Kodwa izinsalela omkhulu futhi omkhulu ifakazela ubukhulu namandla yalezi ezincelisayo. Ngakho, esikhathini esidlule, izilwane ziye ingashintshwa ukuze imvelo, ngisho abantu zohlobo olulodwa angase ashintshwe ushukunyiswa yiwo. Abantu abaningi abanesithakazelo kule ezincelisayo esiyingqayizivele ezifana mastodon. Lesi silwane ivela oda Proboscidea, okuyinto kakhulu lalifana omkhulukazi, kodwa futhi ngaxabana kuzo.

izici mastodons

Namuhla, akukho muntu ucabanga ukuthi mhlawumbe mastodon - kuyinto ngukhokho indlovu ezivamile elikhanyayo. The main esivamile izilwane, yebo - esiqwini, kanye nobukhulu ezinkulukazi eqhathaniswa nezinye izakhamuzi zaseMpumalanga izilwane zasendle. Nokho, kwatholakala ukuthi mastodons babengekho izindlovu eside, okuyinto thina usungabona e-zoo noma kuthelevishini.

Mastodons kubhekwe ezincelisayo yokuqothulwa. Sinenkosi ukufana namanye amalungu oda Proboscidea, kodwa umehluko, nabo bebekhona. Into ebaluleke kakhulu kubo - lena isakhiwo amazinyo. Lezi zilwane ezinkulu Laphezu ukuhlafuna we molars abangu abhanqiwe soskoobraznye izindunduma. Kodwa mammoth nezindlovu phezu molars babe emikhulu transverse, okuyinto ahlukaniswa usimende.

Umsuka kwegama "mastodon"

Kuyathakazelisa ukuthi mastodon - lihunyushwe kwelesiHeberu elithi "ingono", "izinyo". Ngakho-ke, lesi silwane lisuselwa izici isakhi kwamazinyo aso. Qaphela ukuthi kwabanye abantu endaweni umhlathi ongezansi kwakungamadodana eyangaba, okuyinto (ngokososayensi) ashintshwa kusukela amazinyo yesibili.

Mastodons kubhekwe ezidla uhlaza, asikwazanga ukulimaza noma iyiphi umakhelwane, emzini omkhulu ngokuthi "Wildlife". Indishi main kwaba oda Proboscidea eshiya ezihlahla kanye nezihlahla. Nokho, uma ezincelisayo ayesezithendeni, bebengeke ukubulala isilwane seduze isisindo sayo ezinkulukazi ngenxa ukunyakaza abukhali, engazi.

Abesilisa, mastodons

Abanye ososayensi bakholelwa ukuthi mastodon akazange idlule ukukhula sendlovu abavamile. Abesilisa lamabutho Proboscidea ongafinyelela amamitha amathathu ngesikhathi buyabuna. Kuyaphawuleka ukuthi zithanda ukuhlala ngokuhlukana evela emhlambini wezimvu, okungukuthi, izinsikazi futhi izingane zabo. Ukuvuthwa kwabo ngokobulili kufinyelelwe lapho ngineminyaka eyishumi-nanhlanu. Ngokwesilinganiso, mastodons wahlala iminyaka emashumi mathandathu.

Kubalulekile ukuqaphela ukuthi kwakukhona izinhlobo ezahlukene ezincelisayo (US iye echazwe ngenhla), futhi cishe bonke of them ayefana. Kodwa eqinisweni, mastodons zazise-Afrika. Kwaba iminyaka eyizigidi 35 edlule. Ngemva nje kancane kwalokho, bathuthela e-Europe, Asia, eNyakatho naseNingizimu Melika abaye.

amaqiniso ezithakazelisayo

Mastodon (incazelo ongokomfanekiso kuhilela onethonya, into enkulu, ezifana mastodon ibhizinisi mastodon izincwadi), ngokungafani indlovu has eyangaba ku emhlathini yasenhla nemithombo yasenzansi. Ngemva nje kancane kwalokho, i-oda Proboscidea umbono okushintshile, futhi isibalo eyangaba lancipha pair olulodwa. Ososayensi baye bathola ukuthi izilwane saphela cishe iminyaka 10,000 edlule. yohlobo lwazo, kwakunoFakazi abacishe babe ngu amabili.

Enye inguqulo ukushabalala mastodons baba elinegciwane sofuba mammalian. Kodwa ngemva zinyamalala, babengakholwa ukhohlwe. Ososayensi ukutadisha amathambo, eyangaba ka mastodons, okwenza izinto ezintsha kanye sijule umlando esincelisayo esiyingqayizivele. Ngo-2007, i-DNA iye uphenyo isilwane emazinyweni akhe. Abacwaningi bathole ukuthi izinsalela mastodon kwaba kusuka 50 kuya ayizinkulungwane 130. Iminyaka.

Ngakho, mastodon - eliyingqayizivele futhi wafunda ngokugcwele zilwane ezinkulu ababe zamanje emhlabeni izinkulungwane zeminyaka edlule futhi elalibhekwa njengelinye lamazwe izilwane enobungane kakhulu. It is wafakazela ukuthi ngokuhamba kwesikhathi Badla utshani, wakhetha ukuba amacembe ezihlahla kanye nezihlahla, kodwa ngamazinyo azo omkhulu possessed ekuzingeleni okukhulu.
