Mayasaurus - dinosaur

Mayazavr ndi ornithopod wamkulu wa banja la duckbill dinosaurs. Omasuliridwa kuchokera ku Latin Maiasaura amatanthauza Lizard-amayi. Cholengedwa chidakhala padziko lapansi kumapeto kwa Cretaceous nthawi 75-65 miliyoni zapitazo. Mayazaurs anali ma dinosaurs akulu kwambiri ndipo amatalika mikono 9, kutalika kwa 3 mita ndi kulemera kwa matani 6.

Tsiku lina, akatswiri a zamankhwala aku America a Jack Horner ndi Robert Mackela adapita ku malo ogulitsira ku Montana ndipo adazindikira zomwe amaganiza kuti ndi mafupa a mwana wa Hadrosaurus. Munali 1978, ndipo kuyambira pamenepo nkhani ya kupezedwa kwa Mayazavrs inayambira. Asayansi anachita chidwi ndi zotsalazo ndipo anathamangira komwe amapezeka.

Mayasaur (lat.Maiasaura)

Zofukulidwa zomwe zidachitika mderalo ndi Horner, Makela ndi anzawo adapeza zotsatira zabwino. Paleontologists adatha kupeza zisa khumi ndi zinayi, ana 31 ndi mazira 42. Zotsatira zake, uku kunali kungoyambira chabe pazotsatira zingapo zabwino. Zaka zingapo pambuyo pake, mu 1984, Horner anapeza mitundu yoposa 10,000 ya a Mayazavrs omwe anali atafa kale. Tsopano ndikosatheka kudziwa chifukwa chake nyamazo zidafa. Ofufuzawo akuti adaphedwa ndi kuphulika kwa phiri.

Mayasaur ana am'madzi chisa.

Umboni wambiri wapezeka kuti a Mayazaurs anali makolo abwino kwambiri. Wamkaziyo adamanga chisa chake ngati mchenga ndi matope ndikuviika ndi zomera zofewa.

Akazi amamanga zisa m'mizere yonse, usiku kuzungulira mozungulira, kumawotha. Zisa zinali pafupifupi mainchesi awiri mulifupi ndi mita 0.9-1.2 kuya. Mayazavra kumaswa kwa dzira anali 35cmlitali okha, koma pofika miyezi iwiri idakula kwambiri. Amayi amadyetsa ana awo mwa kutafuna zakudya za chomera ndi kuwabisira ana awo.

Chiwerengero chochulukirapo cha ma molars, omwe atulukiridwa ndi asayansi, chikutsimikizira kuti a Mayazaurs amadya zakudya zamasamba: masamba ndi mphukira zamera. Zolimba zolimba zolimba zimayala chomera. Mwambiri, a Mayazavras anali azitsamba amtendere.

Malinga ndi miyendo yambiri ya nyama zakale, asayansi atsimikiza kuti a Mayazaurs ankakhala m'gulu lankhosa, ngati ma hadrosaurs ambiri ndipo amayenda ndi miyendo inayi. Nyama zimayenera kusuntha nthawi ndi nthawi kukafunafuna msipu watsopano. Mayasaurs amalimbana ndi zilombo chifukwa chochulukana.

A Mayazavr (lat.Maiasaura peigscorum) ndi am'banja la ma dinosaurs kapena ma hadrosaurs (Hadrosaurus). Amadziwika kuti ndi ma platypus mbali yakumaso, yofanana ndi kamtengo kabakha.

Oimira banja ili anali ma dinosaurs ambiri a Lower Cretaceous. Amakhala ndi zoweta ndipo amadya zakudya zamasamba. Chachikulu kwambiri mwa iwo chinali shantungosaurus, yemwe mafupa ake amapezeka ku China. Chimphona ichi chinali chotalika pafupifupi 13 mita ndi kulemera pafupifupi matani 4.5.

A Mayasaurs amakhala m'chigawo chapakati cha North America.

