Izilwane Triassic

Ukuthuthukiswa kwezilwane ze-Triassic

Ngaphakathi kwenkathi ye- Mesozoic Kube nezikhathi ezi-3 eziveze umehluko ekuziphendukeni kweplanethi yethu: I-Triassic, I-Jurassic y Okuhle kakhulu. Emugqeni ohlukanisayo owawukhona isikhathi sangaphambi kweTriassic, i- I-Permian, inqubo yokuqothulwa okukhulu yenzeke ezingeni leplanethi elenze ukuthi i-95% yazo zonke izinhlobo zezinto eziphilayo inyamalale. Lokhu kwenze ukuthi izilwane zeTriassic zimelele okuthile kokusetha kabusha kuyo yonke impilo emhlabeni. Izinhlobo ezimbalwa ezikwazile ukusinda kule nqubo yokuqothulwa okukhulu kudingeke ukuthi zivumelane nezimo ezintsha zasemhlabeni nezasolwandle.

Ngakho-ke, sizonikezela le ndatshana ukukutshela konke odinga ukukwazi ngakho Izilwane Triassic.

Ukuthuthukiswa kwezimbali zeTriassic

Isikhathi se-Triassic

Ngaphandle kwale nqubo yokuqothulwa okukhulu ezingeni lamaplanethi, kunezinhlobo eziningi zezilwane ezazikwazi ukuzivumelanisa nezinhlobo ezintsha zokuphila futhi, kancane kancane, ngokuhamba kwesikhathi bakwazi ukwehluka. Sonke lesi sikhathi, izitshalo zakha amahlathi amakhulu futhi kwakungama-dinosaurs aqala ukubusa iplanethi. Kwakuyizilwane empeleni ezazilawula zonke izindawo ezikhona, kokubili umhlaba, umoya nolwandle.

Sizobukeza kafushane ukuthuthukiswa kwezimbali ngalesi sikhathi. Ekuqaleni kwe-Triassic, izitshalo eziningi zaphela kusukela ngaleso sikhathi izimo zezemvelo bezingafanele kakhulu ukuthi zithuthukiswe futhi zahlukaniswe ngendlela efanele. Kungakho izitshalo ezakwazi ukuzinakekela ngemuva kwalesi sikhathi sokuqothulwa zingahlukahluka kalula ngoba izinga lomncintiswano laliphansi kakhulu. Izitshalo ebezingagcinwa futhi zahlukaniswa ngobuningi kakhulu ikakhulukazi lezo zeqembu lama-gymnosperms.

Lezi zitshalo zaziwa njengezitshalo ezingenalutho. Kuleli qembu lezitshalo, ama-conifers nama-cycads avelele. Abamele uhlobo lwe-gingko no-ferns nabo babefanelekile. IConifers imele iqembu lalezo zitshalo ngomhlangano okhuni, ojiyile futhi ongazwani nhlobo. Amaqabunga awo ayehlala eluhlaza futhi ngokuvamile e-monoecious. Lokhu kwenza izitho zabo, zombili owesilisa nowesifazane, lapho zizalana, zibe khona kumuntu ofanayo.

Ngakolunye uhlangothi, ama-cycads kwakuyilezo zitshalo ezinesiqu esinokhuni esingenalo uhlobo lwegatsha. Amaqabunga aso ayetholakala ekugcineni kwesitshalo futhi ayenama-dioecious. Lokhu kusho ukuthi kunabantu abahlukene besilisa nabesifazane. IGingko yayichichima kakhulu kulesi sikhathi futhi yizinhlobo zeGingko biloba kuphela eziphila namuhla. Ekugcineni, ama-ferns kwakuyizitshalo ezinemithambo yegazi ezazivele zingeqembu le-pteridophytes futhi ezine-phloem ne-xylem.

Ukuthuthukiswa kwezilwane ze-Triassic

Izilwane Triassic

Izilwane ezimelele kakhulu kulesi sikhathi zakhiwa ngamaqembu amabili: ezihuquzelayo nama-dinosaurs. Kwakungama-invertebrate akwazi ukufeza intuthuko enkulu ezingeni lemvelo yasemanzini. Ezinye izinhlobo zezilwane ezihuquzelayo nazo zavela ezindaweni zasolwandle futhi zakwazi ukubusa kakhulu olwandle.

