Masayendisiti muGanzhou City, kuchamhembe kweChina kuRuwa rweJiangxi, akawana chinjo huru. Vakawana mapfupa edhinaso, iro rakanga rakagara padendere raro rine mazai akapwanyika.
Dinosaur, inozivikanwa se oviraptorosaur (oviraptor), chikamu cheboka reshiri-se theropod dinosaurs yakabudirira muCretaceous Period (makore 145 kusvika ku66 apfuura).
Mafossils echikuru oviraptor uye mazai embryonic akaverengerwa kumakore anosvika mamirioni makumi manomwe apfuura. Aka ndekekutanga vatsvakurudzi kuwana dinosaur risiri shiri rakazorora padendere rakapwanyika ramazai, iro richine mwana mukati!
Fossil iri mubvunzo ndeye munhu mukuru ane makore ane mamiriyoni makumi manomwe oviraptorid theropod dinosaur akagara pamusoro pedendere remazai ayo akaomeswa. Mazai akawanda (angangoita matatu ane embryo) anooneka, sezvakaita maoko emunhu mukuru, pelvis, makumbo neshure, uye chikamu chemuswe. (Shandong Bi yeIndiana University yePennsylvania)
Masayendisiti anoti kudii nezvekuwanikwa kwacho?
Munyori mukuru wechidzidzo ichi, Dr. Shundong Bi veCentre for Vertebrate Evolutionary Biology, Institute of Palaeontology, Yunnan University, China, neDepartment of Biology, Indiana University of Pennsylvania, USA, vakataura mupepanhau. “Madhinairosi akachengetwa pamatendere awo haawanzowanikwi, uye ndizvo zvakaitawo mazai ezvisaririra. Aka ndekekutanga kuti dinosaur risiri remundege riwanikwe, rakagara padendere ramazai anochengetedza mazai ari mudumbu, mumuenzaniso mumwe unoshamisa.”
Kunyange zvazvo masayendisiti akamboona ma<em>ovirapta akura pamatendere awo ane mazai kare, aka ndiko kekutanga kuti mazai anowanikwa mukati memazai. Mumwe munyori wezvidzidzo Dr. Lamanna, nyanzvi yezvakaitika kare kubva kuCarnegie Museum of Natural History, USA, anotsanangura: “Urwu rudzi rwokuwanwa, chaizvoizvo, hunhu hwefossilized, ndihwo husingawanzowanikwi mumadhainari. Kunyangwe maoviraptorid mashoma akura akambowanikwa pamatendere emazai avo, hapana mazai akambowanikwa mukati memazai iwayo. "
Dr. Xu, muongorori weInstitute of Vertebrate Paleontology and Paleoanthropology muBeijing, China, uye mumwe wevanyori veongororo iyi, anotenda kuti kuwanikwa uku kusingawanzo kuwanikwa kune hupfumi hweruzivo. "Zvinoshamisa kufunga kuti ingani ruzivo rwebiology rwakatorwa mufossil iyi chete." Dr. Xu anoti, "Tichave tichidzidza kubva kumuenzaniso uyu kwemakore mazhinji ari kuuya."
Mazai efossil akanga ava kuda kuchochonywa!
Masayendisiti akawana skeleton yemunhu mukuru ane matombo mudumbu. Uyu muenzaniso we gastroliths. "matombo emudumbu," iyo yakanga yadyiwa nechisikwa ichi kuibatsira kugaya zvokudya zvayo. Ndiwo zvakare chiitiko chekutanga chegastroliths isingaverengeki yakawanikwa mune oviraptorid, iyo masayendisiti anonzwa kuti inogona kubatsira kujekesa chikafu chedinosaurs.
Muchimiro chekudzivirira kana chekudzivirira, dinosaur yakawanwa yakarereka pamusoro pedendere rine mazai anokwana makumi maviri nemana. Izvi zvinoratidza kuti dinosaur rakaparara richifunganya kana kudzivirira vana varo.
Nekudaro, vaongorori pavakashandisa oxygen isotope ongororo pamazai, vakawana kuti akange akaiswa pakakwirira, seshiri-setembiricha seshiri, zvichikweretesa dzidziso yekuti mukuru akaparara achifurira dendere rake.
Anosvika manomwe emazai efossilized anga achiri nema "oviraptorid embryos" mukati mawo. Vesainzi vanodavira kuti mamwe mazai akanga ari pamucheto wekuchechenywa zvichienderana nekugadzirwa kwekwakabva. Maererano naDr. Lamanna, "Dinosaur uyu aive mubereki ane hanya akazopa hupenyu hwayo achirera vana vayo."
