Saber-toothed ikati - i umhlaseli yokuqothulwa

Iningi lethu zijwayele inkampani tasendlini. Abaningi, ukuze kukhanye up isikhathi sakho sokungcebeleka, uzozala izilwane ezincane ubuka ka umndeni ikati. Kodwa neze ubani ecabanga yokufana kwawo yokuqothulwa engaba iminyaka eyizigidi eziyi-70 edlule izilwane ezidla ezinye okuthiwa amakati saber-toothed.

izindawo

izinto eziphilayo yaqhakaza amasimu amazwe ase-Afrika futhi ahlala Eurasia kanye North American amazwekazi ku Miocene ekuseni futhi phakathi. Omunye abameleli bakhe bokuqala - Pseudaelurus quadridentatus - kubhekwa umsunguli we ukuziphendukela kwemvelo kwezinhlobo.

Esikhathini Miocene ngasekupheleni saber-toothed ikati sihlukanisa indawo carnivores barburofelisami kokuba phambi abukhali namazinyo Canine. Izinsalela zokugcina kwezinhlobo nabameleli bayo zinyamalale kusukela Earth eminyakeni eyizinkulungwane 10 edlule. Iningi labantu base-iplanethi is hhayi bahlangana.

Ukuvela amakati saber-toothed

Njengoba ummeleli jikelele silwane kwanyamalala ebusweni Zomhlaba isikhathi eside, iningi ulwazi ngakho - ososayensi bayaqagela. Kodwa nge ukuthuthukiswa zofuzo kungenzeka ukuthola amaqiniso amasha ezithakazelisayo mayelana izinto eziphilayo. Ukutadisha imivubukulo, ungakha umfanekiso othile bese sifunde ngalezi zidalwa Ayindida.

Ososayensi basikisela ukuthi ikati saber-toothed kanye nemikhuba ekuzingeleni kwadingeka ukufana okukhulu ne Tigers, kodwa ayikaze ingxenye yalo mkhaya. Imivubukulo zehlulekile ukufakazela ukuthi izilwane kwakufanele tiger yokudweba imivimbo noboya Fluffy. Futhi, babungekho ubufakazi ukusekela kufana imikhuba lasendulo zamakati nezinhlobo yesimanje, ngakho lezi izitatimende kubhekwe njengento ezizathwini.

Ucwaningo lwesayensi esekelwe cwaningo DNA, eyayiqhutshwa 2005, waqinisekisa Ukukhethwa subfamily "amakati saber-toothed" kusukela okhokho ezifuywayo zethu, kodwa musa iyihlanganise ne Elisengozini zinhlobo zamanje.

Ummeleli ejwayelekile lokhu Iqembu labacwaningi ukholelwa ukuthi kuzosetshenziswa izinto ezinikeza amandla eyaziwa saber-toothed ihlosi, ongazange basonta abameleli tiger cat in the age ice. Ezweni yesayensi, igama lakhe Smilodon, okuyinto uhumusha kusuka Latin ngokuthi "kwabo umbhubhisi."

Smilodon: uhlobo incazelo

Smilodon - owokugcina "amakati saber-toothed" subfamily. Animal isithombe layout okumangalisayo:

• omkhulu, kuze kufinyelele 20 amasentimitha canines;
• Ukuphakama at sokubuna ifinyelela imitha futhi 20 cm;
• Ubude yomzimba amamitha engaphezu kwemibili;
• isisindo imayelana 500 kg.

Lezi zimo zokuma ukwenza lezi zilwane amakhosi ahamba ingxenye enkulu yensimu. Enye yawo kwakunguyise kuphela ubude nomsila 30-35 ngamasentimitha. Yakha esiyisigqigqi wazitshaya Smilodon engajwayelekile abameleli ikati. womhume kuphela American izingonyama kwakungafanele zingaphansi kwakhe ngosayizi.

Akungabazeki ukuthi isilwane kwaba nomzingeli. Bambalwa ababekwazi ukusinda uma kwesokunxele yokuzingela ikati saber-toothed. Photo ngabanye skeleton wako zenziwa ososayensi lapho bemba eFrance.

