Ngabe udleni nokuthi iyiphi indlela yokuphila
Ukuzingela akuzange kwenzeke emaphaketheni, njengakwizinyamazane eziningi, kodwa kusizodwa. Wayengazingela ama-pterosaurs kanye nemithi yesikhathi ngaleso sikhathi, elinde izisulu zakhe endaweni yokuqamekela. Imvamisa, akenzanga ukuthi ohlukunyezwe alinde isikhathi eside ngokufa kwakhe, wazama ukuthatha impilo yakhe masinyane, ngoba lokhu waluma intamo.
Kepha ngaphandle kwakho konke, ukudla okuyinhloko bekubandakanya izinhlanzi, kwesinye isikhathi kuze kuhlasele oshaka, izimfudu kanye nezingwenya - ungene echibini futhi alinde nethuba lokuhlasela nokudla izinhlanzi eziningi ngangokunokwenzeka. Akumangalisi ukuthi ubukeka njengezingwenya, njengabo, wayethanda ukuhlala emanzini, ajabulele ukuthula bese kuphela eseqala ukuzingela. Ngezikhathi ezithile, ngaphezu kwezinhlanzi nenye i-salmon, wayedla u-carrion ohlukahlukene.
Imininingwane yesakhiwo somzimba
Wayenobukhulu obukhulu nesigaxa esinamandla. Ngisho nemidondoshiya edumile njenge-giototosaurus neTirannosaurus ayikwazanga ukufinyelela osayizi onjalo; ungumbusi omkhulu kunabo bonke abadayisi basemhlabeni. Njengoba kubonakala esithombeni, izindunduma eziphakeme, ezazimbozwe ngesikhumba, zigqitshwa emhlanjini we-spinosaurus. Eduze nendawo, mude kunalawo asezansi yentamo nomsila. Ispike eside kunazo zonke sasingamamitha ayi-2, ukunemba - 1,8 m. “I-Sail” yayisetshenziselwa ukuheha abantu besifazane futhi yayiyithuluzi elibonisa ukwelashwa.
Ubukhulu
Ngokude, abantu abadala bafinyelela ku-15 - 18m, ama-dinosaurs asemasha nawo ayemakhulu impela - 12m
Ekuphakameni kwe-4 - 6m (kuya ngokuthi i-zavr imile imilenze emingaki, 4 no-2, ngokulandelana)
Isisindo somzimba - kusuka ku-9 kuye ku-11.5t (umuntu omdala), u-5t - zavr osemncane
Ikhanda
Ubuso besixoka bebufana nobuso bezingwenya zamanje. Isigaxa sasisikhulu, kepha sincishisiwe ekuqaleni komhlathi, owawunamazinyo abukhali ngokungenangqondo (angaluma noma yisiphi isikhumba). Kwakunamazinyo ambalwa uma kuqhathaniswa: ukuqala komhlathi ongaphezulu nangaphansi wayenamazinyo amade ayi-7, kuthi ngemuva kwawo - u-12 - 13 ohlangothini ngalunye lwaluncane, kepha lubukhali ngokulinganayo.
Izimbotshana
Kuze kube manje, izinsalela ezigcwele zama-paws abo azikatholakali, ososayensi bekufanele basebenze isikhathi eside ukuphinda babonakale ukubukeka kwabo. Kuyaziwa nje ukuthi bekukhona aba-4 kubona kanti ngamunye wayenezinqaqa ezibukhali. Imilenze yangemuva yinde kunokwangaphambili, kepha ayihlukile kakhulu ngamandla, i.e. babenamandla amakhulu okubamba isisindo somzimba ngezinyawo futhi baklebhule izisulu zabo.
