Meganeura
Meganeura waxa uu ahaa cayayaan weyn oo u eg libaax-badeed (dragonfly) oo noolaa qiyaastii 300 milyan oo sano ka hor. Waxa uu lahaa baalal ballacoodu le'eg yahay shimbir yar, wuxuuna ahaa mid ka mid ah cayayaanka duula ee ugu waaweyn ee abid jiray. Waxa uu ugaarsan jiray cayayaan kale kaymaha furan iyo agagaarka harooyinka.12

Xaqiiqooyin xiiso leh
Baalasha Meganeura waxay ahaayeen qiyaastii 65 ilaa 75 sentimitir (2.1 ilaa 2.5 cagood), kuwaas oo ka weyn libaax-badeed kasta oo maanta nool.1
Indhihiisa waaweyn ee isku dhafan waxay ku kulmi jireen dusha sare ee madaxiisa, taas oo siinaysay aragti aad u wanaagsan si uu uga arko ugaadhsiga cirka.12
Meganeura waxa uu ahaa 'hawker' oo ilaalin jiray meelaha furan iyo dusha sare ee geedaha, ma ahayn mid si degdeg ah ugu duula kaymaha cufan.2
Lugahiisu waxay lahaayeen qodxo waaweyn oo samayn jiray 'dabinnada duula' si uu u qabsado cayayaanka hawada.1
Saynisyahannadu waxay u malaynayaan in Meganeura uu waqti badan ku qaadan jiray fadhiisashada sababtoo ah jidhkiisa weyn ayaa ka dhigay neefsashada mid adag inta lagu jiro duulimaadka.1
Fossilkii ugu horreeyay ee Meganeura waxaa laga helay macdan dhuxul ah oo ku taal Commentry, Faransiiska, sannadkii 1880.1
Hal nooc oo Meganeura ah oo kaliya ayaa maanta loo arkaa mid sax ah: Meganeura monyi.1
Su'aalaha ugu badan ee ku saabsan Meganeura
?Intee in le'eg ayuu ahaa Meganeura?
Meganeura waxa uu lahaa baalal ballacoodu yahay qiyaastii 65 ilaa 75 sentimitir (2.1 ilaa 2.5 cagood) iyo dhererka jidhka oo gaaraya ilaa 43 sentimitir (1.4 cagood). Waxa uu ahaa mid ka mid ah cayayaanka duula ee ugu waaweyn abid.14
?Meganeura ma si degdeg ah ayuu u duuli karay?
Maya, ma samayn karin isbeddel degdeg ah oo jihada ah sida libaax-badeedka casriga ah. Waxa uu ahaa 'hawker' ilaalin jiray meelaha furan iyo dusha sare ee geedaha, isagoo si joogto ah u duulaya halkii uu si qaloocan u duuli lahaa.12
?Maxuu cuni jiray Meganeura?
Meganeura waxa uu ahaa ugaarsade cuni jiray cayayaan kale. Waxa uu isticmaali jiray qodxo waaweyn oo lugahiisa ku yaal si uu u qabsado ugaadhsiga hawada, sida dabin duulaya.14
?Meganeura ma dinosaur baa?
Maya, Meganeura ma aha dinosaur. Waxa uu ahaa cayayaan weyn oo u eg libaax-badeed oo noolaa qiyaastii 300 milyan oo sano ka hor, aad uga hor intaanay dinosaurs-ku soo bixin.1
?Goormuu noolaa Meganeura?
Meganeura waxa uu noolaa xilligii Late Carboniferous, qiyaastii 300 milyan oo sano ka hor.1
?Maxuu Meganeura u weynaa?
Saynisyahannadu waxay u malaynayaan in heerka ogsijiinta sare ee hawada Carboniferous ay laga yaabo inay ka caawisay inuu sidaas u weynaado, laakiin si dhab ah uma hubo. Fikrad kale ayaa ah inaysan jirin ugaarsade duula oo waaweyn waagaas.1
?Meganeura ma lahaa aragti wanaagsan?
Haa, waxa uu lahaa indho waaweyn oo isku dhafan oo ku kulmi jiray dusha sare ee madaxiisa, taas oo siinaysay aragti aad u wanaagsan si uu uga arko ugaadhsiga cirka.12
?Xaggee laga helay Meganeura?
Fossilkii ugu horreeyay ee Meganeura waxaa laga helay macdan dhuxul ah oo ku taal Commentry, Faransiiska, sannadkii 1880.1
?Intee in le'eg ayuu miisaankiisu ahaa Meganeura?
Qiyaasuhu aad bay u kala duwan yihiin, laga bilaabo qiyaastii 18 garaam (0.04 rodol) ilaa 100 ilaa 150 garaam (0.22 ilaa 0.33 rodol). Saynisyahannadu si dhab ah uma hubo miisaanka saxda ah.1
Burinta khuraafaadka
Khuraafaad: Meganeura waxa uu u duuli karay si degdeg ah oo firfircoon sida libaax-badeedka casriga ah.
Runta: Meganeura ma samayn karin leexasho fiiqan sida libaax-badeedka casriga ah sababtoo ah baalashiisu waxay ka maqnaayeen kala-goysyo gaar ah. Waxa uu ahaa ugaarsade gaabis ah oo si simbiriirixasho ah u duula.12