Ekhona kanye nabanye abameleli kwezilwane, amakati babe ancintisanayo ngezizathu ukuzingela yokuhlala:

• gepardovymi futhi panterovymi emazweni Afrika;
• Pumas, amabhubesi, jaguar e-United States.

ukubukeka

Raptors efakiwe ukuma oyindilinga futhi Amazinyo saber-toothed. Smilodon emhlathini isakhiwo kwakusobala kangangokuthi ivumela ngomlomo wesilwane ukuze embule kuze kufinyelele 95 °, abameleli banamuhla izilwane ezidla ezinye Elisengozini bayakwazi ukukwenza ngenxa kungekho kuka 65 °. Bare, namazinyo esigwegwile ngoba nokucija okusikhumbuza izindwani. Ubude bafika 20 cm. Isilwane onaMandla wakwazi yokuzingela nezinye izilwane esingeqile lingakanani. Nasi ikati saber-toothed, olubheka okwesabisayo abakhileyo zwekazi American iminyaka eyizigidi ezimbili edlule.

Ngomhlathi we-isilwane okuhloswe ukubulala, asondeze isilwane e inombolo ezidla yingozi. Wayengenaso abaphikisi ontanga.

esifubeni Yamandla isisindo ngumuntu ikota phezu isisindo izilwane ezinkulu ingonyama bavunyelwe ezidla kwendawo hhayi kuphela nomunye kodwa futhi ne iDemo abami bear, hhayi isilo oqinile futhi aqine kancane. Usayizi obukhulu umzimba, ehlanganisa imisipha, namazinyo-imimese uvumele nomzingeli ngekudla abameleli ebaluleke kakhulu nezilwane wesikhathi - mammoth.

Ososayensi bayavuma ukuthi akunakwenzeka ukuqhathanisa inkomo nge ibhubesi. Yebo, yakhe usayizi umzimba efana Ubukhulu yenkosi ezilwane, kodwa ukwengeza isakhiwo, ingxenye bese bakha ngezidladla omkhulu phambi ku isizinda ezingemuva iDemo ungavumeli ukwenza ukuqhathanisa okunjalo.

intamo kwemisipha ne bite amandla evumela ezifuywayo, washo inyamazane gingqika phansi izimpiko zakhe izinyembezi. Ezweni yesayensi namanje mpikiswano mayelana eside Alondoloza, njengoba ikati saber-toothed ukuthi ngesineke. Predator, cishe, akabanga bendabuko tiger stripes. Cishe, isikhumba sakhe ehlotshiswe amnyama.

uyathola nezakudala

Ososayensi abakwazi ukutshela isizathu sangempela esenza lolu hlobo ezidla kwaguqulwa kokuba yonke idatha okusinda, yanyamalala ebusweni Earth. Kuphela izinsalela zamathambo amathambo namazinyo isici okusikhumbuza isilwane enegama zamakati saber-toothed. Found ku emazweni Los Angeles onesihloko esithi "The Magic Mile" hit emhlabeni zobuciko yesimanje of America nezakudala.

Lakes namachibi endaweni ezishisa kakhulu zikhipha izinhlayiyana mbhangqwana, kuyethusa futhi kusukela ekujuleni komhlaba sizibonise resin ukuhwamuka. Lapha kulapho abavubukuli nenhlanhla yokuthola izinsalela amathambo isilwane, nezinye izilwane ezidla ezinye eziningi yokuqothulwa. Amaxhaphozi ka resin okucashile guschey amahlathi saba bucayi ezilwaneni eziningi izilwane zasendle. amagatsha esinezimila imfucumfucu akha isicupho omkhulu. Ezidla uhlaza yizinkulumo kubo, ngaleyo ndlela edonsa izilwane ezidla ezinye, okuyinto elinde zabulawa.

Kumbiwa endaweni La Brea aletha eziyinkulungwane Smilodon amathambo, abenze inamba engafani eyaziswa. Asphalt ne resin ngokugcwalisa namachibi kwaba indaba enhle uyalondoloza. Amathambo kuyagcinwa isesimweni enkulu. Ososayensi bakwazi ukwenza kubo umqondo wokuthi ukubheka amakati saber-toothed. Izithombe ezitholakala izinsalela zamathambo ingatholakala iminyuziyamu anthropological.