Nthawi ya moyo wawo imagwirizana ndi nthawi yooneka ngati angiosperms. Ndili ndi nkhalango zowoneka bwino ndi mitengo yayikulu yodzaza ndi udzu wokoma womwe wazungulira. Kuchulukitsidwa kwa chakudya kumeneku kunadzetsa kuchulukitsa msanga kwa mayonesi ndipo ng'ombe zawo zochulukazo mosangalala zimayendayenda mosaneneka ku America yamakono.

Malinga ndi akatswiri a paleont John Johnerer ndi a Bob Mackel atapezeka ku Montana mu 1978, mafupawo adatha kumanganso mafupa a buluzi.

Moyo

Amayasaurs, ngati ma hadrosaurs onse, ankakhala pamagulu akuluakulu. Ubale mkati mwa gululi unamangidwa pamaziko a wolamulira mwamphamvu ndipo, malinga ndi ofufuza, gulu lililonse la abuluzi linkatsogozedwa ndi wamwamuna wamkulu kwambiri komanso wanzeru kwambiri.

Nthawi zonse ankangoyang'anana maso ndi maso. Mphamvu yawo ya kununkhira idapangidwanso bwino. Izi zikuwonetsedwa ndi ma tubules mu chisoti chamfupa, olumikizidwa ndi mphuno ya buluzi. Ma dinosaurs a Herbivorous anali ndi adani ambiri olusa ndipo moyo wa m'gululi unathandiza kupulumuka nthawi zovuta.

Ndi mawonekedwe a zilombo zazikulupo, a Mayasaurs amangodalira mphamvu ndi kulimba kwamiyendo yawo, kuthawa kulikonse komwe maso awo amayang'ana. Omwe adawawonongekera anali akalamba, odwala komanso achichepere kwambiri. Ziwopsezo zazing'ono, gululo lidayendetsa dziko lapansi molimba, ndikuwomba mwamphamvu ndi mchira wamtali wautali.

Mayazavr adadziwika ndi dzina chifukwa cha machitidwe ake apadera a amayi (achi Greek. "Amayi" ndi "buluzi").

Akazi amayikira mazira ndi mainchesi pafupifupi 18 cm pachisa chimodzi. Unali chithaphwi chokhazikitsidwa ndi gulu la akazi kuchokera kumchenga ndi matope, omatidwa ndi udzu wofewa mkati.

Kumeneku kunali kusankha kwanzeru. Pomwe amayi ena amadya kwinakwake chapafupi, ena amateteza mwamphamvu. Panali ambiri a iwo omwe amafuna kudya mazira okoma nthawi imeneyo. Kenako panali kusintha kwa alonda, aliyense anali wosangalala komanso wokondwa.

Usiku, zazikazi zimazungulira mazira, kuziwotha ndi matupi awo. Ofufuza ena anena kuti mwina mayasa anali nyama zamagazi.

Nthawi zina madona achichepere otopa amatha kukhala tulo ndikukhala ovioptor anathamanga kulowera kumapeto kwawo, nkugwira mazira omwe amafunawo ndikubisala m'nkhokwe zapafupi. Ana obadwa nthawi yomweyo.

Anawo anali otalika pafupifupi 30 cm ndipo samatha kuyenda okha. Zikuwonekeratu kuti mwana wotere anali wowopsa kuchoka mchisa, motero amayi osamala amasinthana kunyamula udzu kupita nawo kwa ana awo.

Miyezi iwiri itadutsa, ma mayasaurs ang'ono adakula, adafika kutalika kwa 1-1.5 m, adachoka pachisa ndikulowa m'busayo kukafunafuna msipu watsopano.

Ma dinosaurs achichepere adadya bwino ndipo adakula mwachangu, mpaka kufika 3m kutalika pofika zaka ziwiri. Kenako kukula kwawo kunachepa, amayamba kulemera pang'onopang'ono ndipo pofika nthawi yawo wazaka wazaka 7-8 adafika kutalika kwa 6-7 m.

