I-Dilophosaurus ngokungangabazeki ingenye yama-dinosaurs aziwa kakhulu namuhla, ngenxa yokuvela kwayo efilimini yokuqala ye-trilogy ye-"Jurassic Park" ngo-1993. Yayihlala ekuqaleni kweJurassic eNyakatho Melika yanamuhla. Igama laso lisho ukuthi "i-two-crested lizard". Njengamanye ama-theropods, yayibonakala ngokuba nezinzipho ezi-3 emaphethelweni ayo kanye nokuba namathambo angenalutho.
Ngo-1954 kwachazwa izibonelo zokuqala zalesi silwane. Nokho, alizange linikezwe igama lakhe kwaze kwaba seshumini leminyaka kamuva. Nakuba i-Dilophosaurus ingenye ye-theropods ye-Jurassic endala kunazo zonke, futhi ingenye yezingaqondakali kakhulu namuhla. Namuhla Kuthathwa njengohlobo lomndeni wakwaDilophosauridae.
Incazelo ye-Dilophosaurus
Le nyama edla inyama ephindwe kabili ingaba amamitha angu-7 ubude, amamitha angu-3 ukuphakama kanye nesisindo esingamakhilogremu angu-400. Ngenxa yalesi sizathu iba enye yezilwane ezidla ezinye ezinkulu, nakuba incane kunamanye ama-theropods ngemva kwayo. Wayenomzimba omncane, okhanyayo futhi ugebhezi lwakhe lwalulukhulu ngokulingana nomzimba wakhe. umlomo wayo wawumngcingo futhi unesikhala sekhala emhlathini ongenhla. Nokho, Okwakugqama kakhulu ngalesi silwane esihuquzelayo amaqoqo aso amabili amade ayesekhanda laso. Njengamanje, umsebenzi wabo awukaziwa. Amazinyo e-Dilophosaurus ayegobile futhi made.
Kucatshangelwa ukuthi lesi silwane esizingelayo kungenzeka ukuthi bezingela izilwane ezinkulu, kanye nezinhlanzi nezilwane ezincane. Futhi, kungenzeka ukuthi wakhula ngokushesha. Kulinganiselwa ukuthi ingakhula ibe ngamasentimitha angama-35 unyaka ngamunye ezigabeni zokuqala zokuphila kwakhe.
amagquma
Kuyaphikiswana kakhulu ukuthi wawuyini umsebenzi wangempela wemibhalo ye-Dilophosaurus. Imisebenzi engenzeka ihlanganisa i-thermoregulation, kodwa lo mbono uthathwa ngohlamvu lukasawoti njengoba i-cristae yayingenayo imigodi ye-vascularization. Okunye okungenzeka kungaba ukusetshenziswa kwayo emibukisweni yocansi., esimweni esinjalo kungase kucatshangwe ukuthi amaDilophosaurus ayehlala ngamaqembu. Ukuthi zingase zisetshenziswe ezimpini akuwona neze ngenxa yobuthaka bazo.
Ngonyaka ka-2011, izazi ezimbili ze-paleontologist zaseMelika uKevin Padian noJohn R. Horner bahlongoza inkolelo-mbono entsha. Ngokusho kwabo, zonke "izakhiwo eziyinqaba" ezifana nama-crests, izimpondo, ama-domes, nama-frills abonakaliswa kuma-dinosaurs. Ayesetshenziswa ukuhlukanisa izinhlobo ezahlukene., njengoba abukho ubufakazi besayensi bokuqinisekisa okunye ukusebenza. Izazi ze-paleontology uRob J. Knell noScott D. Sampson basabela kulo mbono ngonyaka ofanayo. Bakuphikisa lokho lo mbono kungenzeka kakhulu njengomsebenzi wesibili yale mihlobiso. Kodwa-ke, babona ukusetshenziswa kwayo okuhlobene nokukhethwa kobulili njengamathuba amaningi, njengoba kuhlanganisa izindleko eziphakeme kakhulu zokuthuthukisa izakhiwo ezinjalo. Ngaphezu kwalokho, zazihlukahluka kakhulu phakathi kwezinhlobo ezifanayo.
Ukudla kwe-Dilophosaurus
Kuze kube namuhla akwaziwa kahle ukuthi kwakuyini ukudla kweDilophosaurus. Izwe le-paleontology lihlukaniswe phakathi kwemibono ehlukene mayelana nokuphakelwa kwaleli dinosaur.
Isazi sesayensi yezinto eziphilayo saseMelika uSamuel P. Welles sasiqiniseka ukuthi lesi silwane esizidlayo sasiwumfudlana. Uveze ukuthi igebe le-subnarial yikho okudale ukuthi ukulunywa yi-dinosaur kungabi namandla kakhulu. Ngaphezu kwalokho, u-Welles akatholanga lutho olubonisa ukuthi ugebhezi lwe-Dilophosaurus lwalune-cranial kinesis. Lesi sici senza kube nokwenzeka ukuthi ukunyakaza kwamathambo axegeyo ogebhezi kuhlobane. Ngakho-ke, lesi sazi se-paleontologist sacabanga ukuthi i-Dilophosaurus isebenzisa amazinyo ayo ukuze iklebhule futhi ibhoboze, futhi ingalumi. Wayenombono wokuthi uma ngempela ehlasela ezinye izilwane, angakwenza ngezinzipho zakhe kuphela.
