<prompt> Fingqa isihloko: Ososayensi bathole ukuthi isilwane esidla ezinye esihlome ngamanqina ayisithupha amade sasilokhu sizulazula olwandle eminyakeni engaphezu kwezigidi ezingu-500 edlule futhi sasiphakathi kokhokho bezinambuzane zanamuhla, izicabucabu nama-lobster. I-Yawunik kootenayi efana ne-lobster yayinamehlo amane nezinselo ezinde ezinjengesiswebhu ezaziqala emaphethelweni ezinzipho zayo. Izingalo ezine nazo zazinemigqa yamazinyo ayephambene ayesiza lesi silwane ukuba sibambe inyamazane yaso olwandle lwangaphambi komlando wesikhathi seCambrian. Skrolela phansi ukuze ubone ividiyo. I-Yawunik kootenayi, eboniswe kulokwakhiwa kabusha okungenhla, yayihlala olwandle eminyakeni eyizigidi ezingu-508 edlule. Kutholakale ifosili yalesi silwane esibukeka siyinqaba eMarble Canyon engxenyeni esenyakatho yeKootenay National Park eCanadian Rockies. Izazi zezinto zakudala zithi cishe lolu hlobo lwalungelinye lama-arthropod okuqala adla inyama ayezulazula emhlabeni - iqembu kamuva elaguqukela ekubeni izicabucabu, ama-lobster nezinambuzane. Ucwaningo olusha luthole ukuthi izilwane zasemanzini nezasolwandle ezinjengengwenya ezazilingana nemoto encane zazibusa amachibi angaphambi komlando eminyakeni engaphezu kwezigidi ezingu-200 edlule. Izazi zezinto zakudala zathola izinsalela ze-super salamander ngesikhathi zimba endaweni echibini lasendulo eningizimu yePortugal. Lesi silwane esidla ezinye, esakhula saba amamitha amabili 6.5 ft ubude futhi sahlala emachibini nasemifuleni ngesikhathi seTriassic Period, saqanjwa ngokuthi iMetoposaurus algarvensis. Ngomlomo ogcwele amazinyo abukhali anjengenaliti, kucatshangwa ukuthi yayidla izinhlanzi kodwa futhi yayingagxumagxuma noma yimaphi ama-dinosaur amancane okuqala ayesondela kakhulu emanzini. Lesi silwane esiyizilwane ezidla ezinye, esasinamathambo angaphandle njengamanye ama-arthropod, kucatshangwa ukuthi saphila eminyakeni eyizigidi ezingu - 508 edlule. UCedric Aria, isazi sezinto eziphilayo zokuziphendukela kwemvelo eYunivesithi yaseToronto owayeyingxenye yeqembu elathola lezi zinhlobo, wathi: Lesi sidalwa sandisa umbono wethu ngokwakheka kwezitho zomzimba nemikhuba yokuzingela yama-arthropod okuqala, iqembu elihlanganisa izicabucabu nama-lobster. Ikhona...  <response>: I-Yawunik kootenayi yatholakala eMarble Canyon e-Canadian Rockies. Lesi silwane siyisilwane esiyizilwane ezidla ezinye esasibhukuda olwandle lwaseCambrian. Lezi zinsalela zivela eqenjini elaba yimbangela yokuvela kwezicabucabu, izinambuzane nama-lobster. Ososayensi bathi lalinamalungu amabili angaphambili anezinzipho ezintathu ezinde ngakunye.