Kufotokozera

Ma mayasaurs akuluakulu nthawi zambiri amatha kutalika kwa thupi loposa 9 m ndi kulemera kwa matani atatu. Thupi lalikululi lidakongoletsedwa ndi mutu waukulu wokhala ndi kachakudya kakang'ono, kamene kamadzala pakhosi losalala. Khosi silinali lalifupi ndipo silinalole buluzi kufikira masamba akuluakulu. Ndimayenera kukhala wokhutira ndi udzu ndi masamba a zitsamba zotsika.

Kuphimba kwa njira yopangira ma dinosaurs amenewa kunayamba kukhala ngati mulomo wambiri komanso wosalala ndi mphuno yolimba. Nsagwada anali atakhala pansi ndi mano akuthwa, omwe ankathandizira kuti pakhale chakudya.

Zatsogola zidafupikitsidwa ndipo zinafota zinayi. Miyendo yam'mbuyo yamphamvu inali ndi zala zitatu. Mchira wautali, wopatsa mphamvu unathandiza a Mayasaur kukhalabe olimba pamene akuyenda.

Pitani ku mutu wagawo: Mitundu ya ma dinosaurs

Dzinalo la dinosaur la mtundu Mayazaura limatanthawuza "buluzi ndi mayi wabwino." Mayazaur ndi mtundu wa ma dinosaurs mu banja la ma duckbill dinosaurs (hadrosaurids) omwe amakhala kumapeto kwa Cretaceous.

Mbiri yamakono ya mayazaur ikuyamba kuwonongeka mu 1978. Inali nthawi imeneyi pamene akatswiri a maumboni a Jack Horner ndi Robert Makela adapita ku malo ogulitsa zinthu zakale ku Montana, USA, komwe adazindikira mafupa a zomwe amawaganizira kuti anali ana aubongo. Pambuyo pake, adathamanga kupita komwe anapeza.

Ponseponse, a Horner, Makela, ndi gulu la akatswiri opanga ma paleontologists omwe adatsagana nawo adapeza zisa khumi ndi zinayi, ana makumi atatu ndi limodzi, ndi mazira makumi anayi ndi awiri. Koma chimenecho chinali chiyambi chabe. Zaka zingapo pambuyo pake, mu 1984, Horner adapeza dothi lomwe mkati mwake mudali maasaasa oposa 10,000. Malinga ndi mtundu wina, adamwalira pano chifukwa cha kuphulika kwa mapiri, koma mwina sitidzazindikira.

Mayazaur anali mikono 9 kutalika kwake ndipo anali wolemera pafupifupi matani 6. Akazi a Mayazaur anamanga zisa zooneka ngati mitsuko kuchokera ku matope ndi mchenga, kenako ndikuziboola ndi masamba ofewa. Zomera zimapanga zigawo zonse, ndipo mayi a Mayosaurus ankazungulira mazira ake usiku kuti amawotha. Chisa chilichonse chinali chotalika mamita 0.9-1.2 ndi mainchesi awiri.Ndi kukwatula ana a ng'ombe anali okha 35cm, koma pofika miyezi iwiri anali atakulirapo.

Malinga ndi akatswiri ena, mayazaura adadyetsa ana awo, woyamba kutafuna chakudya cham'mera, kenako kuwamwetsa kuti asavutike kulimbana ndi zakudya zolimba.

Mayazaura anali azomera okonda mtendere ndipo ankadya zakudya zamasamba, makamaka zophukira ndi masamba, zomwe zimatsimikizira kupezeka kwa ma molars ambiri. Zinali zoumba zomwe zimapangidwa kuti zizipera chakudya chomera cholimba ndipo zinali zoyenererana ndiichi.

Mayazaura nthawi zambiri amasunthira miyendo inayi ndikuwongolera khola. Akatswiri a Paleontologists adatha kutsimikizira izi pazinthu zingapo zomwe adasiya. Monga abusa ambiri, a Mayasaurs amakhala m'magulu akuluakulu, akusamuka nthawi ndi nthawi kukafunafuna malo atsopano. Zikuwoneka kuti nthawi ndi nthawi anali kugwidwa ndi zilombo, koma nyama zazikulu zamtenderezi zidapulumutsidwa chifukwa kuchuluka kwawo.
