakwanisa kupinda mukati zvisikwa zvine shell - yake yakareba spikes yaigona kutyora. Panzvimbo pezvo, zvimwe aishandisa spikes nekukuya kweanababa uye kupfava kwakapfava sehonye. Nekudaro, R. REX yakanyatsogadzirwa kupwanya. Zvinoenderana nekuongororwa kwekuzvimiririra kwake kunogona kutsungirira simba rakawanda kupfuura remuchekuita Sekureva kwaDr. Bicnell, aigona kunyatsoita mukudya kucheneswa kwemugodhi kusanganisira mamwe tronebites uye kunyangwe vamwe vedziri vatsva.
Iko kushandiswa kwerudzi urwu kwekuedzwa kwekuedzwa kunoita kuti zviitike zviri nani "mabasa ezvikamu zvechinyorwa zvisingaonekwe neimwe nzira," akadaro Karen Moreo Paleontologist kubva kuAustralia University haina kutora chikamu mukudzidza. Panguva imwecheteyo, imwe data, yakadai senzvimbo yemhasuru yeiyo yekare articraft kana zvivakwa zveExoskeleton, hazvizivikanwe uye zvinofanirwa kutsanangurwa nemhedziso chaiyo uye yekupedzisira yaisakwanisa kucherechedzwa nyanzvi.
