Ikhanda le-pliosaurus lincane, liphakeme. Ubude bekhanda 2 ngamamitha ayi-2,5. Umlomo ufana nomlomo wengwenya, kuphela ngamazinyo amaningi amakhulu esigaba esingunxantathu. Imihlathi ye-pliosaurus inamandla, ingaghoboza kalula amathambo ohlukunyezwayo. Lapho sesikungene “ezinsikeni zamatshe” ezinjalo, akunakwenzeka ukubalekela.
Ukwakheka komzimba:
Umzimba we-pliosaurus mude futhi mncane, uguqulwe ngokuphelele ukuze unyakaze emanzini. I-pliosaurus yathutha ngosizo lwamaphiko amancanyana afana namawele, cishe amamitha ayi-2. Umsila we-lizard wawumfushane. Ama-pliosaurs afana nezingwenya esimeni somzimba, kepha esikhundleni sama-paws ayenama-pancake namaphini amancanyana nomsila omfishane.
Indlela Yokuphila:
Ama-Plyosaurs ayengashadile. Badla cishe konke ababengakubamba. Ngokuthola usayizi wabo, kungenzeka ukuthi babengenazitha. AbakwaPliosaurus bahanjiswa endaweni yabo hhayi nje kuphela lapho beyofuna ukudla, kodwa futhi bayivikela nezihlobo zayo. Ngaphandle kokungabaza, wahlasela "izivakashi ezingamenyiwe." Abanye abahlaseli basolwandle, ama-plesiosaurs nama-ichthyosaurs, bangaba izisulu zawo. Ngomlomo omkhulu, ipliosaurus ingasiluma ngisho nesilwane esincane ngesigamu. Izinsalela ze-pliosaurus ezitholakele zibonisa ukuthi wayedla no-carrion, okuwukuthi, wadla ama-dinosaurs awela olwandle.
Ukuzalwa okubukhoma:
Yize kunjalo amaPliosaurs ayehlala olwandle, ayezilwane ezihuquzelayo futhi ephefumula umoya. Ngokungafani nezinye ezihuquzelayo ukuthi ziye emhlabathini, azikwazanga ukubeka amaqanda. Ama-Pliosaurs, njengazo zonke ezinye izilwane ezihuquzelayo ezivumelaniswa nobomi basolwandle, azivumelanisa nokuzalwa bukhoma. Ama-Pliosaurs akhula esibelethweni futhi azalwa yizilwane esezakhiwe kakade, futhi azange aqandeke emaqandeni anjengezilwane ezihuquzelayo zomhlaba.
Ukuhlukahluka kwezinhlobo nezinhlobo:
Ekuqaleni ibibheka njengezilwane ezihuquzelayo njengengwenya, ngokungafani ne-plesiosaur enentamo ende. Isihlobo esiseduze kakhulu se-pliosaurus yi-lyopleurodron. Ukwehluka okukhona phakathi kwabo kusakhiwo sude nenani elihlukile lamazinyo. Ngokungafani ne-lyopleurodon, amazinyo e-pliosaurus angunxantathu engxenyeni, hhayi e-conical. Ngaphandle, umehluko phakathi kwabo kungenzeka ungabikhona.
Kunezinhlobo eziningi zama-pliosaurs:
- I-Pliosaurus brachydeirus (uhlobo lwezinhlobo), evela eKimmeridge yaseNgilandi.
- I-Pliosaurus brachyspondylus - nayo evela eKimmeridge yaseNgilandi, yaziwa ngokuba nomzimba wayo ophelele.
- UPliosaurus andrewsi - kusuka eCallovian yaseNgilandi, ifomu elikhulu elinamazinyo azungezwe esigabeni sesiphambano.
- I-Pliosaurus irgisensis - kusuka kungqimba yeVolga yesifunda seSaratov. Ithambo elingaphelele latholakala ngonyaka we-1933 emgodini we-shale wase K.I. Savelyevsky UZhuravlev, ochazwe nguN.I. INovozhilov ngonyaka we-1948. Ekuqaleni yabelwe uhlobo
Ngabe udleni nokuthi iyiphi indlela yokuphila
Bebelokhu bezingela bodwa kusukela bezalwa. Ukuzalwa kwama-dinosaurs amasha kwenzeka emanzini. Babengakhethi ekudleni, badla konke ababekubona. Ngenxa yobukhulu namandla abo, banqoba kunoma iyiphi impi. Babengenazitha zemvelo, ngakho-ke bahlasela kuqala, noma ezinye iziqaqa zazingabafowethu. Ngokuvamile kuhlaselwa ama-pterosaurs angena emanzini, lokhu kufakazelwa iqiniso lokuthi esiswini sezidumbu ezigciniwe zepliosaurs, i-paleontologists ithole izidumbu ezihlukumezekile zalezi dinosaurs ezinamaphiko.
Ikhanda
Isigaxa se-pliosaurus sikhulu kunabo bonke abanye bezilwane abakhona, ubude bawo bungafinyelela ku-2,7 m. Ngenxa yamazinyo amakhulu namazinyo amakhulu, kwakulula ukuluma isisulu ngesigamu nokuchoboza amathambo alo kulolu hlobo. Amandla anjalo awashiyanga thuba lokusinda ngemuva kokulunywa.