Ngonyaka ka-1986, esinye isazi semivubukulo saseMelika okuthiwa uRobert T. Bakker sasho lokho i-Dilophosaurus yayijwayele ukuzingela izilwane ezinkulu nokuthi yayinamandla ngokwanele ukubhekana nezilwane ezidla uhlaza ezivela e-Lower Jurassic. Eminyakeni emibili kamuva, u-Welles wayichitha inkolelo-mbono yakhe yokuqala, echaza ukuthi ikhala lenyamazane lalijwayele ukuzingela kunalokho ayekucabanga ngaphambili. Ngaphezu kwalokho, amazinyo ayo abulala kakhulu kunezinzipho zayo. Uyakuqagela futhi lokho wayekwazi ukugxuma emsileni wakhe, njengoba kwenza amakhangaru anamuhla, kuyilapho ehlasela inyamazane yawo.

Ingabe i-Dilophosaurus mhlawumbe yayisidla izinhlanzi?
Ithiyori yakamuva iqagela ukuthi i-Dilophosaurus kungenzeka ukuthi yadla izinhlanzi. Ngo-2007, uMilner noJames I. Kirkland baphawula ukuthi iziphetho zemihlathi ye-dinosaur zenza i-rosette yamazinyo ahlangene njengoba enwebeka emaceleni. Lesi sici singabonakala kwezinye izinhlobo ezidla izinhlanzi, njengama-spinosaurid noma ama-gharials. Ngaphezu kwalokho, yayinezikhala ezihoxisiwe ezazingaba usizo ekugcineni amanzi amaningi ephuma emakhaleni ngenkathi edoba. Ekugcineni, kusamele kuqashelwe ukuthi, njenge-Spinosaurus, yayinezingalo nezinzipho ezinde ngokwanele ukuba idobe ukudla kwayo.
Curiosities
Ngesikhathi kumbiwa ngo-1966 eRocky Hill, e-United States, kwakhiwa i-Interstate 91, kwatholakala imilobo yezinyawo ze-dinosaur efana ne-Dilophosaurus. Ngakho-ke, le carnivore yakhethwa njenge-dinosaur yesifunda sase-Connecticut ngonyaka ka-2017. Kwatholakala ukuthi indawo okutholwe kuyo imilobo yezinyawo bekuyichibi le-Triassic. Ngenxa yalokhu kwanqunywa ukuhambisa umgwaqo futhi kwasungulwa ipaki ebizwa ngokuthi "Ipaki Yesifunda SeDinosaur". Ngo-1981, ukwakhiwa kabusha kobukhulu bokuphila bokuqala kwe-Dilophosaurus kwanikelwa kuleli paki. Lesi silwane ekuqaleni sasihlongozwe njenge-dinosaur yombuso wase-Arizona ngo-1998. Nokho, lesi sicelo sanqatshwa njengoba i-Dilophosaurus yayingeyona kuphela kuleyo ndawo, futhi udumo lwanikezwa i-Sonorasaurus.
Kusukela ku-fossil kuya kunkanyezi yaseHollywood
Bonke abalandeli be-dinosaur bezwile nge-Dilophosaurus edumile. Lena inomzuzu wayo oyinkanyezi efilimini yokuqala ye-franchise "Jurassic Park" eqondiswa uSteven Spielberg, kanye nasencwadini ebhalwe nguMichael Crichton. Kule filimu, umhlaseli uhlasela isisebenzi sasepaki esizama ukubaleka namasampula e-DNA entshontshiwe ngesikhathi kunesiphepho esibhubhisayo. I-Dilophosaurus, njengombukiso ohlaselayo, ikhipha ulwelwesi lwentamo ehoxayo futhi ikhafulele isihlungu emehlweni esisulu, njengoba kwenza ezinye izinyoka zesimanje. Ngemva kokuphuphuthekisa indoda empofu, iyamhlasela futhi imshwabadele. Ngeshwa, lezi zici ezimbili kube ngesinye seziqalo eziningi zaseHollywood. Abukho ubufakazi besayensi obubonisa ukuthi i-Dilophosaurus yayinolwelwesi oluhlehlayo noma ukuthi yayingakhafula ubuthi.
Futhi, ku-"Jurassic Park" i-Dilophosaurus incane kune-Velociraptor evezwe efilimini, empeleni esekelwe ku-Deinonychus. Nokho, i-Dilophosaurus yayinkulu ngokuphindwe kabili, njengoba sixoxile ngenhla. Lokhu kwenza lesi silwane esizingelayo esidumile sibe i-dinosaur "eqanjiwe" kunazo zonke ku-franchise.

Ngodumo lwe-trilogy, imikhiqizo eminingi esuselwe nayo yafika, njengamathoyizi nemidlalo yevidiyo, lapho lesi silwane esidumile seJurassic singeke siphuthelwe.
