Zvinenge mhuka dzose dzine mapfupa emusana dzinoberekana kuburikidza nekuberekana pabonde,soakaita madinosaur. Hunhu hwebonde hwemhuka mhenyu hunowanzova nezviratidzo zvekunze zvakajeka, saka zviri nyore kusiyanisa varume nevakadzi. Semuenzaniso, mapikoko echirume ane minhenga yemuswe yakanaka, shumba dzechirume dzine mazamu marefu, uye elk yechirume ine nyanga uye yakakura kupfuura hadzi. Semhuka yeMesozoic, mapfupa emadinosaur akavigwa.pasiivhu kwemakore emamiriyoni, uye nyama dzakapfavaizvozvinogona kuratidza kuti murume kana mukadziyemadinosaurzvanyangarika, saka zviri zvechokwadizvakaomakusiyanisa rudzi rwemadinosaur! Zvizhinji zvezvisaririra zvakawanikwa mapfupas, uye nyama shoma dzetsandanyama neganda zvinogona kuchengetedzwa. Saka tingatonga sei bonde remadinosaur kubva kumafossil aya?
Chirevo chekutanga chakavakirwa pakuti pane pfupa remedullary here. Mary Schweitzer, nyanzvi yezvepaleontologist paYunivhesiti yeNorth Carolina muUnited States, paakaita ongororo yakadzama ye "Bob" (tyrannosaur fossil), akawana kuti pane pfupa rakakosha mumapfupa efossil, ravakatumidza kuti bone marrow layer. Bone marrow layer inoonekwa panguva yekubereka nekuisa shiri dzechikadzi, uye inonyanya kupa calcium kumazai. Mamiriro akafanana akaonekwawo mumadinosaur akati wandei, uye vaongorori vanogona kuita sarudzo pamusoro pebonde remadinosaur. Muchidzidzo ichi, femur yefossil iyi yedinosaur yakava chinhu chakakosha mukuziva bonde remadinosaur, uye ndiyo zvakare pfupa riri nyore kuziva bonde. Kana pfupa remaburi rakapinda mugomba remedullary repfupa redinosaur, zvinogona kusimbiswa kuti iri idinosaur yechikadzi munguva yekuisa mapfupa. Asi nzira iyi yakakodzera chete kumadinosaur anobhururuka nemadinosaur akagadzirira kubereka kana kuti akabereka, uye asingakwanise kuziva madinosaur asina pamuviri.
Chechipirichirevo ndeyekusiyanisa zvichibva pakakwirira pemadinosaur. Vanochera matongo vaimbofunga kutimurume kana mukadzi inogona kusiyaniswa nemakona emadinosaur, nzira yaive yakakodzera Hadrosaurus. Sekureva kwechiyeroyekusakwana uye chinzvimbo che "korona" yeHadrosaurus, murume kana mukadzi anogona kusiyaniswa. Asi nyanzvi yezvepatholoji inozivikanwa Milner inoramba izvi, WHOsaid, "Kune misiyano mukorona dzemamwe marudzi emadinosaur, asi izvi zvinogona kungofungidzirwa uye kufungidzirwa chete." Pasinei nekutitiri mutsaukopakati Nyanzvi hadzina kukwanisa kuziva kuti ndedzipi nhengo dzemadinosaur crests dziri dzechirume nedzechikadzi.
Chirevo chechitatu ndechekupa mitongo zvichibva pachimiro chemuviri chakasiyana. Hwaro hwacho ndehwekuti mumhuka dzinoyamwisa nezvinokambaira zvipenyu, hono dzinowanzoshandisa chimiro chemuviri chakakosha kukwezva hono. Semuenzaniso, mhino yetsoko inonzi proboscis inoshandiswa nevanhurume kukwezva hono. Mamwe maumbirwo emadinosaur anofungidzirwa kuti anoshandiswa kukwezva honowo. Semuenzaniso, mhino ine minzwa yeTsintaosaurus spinorhinus nekorona yaGuanlong wucaii zvinogona kunge zviri chombo chemashiripiti chinoshandiswa nevanhurume kukwezva hono. Zvisinei, hapana mafossil akakwana ekusimbisa izvi parizvino.
Chirevo chechina ndechekutonga nehukuru hwemuviri. Madhinosaurs akasimba emhando imwe chete anogona kunge aive echirume. Semuenzaniso, matehenya ePachycephalosaurus echirume anoita seanorema kupfuura echikadzi. Asi chidzidzo chinopikisa chirevo ichi, chinoratidza kusiyana kwepabonde mune mamwe marudzi edhinosaurs, kunyanya Tyrannosaurus rex, chakakonzera rusaruro rukuru rwekufunga muvanhu. Makore mazhinji apfuura, bepa rekutsvagisa rakataura kuti T-rex yechikadzi yaive yakakura kupfuura T-rex yechirume. Zvisinei, izvi zvaingobva pazviyero makumi maviri neshanu zvisina kukwana zvemapfupa. Tinoda mapfupa akawanda kuti tinyatsoongorora hunhu hwepabonde hwemadhinosaurs.
Zvakaoma zvikuru kuziva kuti mhuka dzakatsakatika kare dzaiva rudzii kuburikidza nezvinyorwa zvemafossil, asi tsvakiridzo yavo inobatsira zvikuru kune masayendisiti emazuva ano uye ine simba guru pakurarama kwemadinosaur. Zvisinei, kune mienzaniso mishoma kwazvo pasi rose inogona kudzidza zvakarurama nezvehunhu hwemadinosaur, uye kune vaongorori vesainzi vashoma kwazvo muminda ine chekuita nazvo.
