Megacephalosaurus
Megacephalosaurus wuxuu ahaa plesiosaur weyn oo qoortiisu gaaban tahay, kaas oo ku dabaalan jiray badweyntii hore ee kala qaybisay Waqooyiga Ameerika laba qaybood. Wuxuu lahaa madax aad u weyn, kaas oo ahaa kii ugu weynaa ee laga helo plesiosaur kasta oo qaaraddaas laga helay, wuxuuna u isticmaali jiray afkiisa dheer inuu ku qabto ugaadh yar.1

Xaqiiqooyin xiiso leh
Megacephalosaurus wuxuu ahaa mid ka mid ah pliosaurs-kii ugu dambeeyay, wuxuuna noolaa qiyaastii 94 ilaa 93 milyan oo sano ka hor intii lagu jiray xilligii Turonian ee Late Cretaceous.1
Madaxiisu wuxuu gaadhayay ilaa 1.75 mitir (5.7 feet) dherer ahaan, taas oo ka dhigaysa madaxa ugu weyn ee plesiosaur kasta oo laga yaqaan Waqooyiga Ameerika.1
Ilkuhu waxay lahaayeen xariijimo dhaadheer oo dhuuban oo loo yaqaan apicobasal ridges kuwaas oo ka caawin jiray inay qabtaan oo ay dalooliyaan ugaadha simbiriirixan.1
Wuxuu badweynta kula noolaa nibiriyo ay ka mid yihiin Cretoxyrhina iyo Squalicorax, iyo sidoo kale xamaaratada kale ee badda sida mosasaurs iyo qoolleyda badda.1
Fossilkii ugu horreeyay waxaa la helay 1950-kii waxaana markii hore loo maleeyay inay ka tirsan yihiin pliosaur kale oo la yidhaahdo Brachauchenius lucasi.1
Ilaa sanadkii 2013 saynisyahannadu ma ogaan in fossilladu ay ka yimaadeen xayawaan cusub oo gaar ah, waxayna u bixiyeen Megacephalosaurus.1
Su'aalaha ugu badan ee ku saabsan Megacephalosaurus
?Intee in leeg ayuu ahaa Megacephalosaurus?
Wuxuu ahaa mid ka mid ah xamaaratada badda ee ugu waaweyn xilligiisii, waxaana lagu qiyaasay inuu ahaa 6 ilaa 9 m (20 ilaa 30 ft) dherer ahaan. Madaxiisa oo keliya ayaa gaadhi karay 1.75 m (5.7 ft) dherer ahaan.1
?Maxuu cuni jiray Megacephalosaurus?
Wuxuu u badnaa inuu cuno ugaadh yar, sababtoo ah wuxuu lahaa af dheer iyo ilko dhammaantood isku cabbir ahaa. Ilkihiisu waxay lahaayeen xariijimo ka caawin jiray inay qabtaan oo ay dalooliyaan xayawaanka simbiriirixan.12
?Goorma ayuu noolaa Megacephalosaurus?
Wuxuu noolaa qiyaastii 94 ilaa 93 milyan oo sano ka hor, intii lagu jiray xilligii Turonian ee Late Cretaceous. Wuxuu ka mid ahaa pliosaurs-kii ugu dambeeyay.1
?Megacephalosaurus ma dinosaur baa?
Maya, ma aha dinosaur. Waa plesiosaur, nooc ka mid ah xamaaratada badda oo ku noolaa badweynta isla wakhtigii dinosaurs-ka.1

- Saynisyahannadu weli way ka doodayaan sida pliosaurs-ka ugu dambeeyay ee brachauchenine, oo ay ku jiraan Megacephalosaurus, ay isugu xidhan yihiin iyo waxa ay ilkahoodu nooga sheegayaan horumarkooda.2
