I-dinosaur ngobukhulu: bruhathkayosaurus noma ...

I-dinosaur ngobukhulu - ungubani? Lapho abantu beqala ukumba i-dinosaur amathambo (okuyinto kwenzeka okokuqala isikhathi eside kakhulu) yavuka legend udrako elikhulu. AmaGreki lezi amathambo babekholelwa izinsalela namaqhawe akhe - abahlanganyeli kukho ukuvinjezelwa Troy. Ngemva ukuvelela ubuKristu kwafika fashion njengesivikelo amathambo ezilwane akazange usinde kuZamcolo. Futhi eChina ngisho kuchasiselwe ukuphulukisa yabo impahla. Konke kwashintsha ngo yekhulu nesishiyagalolunye, lapho kwakutholakala ukuthi la mathambo - izinsalela izilwane nezakudala. I-dinosaur lokuqala wayechazwa megalosaur - omunye izibankwakazi ezidla ukuthi wahlala iminyaka eyizigidi ezingu-180 edlule. Futhi nakuba igama "megalosaur" uhumusha isibankwa omkhulu, emva zezilwane atholakele esingeqile usayizi eziningi zalo izikhathi.

Ubukhulu of "kakhulu-kakhulu" we Raptors anda lapho kutholakala into entsha ngalinye. I dinosaur ngobukhulu, njengoba kuzolindeleka, ekugcineni kwahlaluka ukuthi ummeleli "ingxenyenamba herbivorous" of izibankwakazi lasendulo. Kodwa brontosaurus, okuyinto ngasekupheleni kwekhulu nesishiyagalolunye isidlulile, "umfanekiso" isibankwa enkulu, eside basked ngenkazimulo. Ngemva kwamashumi eminyaka embalwa Izinto ezintsha abazitholayo ziye ushintshe ukumelwa lwesintu ngezilwane langaphambi kokubhubha komhlaba ngamanzi zenziwe. Yini isimo namuhla?

Isihloko "dinosaur enkulu" manje okungewakho isibankwa nge nzima igama bruhathkayosaurus. Amathambo akhe etholakale 1995 e-India. Nokho, "amathambo" - hhayi ukusho ngeqiniso. Bruhathkayosaurus kwachazwa ithambo elilodwa - lo tibia. Amathambo ka izibankwakazi ezinkulu eminyakeni yamuva awafikanga zokulungisa kwawo i kwezingcezu ezimbalwa ezitholakala. Ngokwesibonelo, omunye Olwa sesihloko "dinosaur ngobukhulu" - amphicoelias - iye yachazwa ngisho lonke ithambo, futhi izingxenye amathambo (!). Njengoba isisekelo kulesi siqeshana, ososayensi bakwazi ukusungula ukuphakama, isisindo kanye nobude isilwane lasendulo - umbuzo omkhulu. Kodwa, kusobala, amasu ezinjalo, nokubekezela okuncane amaphutha, kungenjalo ukuthi bekuyoba "ukubuyisela" izibankwakazi ezingafakwanga ohlwini izilwane lasendulo. Beka lokhu ngokuphathelene umbono ochwepheshe.

Ngakho, ngo-wamanje 2013 abangase sakufanelekela isihloko "dinosaur enkulu?" Eyokuqala isicelo - bruhathkayosaurus. Lokhu giant esingamakhilogremu (at umbono Orthodox) ukuze amathani 240 futhi ube obuphelele kuze kube 44 amamitha. amphicoelias Okwesibili iba esiphezulu isisindo Kulindeleke amathani 155 futhi engu-62 budze. Uma beqhathaniswa "iqhawe" - uhlobo ngizokufa emide emincane: eside kodwa lula. Ngokulinganiswa of course ...

indawo yesithathu kanye indondo lethusi ithola omele mpumalanga yeNingizimu Melika (nakuba ngesikhathi, kubonakala, it is hhayi okwamanje ahlukaniswe esuka ezwekazini afanayo Imininingwane) Argentinosaurus. Wayesebenza kahle ubude 35 amamitha kanye isisindo amathani afinyelela ku 108. endaweni yesine Sauroposeidon, eyayintula ubude 31 amamitha kanye isisindo amathani 60. Kuyinto eyisimanga ngoba iqiniso ukuthi, ngokungafani nezinye eziningi ezinkulu izibankwakazi herbivorous, entanyeni akuyona labetibambile parallel phansi, futhi enwetshiwe phezulu. Siyabonga ukuthi isiphi kalula abheke phansi wesihlanu indlu ifasitela yesimanje. Bese lesithupha. Futhi ekugcineni, ezinkulu ezinhlanu supersaurus uvala. Ubude 34 amamitha kanye isisindo amathani 40 kwenza kuba nevelichkoy ngokumelene isizinda abawinile omkhulu.

Kepha izibankwakazi ezidla, dinosaur ngobukhulu ezidla ngokubona ngazwi linye ngokuthi ososayensi, ke Giganotosaurus, kokuba ukuphakama 7 amamitha kanye isisindo amathani 13. Kungani izibankwakazi ngobukhulu, abameleli ezidla kanye ezidla uhlaza, ngakho ziyahlukahluka ngobukhulu? Iqiniso liwukuthi impilo evamile ezidla kumele zidle enkulu inyama-ukudla. Futhi Ubukhulu esikhulu nesisindo badinga ukuba isekele ukuphila ukushwabadela lenqwaba izilwane. Uma izilwane ezidla ezinye kungaba nenkundla bruhathkayosaurus, bebengayikuba ukubhubhisa wonke ezidla uhlaza, bese sifa yena. Yindlala.