Ngokuqondene nomoya, ezinye izilwane ezihuquzelayo zaqala ukubonwa ezazinokuzivumelanisa okuthile nezimo zemvelo zamanje futhi zikwazi ukundiza. Ukuze benze lokhu, babedinga ukuguqulwa okuhlukahlukene kokwakheka komzimba ukuvumelanisa izingalo nezitho zabo ukuze zindiza.

Sizothuthukisa ngokujulile zonke izilwane ze-Triassic.

Izilwane Zomhlaba Eziwumhlaba

Ngaphakathi kwalezi zimvelo, amaqembu ambalwa ezilwane anezici ezihlukile athuthukisiwe: izilwane ezinwabuzelayo ezincelisayo kanye nama-dinosaurs.

Izilwane ezinwabuzelayo zaseMammalia

Leli qembu laziwa ngegama lama-therapsids. Ngokwesimo somzimba besibona lezi zilwane ziyinhlanganisela phakathi kwenja nesibankwa. Imilenze yazo yayinde impela uma iqhathaniswa nawo wonke umzimba kodwa yayinemisila emifushane kakhulu. Amazinyo ayenezinhlobo ezahlukahlukene zokuma ngokuya ngokudla kohlobo ngalunye. Lapho ukudla bekuyinyoka kakhulu, siyabona ukuthi amazinyo akhuliswa kakhulu ngokuziphatha. Ama-molars asebenza ngokwengeziwe ukukwazi ukuchoboza izitshalo. Kodwa-ke, uma ngabe ukudla bekudla kakhulu, ububona intuthuko engcono yemigwaqo nezinyo lasebhusha.

Izibankwakazi Triassic

AmaDinosaurs kucatshangwa ukuthi avela sonke lesi sikhathi. Phakathi kwama-dinosaurs amele kakhulu sibona ama-prosauropods nama-theropods. Sizozihlaziya ngokuningiliziwe.

Ama-Prosauropods

Kwakuyizilwane ezinomthamo omkhulu futhi ezazinentamo enobude obukhulu. Ubude abulukhulu njengama-herbivores abephila ngesikhathi se-Jurassic. Amaphiko akhe angaphambili ayengathuthukile kakhulu kunasemuva. Ngaphakathi kwama-prosauropods kwakukhona ukuhlukana okuthile ngokwezinhlobo zezinto eziphilayo. Abavelele kwakunguMussaurus neSellosaurus.

Ama-theropods

Kwakungamanye amaqembu ama-dinosaurs ayevelele phakathi nalesi sigaba. Kwakuyiqembu lama-dinosaurs adla kakhulu. Phakathi kwezici zayo eziyinhloko sithola i-pipette gait kanye nezimbambo ezingakathuthuki kakhulu. Ubukhulu balezi zinhlobo babuhlukahluka kuye ngemvelo lapho zizotholakala khona. Njengoba ukuvela kwezilwane kwandulela ukuqothulwa okukhulu, ukuguqulwa kofuzo bekwenzeka ngejubane elikhulu. Lokhu kungenxa yokuthi izindawo zazishintsha kakhulu ngalezo zikhathi nokuthi nezimbali nazo zazinentuthuko yazo.

Ezinye izinhlobo zamatropods Azangeqile imitha kanti ezinye bezikwazi ukufinyelela kumamitha ayi-12. Ezinye zezinhlobo zethropod ezaziwa kakhulu kwakuyiTawa ne-Euroraptor.

Izilwane zasemanzini ze-Triassic

Ukuqothulwa kwePermian

Emvelweni wamanzi, ama-invertebrates athuthukile ikakhulukazi. Babemelwe mollusks phakathi zazo gastropods, bivalves futhi cephalopods ivelele. Amanye amakhorali nawo akhula olwandle.

Izilwane ezihuquzelayo zasemanzini nazo zazithuthuke kakhulu ngalesi sikhathi. I-Notosaurus ine-ichthyosaurs evelele. Mayelana nezilwane ezihuquzelayo ezisemoyeni kwakukhona neqembu lezilwane ezihuquzelayo ezakhula kahle maqondana nezinye. Futhi ukuthi bangakhiqiza uhlobo lwezinambuzane ezisuka esiqwini salo ziye emaphethelweni alo aphezulu. Lezi zitho zimenze wakwazi ukundiza. Kuleli qembu kukhona ama-Pterosaurs ayene-oviparous futhi enomlomo ohlangothini. Ukudla kwabo kwakudla kakhulu.

Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngezilwane zeTriassic.
