Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mapeya chinhu chinozivikanwa neshiri (kunyange zvazvo aripowo mune mamwe madinosaurs asingafungidzirwi kuva shiri chaidzo). Anobatsira kutiza, anodzivirira mvura kuti isapisa, uye anoshandiswa pakuratidzira, pakuvharidzira, uye pakuratidza zvinenge zvaitika. Kune marudzi anoverengeka etsinga, imwe neimwe ichishandira zvinangwa zvayo. minhenga zvinhu zvinokura paganda uye zvinongowanika muzvikamu zveganda zvinonzi pterylae. Nzira yokuparadzira nayo mapapiro aya (pterylosis) inoshandiswa pakuronga uye pakuronga. Kurongeka uye kutaridzika kwemapapiro pamuviri, anonzi mapapiro, kunogona kusiyana mukati memhando maererano nezera, chinzvimbo chemagariro, uye bonde. Mapeya anogara achishandurwa; iyo yakajairwa minhenga yeshiri iyo yakashandurwa mushure mekubereka inozivikanwa se "isina-kubereka" minhenga, kana <unk> mune Humphrey-Parkes terminology <unk> "base" minhenga; kubereka minhenga kana misiyano yemhenga yekutanga inozivikanwa pasi peHumphrey-Parkes system se "shanduko" minhenga.