Kufanele kuqashelwe ukuthi i-short-abami bear amathambo impisi atholakala phakathi izinsalela engu ice. Lawa oqondile okhokho carnivores abaphila emhlabeni namuhla. Kodwa nakhu ikati saber-toothed ongawushiyanga ngemuva nzalo. Okwamanje Asitholanga uhlobo izindlalifa oqondile Smilodon, machairodus nezinye izinhlobo amakati saber-toothed.

izici zokuziphatha

Ngokusekelwe izici ukubukeka, saber-toothed ikati, oziphatha kwakuhlukile ulaka, ngangingakwazi ukunyakazisa ngokushesha okukhulu kakhulu. Lokhu kungenxa nomsila short, okuyinto ayikuvumeli ukuba ukugcina umzimba ubheke phezulu ngesikhathi ugijima okusheshayo. Kungenzeka, le sesilwana ayeqamekele, elinde isisulu, futhi ngokushesha wamshaya.

Njengoba sekuzoqala isikhathi Pleistocene, nemihlambi ezidla uhlaza ayemakhulu kakhulu. Zaziziningi izilwane akuzona ukuthi kunzima ukuzenzela ukudla. Ezinye ezidla uhlaza babe Ubukhulu omkhulu, okuyinto akazange avumele ukungasabeli kahle ikati yokuzingela wedwa. Kungenzeka ukuthi usesimweni esinjalo, Predators yokuzingela ku amaphakethe. Ngesikhathi kumbiwa eduze amathambo ezilwane herbivorous amanxiwa kancane ossified ka amasampula amahlosi saber-toothed.

Ukuthatha ukunakekela umhlambi

Iqiniso izinsalela ihlosi kungadaleka ingozi embi kakhulu, ungavumeli kuye yokuzingela wedwa, kusikisela ukuthi kungenzeka ngezilwane ezihlala imihlambi, lapho ngisho kwesilwane esilimele bangaba khona nge abazingeli nezinye.

Ezingokwemvelo Kanye Nezenzo kunenzuzo nganoma yisiphi isidlo nomzingeli izenzo inyama. Smilodon ingathiwa a giperplotoyadnym. Izinsalela amathambo abo amahhashi amhlophe, inyathi watholakala.

Kungani zidinga namazinyo ezinjalo?

Umbuzo we khona kwamazinyo nomzingeli enganikanga ukuphumula ososayensi. Phela, ingonyama okuzingela ayidingi namazinyo-sabres. Kuze kube yimanje, ososayensi inhlolo-vo lokuphinda amandla ngemva kokulunywa ikati. Kwatholakala ukuthi cishe izikhathi ezimbili leliphasi kunaleyo engonyama. It kuvela ukuthi amabhubesi yesimanje ukuluma amandla inquma usayizi isisulu.

Amazinyo izinyoni nezakudala kwadingeka amandla ezibulalayo uma esetshenziswa emuva naphambili. Movement ngapha nangapha lalingabulawa kalula kulimaze kubo, umane breaking. Jams Canine emzimbeni lohlaselwayo kulula ukugqashula kuyo. Nokulahlekelwa izinyo ngesigamu kunciphisa kungenzeka wokufuna ezinezithelo, futhi wamesabisa ngokuthi ukufa ngenxa yendlala.

Umbono wokuthi izilwane abalimele egade bangadla kiyo njengoba amalungu abo iphakethe, ososayensi abazange ukuqinisekisa noma ukuphika. Mhlawumbe eka- emazinyweni kwenza okholwayo wangakwazi siphile ilungu kwezinhlobo namuhla. Kodwa lena umbuzo ososayensi.

Kubi kodwa ethandwa

Ngohlobo Lomuntu Okufanele Ube nomzingeli komlando, ngisho adalwe lwamathambo uhlala, okubangela ukuthuthumela okuncane. Nokho, amakati saber-toothed zithandwa hhayi kuphela mshini izwe uthola. Ukubona i-strong, ummeleli ice age ekhohlisayo yasungulwa multipliers in the ifilimu efanayo. On zezingane t-shirts, izimpawu kanye nojosaka babe nomfanekiso waso. isilwane izibalo ingatholakala esitolo ithoyizi.

Sifuna ukuhlobanisa yonke engaziwa futhi buyamphunyuka izici izikhulu okunemibandela. Yiqiniso, saber-toothed tiger - yasungulwa abaculi, kodwa ukwakha isithombe sakhe esikrinini usebenzisa umninindlu uhlobo, acabangele izici skeleton isilwane, empeleni wahlala Emhlabeni eminyakeni eyizigidi edlule. Ngisho ukubukela cartoon, singabona isisulu sakhe ukuzimela ukuzimela.
