Ikhadi le-Dino No. 1567 kwangu-2 027

Sabre-toothed cat

Igama lisho ukuthi: “izinyo elinjengommese noma izinyo elibukhali ezinhlangothini zombili”1

Udla: InyamaIzinganekwane zasenduloI-Cenozoic, inkathi yezilwane ezincelisayoAkuyona i-dinosaur, kodwa inganekwane yasendulo

I-Smilodon yayiyikati elinamandla lasendulo elinamazinyo amakhulu afana nemimese. Ivame ukubizwa ngokuthi ingwe enamazinyo amade, kodwa yayingeyona ingwe nhlobo. Lezi zilwane ezizingelayo zaziphila e-Americas ngesikhathi se-Ice Age.1

Lona akuyena u-dino, kodwa ungomunye wezilwane ezidume kakhulu ezikhathini zasendulo, ngakho uthola indawo ku-Dino Wiki.

I-Smilodon yayidla ini?

Yayidla izilwane ezinkulu ezidla utshani ezifana nezinkomo zasendle, amakamela, ama-sloth aphansi namahhashi. Yayiyisilwane esizingela ngokucathama esibamba inyamazane ngezitho zaso zangaphambili ezinamandla futhi sisebenzise amazinyo aso amade ukuze silume ngokunemba.

izinto ezinhle

Amaqiniso amnandi

I-Smilodon yayinamazinyo amade kakhulu kunanoma yiliphi ikati elinamazinyo amade, efika kumasentimitha angama-28 (amayintshi ayi-11) ubude ezinhlotsheni ezinkulu, i-S. populator.1

Izinsalela ze-Smilodon eziyizinkulungwane zitholakele e-La Brea Tar Pits e-Los Angeles, e-California, okwenza kube irekhodi eliphelele kakhulu lalo hlobo.1

Naphezu kwesidlaliso esithi 'saber-toothed tiger', i-Smilodon ayihlobene kakhulu namahlosi anamuhla. Okhokho bayo bahlukana nomugqa oholela emakati aphilayo eminyakeni eyizigidi ezingu-20 edlule.1

I-Smilodon yayinomsila omfushane, ngokungafani namakati amakhulu anamuhla afana nezingonyama namahlosi, anemisila emide ukuze akwazi ukulinganisela.1

Ososayensi bacabanga ukuthi i-Smilodon kungenzeka yayihlala emaqenjini omphakathi, njengezingonyama zanamuhla, ngoba izinsalela eziningi zohlobo olufanayo zitholakala ndawonye emigodini yetiyela.1

I-Smilodon yashabalala eminyakeni engaba yizi-8,200 edlule, ekupheleni kwenkathi yeqhwa yokugcina, mhlawumbe ngenxa yokushintsha kwesimo sezulu nokulahleka kwezilwane ezinkulu eyayizizingela.1

Izinhlobo ezintathu ezaziwayo ze-Smilodon yilezi: S. gracilis (encane kunazo zonke), S. fatalis (esayizi eliphakathi, evela eNyakatho Melika), kanye ne-S. populator (enkulu kunazo zonke, evela eNingizimu Melika).1

Isithombe sika-Sabre-toothed cat esenziwe nge-AI sokuthi kungenzeka ukuthi wayebukeka kanjani, senziwe yikhompyutha ngokusekelwe kulokho okwaziwa ososayensi. Lokhu kuwukuqagela: isilwane sangempela kungenzeka ukuthi sasibukeka ngokuhlukile, futhi akekho owazi imibala yaso yangempela.

ubuzile

Imibuzo ebuzwa kakhulu mayelana no-Sabre-toothed cat

?Yayinkulu kangakanani i-Smilodon?

Cishe imitha elilodwa (izinyawo ezingama-3.3) ukuphakama ehlombe namamitha ayi-1.75 (izinyawo ezingama-5.7) ubude. Yayinesisindo esiphakathi kwe-160 ne-280 yamakhilogremu (amaphawundi angama-350 kuya kwangama-620). Uhlobo olukhulu kakhulu, i-S. populator, lwalukhulu nakakhulu ngamamitha ayi-1.2 (izinyawo ezingama-3.9) ukuphakama futhi lufinyelela kuma-470 amakhilogremu (amaphawundi ayi-1,040).1 3

?Ingabe i-Smilodon yayikwazi ukubhonga?

Yebo, ososayensi bacabanga ukuthi yayikwazi ukubhonga. Amathambo ayo omphimbo ayefana nalawo amakati anamuhla abhongayo afana nezingonyama.3 4

?I-Smilodon yayidla ini?

?Ingabe i-Smilodon yayihlala emaqenjini?

Ososayensi abaqinisekile, kodwa izinsalela zezilwane ezilimele ezaphola zibonisa ukuthi kungenzeka zazihlala emaqenjini omphakathi njengezingonyama. Nokho, abanye abacwaningi bacabanga ukuthi zazihlala zodwa.1 4 3

?I-Smilodon yayikwazi ukugijima ngesivinini esingakanani?

Akekho owazi ngokuqinisekile, kodwa mhlawumbe yayingeyona umgijimi osheshayo. Yayinomshila omfushane (ngokungafani namahlosi nezinyamazane) kanye nomzimba osindayo, onemisipha, okusikisela ukuthi yayiyisilwane esizingela ngokucathama kunokuba ixoshe inyamazane.4 3

?I-Smilodon yashabalala nini?

Cishe eminyakeni eyizi-8,200 edlule, ekupheleni kwenkathi yeqhwa yokugcina. Yashabalala njengengxenye yokushabalala okukhulu kwezilwane ezinkulu e-Americas.1 4

?I-Smilodon yayihlala kuphi?

Yayihlala eNyakatho Melika naseNingizimu Melika phakathi neNkathi yeqhwa. Izinsalela eziyizinkulungwane zitholakele e-La Brea Tar Pits e-Los Angeles, e-California.1 3

?Kungani i-Smilodon yayinamazinyo amade kangaka?

Amazinyo amade (afika ku-28 cm noma amayintshi angu-11) ayetshelwa ukuba alume ngokunemba nangokujulile emphinjeni noma esiswini senyamazane enkulu. Ayemancane futhi ebuthakathaka, ngakho i-Smilodon yayivula umlomo wayo kakhulu ukuze ingawaphuli.1 3

?Ingabe i-Smilodon iyidinosaur?

Cha, iyisilwane esincelisayo sasendulo nekati elinamazinyo amade. Yaphila isikhathi eside ngemva kokuba ama-dinosaur eseshabalale, phakathi neNkathi yeqhwa.1 3

?Ukuluma kwe-Smilodon kwakunamandla kangakanani?

Ukuluma kwayo kwakunganamandla njengokwengonyama yanamuhla, kodwa yayikwazi ukuvula umlomo wayo kakhulu (ngaphezu kwama-degree angu-120) ukuze ihlabe ngamazinyo ayo amade. Yayisebenzisa izitho zangaphambili ezinamandla ukuze ibambe inyamazane inganyakazi ngenkathi iluma.1

Umchithi wezinganekwane

Inganekwane: Abantu abaningi bacabanga ukuthi i-Smilodon yayiyingwe.

Iqiniso: I-Smilodon yayingeyona ingwe. Yayiyingxenye yeqembu elihlukile, eliphelile lamakati abizwa ngokuthi ama-machairodonts, ayenamazinyo amade kakhulu kanye nomzimba ohlukile.1
