Nhanganyaya yeSmilosuchus

Smilosuchus imhando yakapera yengwena-yakafanana nezvinokambaira zvakararama panguva yeLate Triassic, makore angangoita 230 kusvika 210 miriyoni apfuura. Zvisikwa izvi zvaive chikamu cheboka rezvinokambaira zvinozivikanwa se phytosaurs uye zvaizivikanwa nemhuno dzadzo refu uye semi-mumvura mararamiro. Nepo zvakawanda zvichiri kuzivikanwa nezveSmilosuchus, vaongorori vakawana zvakakosha pamusoro pemaitiro avo ekubereka kuburikidza nekuongorora zvisaririra uye zvidzidzo zvekuenzanisa nezvinokambaira zvemazuva ano.

Fossil rekodhi yeSmilosuchus

Iyo fossil rekodhi yeSmilosuchus ishoma, ine mienzaniso yakawanda inosanganisira akatsemuka skeletal zvisaririra. Zvisinei, vaongorori vematombo vakakwanisa kufukunura zvisaririra zvakawanda zvakachengetedzwa zvinopa nzwisiso inokosha mumigariro uye hunhu hwekubereka hweizvi zvisikwa zvekare. Nokunyatsoongorora zvisaririra izvi, masayendisiti akakwanisa kubatanidza kunzwisisa kuri nani kwegadziriro yokubereka nayo yeSmilosuchus.

Nhengo dzekubereka muSmilosuchus

Kuongororwa kwefossilized specimens kwakaratidza kuvepo kwenhengo dzekubereka muSmilosuchus. Mienzaniso yechirume ine ma testes akagadzirwa zvakanaka, zvichiratidza kugona kwavo kugadzira urume. Madzimai, kune rumwe rutivi, anoratidza humbowo hwemaoviducts, zvichiratidza kugona kwavo kugadzira mazai uye kutakura. Izvi zvakawanikwa zvinoratidza kuti Smilosuchus aive nevarume vakasiyana, hunhu hunowanzoonekwa muzvinokambaira.

Kubatana maitiro eSmilosuchus

Maitiro ekusangana kweSmilosuchus anoramba achingofungidzira nekuda kwehushoma humbowo hwefossil huripo. Nekudaro, zvichibva pakuenzanisa nezvinokambaira zvemazuva ano, zvinotendwa kuti Smilosuchus akabatanidzwa mukusangana kwemukati. Murume Smilosuchus angangodaro akashandisa mhino dzake kuti abate pamukadzi panguva yekubatana, maitiro anoonekwa muzvinokambaira zvakawanda zvemazuva ano.

Nesting tsika dzeSmilosuchus

Kunyange pasina humbowo hwakananga hwenzvimbo dzekugara hwawanikwa, kuvepo kwemazai akapfava mune vamwe vanhu vane fossil kunoratidza kuti Smilosuchus inogona kunge yakaisa mazai munzvimbo dzekugara. Nzvimbo dzekuvakira idzi dzinofungidzirwa kuti dzaiva pedyo nemvura, zvichiita kuti pave nenzvimbo yakakodzera yokuchengeta.

Kuchengeta kwevabereki muSmilosuchus

Ukuru hwekutarisira kwevabereki muSmilosuchus hausati hwanyatsozivikanwa. Zvisinei, kuvapo kwemazai akapfava kunoratidza kuti kumwe kuchengetwa kwevabereki kungave kwaivapo. Zvinogoneka kuti hono kana hadzi yaichengeta dendere racho uye yaidzivirira mazai acho kusvikira achochonya.

Anogona kubereka nzira dzeSmilosuchus

Zvichienderana nekuongororwa kwemazai efossilized, zvinotendwa kuti Smilosuchus akashandisa zano rekukandira mazai akawanda mune rimwe clutch. Iyi nzira yekubereka yakajairika pakati pezvinokambaira uye inobvumira mikana mikuru yekupona kwevana. Pamusoro pezvo, kuvapo kwemazai akapfava-akapfava kunoratidza kuti Smilosuchus anogona kunge akaviga mazai avo mu substrate kuti ape kudzivirira nekudzivirira.

Smilosuchus mating rituals

Iwo chaiwo iwo maSmilosuchus mating tsika haazivikanwe, asi vaongorori vanofungidzira kuti izvi zvinokambaira zvinogona kunge zvakapinda mukuratidzira kwakadzama kwekupfimbana kukwezva vakaroorana. Aya maratidziro anogona kunge aisanganisira zviratidzo zvekuona, senge posturing kana coloration, pamwe nemanzwi kana masaini anonhuwa.

Kudanana kunoratidza muSmilosuchus

Kuratidzira kwekudanana muSmilosuchus kungangove kwaisanganisira zviratidzo zvekuona, sekufamba kwemuviri uye kuchinja kwemavara. Murume Smilosuchus angave akaratidza simba ravo uye simba kuburikidza nekuratidzira kwehasha, nepo vakadzi vangave vakaratidza maitiro ekugamuchira kuratidza kuwanikwa kwavo kwekusangana.

Smilosuchus mazai-kuisa maitiro

Iyo fossil rekodhi inoratidza kuti Smilosuchus yakaisa mazai mumakumbo, asi maitiro chaiwo ekuisa zai achiri asina chokwadi. Zvinokwanisika kuti Smilosuchus akaisa mazai avo mumatendere evanhu, umo vakadzi vakati wandei vakakandira mazai avo pamwechete, kana kuti vangave vakaisa matendere ega. Kumwe kutsvagurudza uye zvakawanikwa zvinodikanwa kuti upe mhinduro yakanyatsojeka.

Incubation nguva yeSmilosuchus mazai

Kuona iyo chaiyo incubation nguva yeSmilosuchus mazai kunonetsa nekuda kwehushoma humbowo hwefossil. Nekudaro, ongororo dzekuenzanisa nezvinokambaira zvemazuva ano dzinoratidza kuti incubation nguva ingangoita mavhiki akati wandei kusvika kumwedzi yakati wandei, zvichienderana nemamiriro ekunze akadai sekushisa uye hunyoro.

Hatching uye kusimudzira kwekutanga muSmilosuchus

Iko kunyungudutswa uye kukura kwekutanga kweSmilosuchus kuchiri kusanzwisiswa. Zvisinei, kuvapo kwevana vakakura zvakanaka mukati mezvimwe zvisaririra zvinoratidza kuti Smilosuchus inogona kunge yakaratidza pwere isati yakwana, inokwanisa kufamba yakazvimirira nguva pfupi mushure mekuchechenywa. Izvi zvaizoenderana nemaitiro ekubereka anoonekwa muzvinokambaira zvemazuva ano.

Mukupedzisa, nepo ruzivo rwedu rwekubereka kweSmilosuchus ruchiri rwakaganhurirwa, kunzverwa kwechinyorwa chayo chezvisaririra kwakajekesa mativi akasiana-siana egadziriro yayo yokubereka nayo. Kubva pakuvapo kwenhengo dzekuberekesa kusvika kune zvinogona kuita tsika dzekusvirana nekuita matendere, vatsvakurudzi vakagadzira pamwe chete kunzwisisa kwekutanga kwekuti mhuka dzekare idzi dzaiberekana sei nekuchengeta vana vadzo. Nekudaro, kumwe kutsvagisa uye zvakawanwa zvinodiwa kuti uwane mamwe mashoko pamusoro pemaitiro anonakidza ekubereka aSmilosuchus.
