I-Liopleurodon yayiyenye yezilwanyana zaselwandle ezazihlala kuMbindi Jurassic ukuya kwixesha laLate Jurassic, phakathi kwe-160 kunye ne-155 yezigidi zeminyaka eyadlulayo, kwiilwandle zaseYurophu. Kumelwe ukuba ezona ntlobo zininzi zolu didi zinokufikelela kwiimitha ezi-6,39 ubude. Le carnivore yasemanzini yayiyeyePliosauroidea, eliqela leeplesiosaurs ezinentamo emfutshane. Igama layo, livela kwisiLatini, lithetha "amazinyo agudileyo."
Ngaphakathi kohlobo lweLiopleurodon kukho iindidi ezimbini ezamkelwayo: iLiopleurodon ferox, eyayiyeyona inkulu kwezi zimbini, kunye neLiopleurodon pachydeirus, engaqhelekanga kuneyokuqala. Iintsalela zesi silwanyana zifunyenwe ikakhulu eFransi, eJamani naseNgilani. Okwangoku, awona mathambo apheleleyo afunyenwe kolu didi zezodidi lweLiopleurodon ferox.
Ukufunyanwa kweLiopleurodon
Ngo-1873, uHenri-Émile Sauvage wathiya olu didi lweLiopleurodon emva kokufunyanwa kwe amazinyo amathathu anomlinganiselo weemilimitha ezingama-70. Ngalinye kula mazinyo afunyanwa eFransi kwaye ngokwahlukeneyo, ngoko ke aye abelwe kwiintlobo ezintathu ezahlukeneyo zeLiopleurodon, ekuphela kwento esebenzayo ekugqibeleni yiLiopleurodon ferox.
Iintsalela zezilwanyana zasemanzini ukusuka kwixesha elidlulileyo leJurassic zafunyanwa kwiibhedi zeVolga, eRashiya. Ngomnyaka we-1948, uNovozhilov wabiza igama elithi Liopleurodon rossicus kwaye wayichaza njengelungu lentsapho yasePliosaur. Nangona kunjalo, ikwi-genus Strongylokroptaphus.
Inkcazo yeLiopleurodon
Njengezinye iiplesiosaurs, I-Liopleurodon yayineempiko ezine ezomeleleyo. Ngazo yayiqhutywa emanzini, ngokungafaniyo nezinye iidinosaurs zaselwandle ezinokwenza ngomsila, njenge-Ichtyhosaurus. Uphononongo lwenziwa ngerobhothi malunga nendlela yokudada yezi zirhubuluzi. Lo wabonisa ukuba le ayisiyiyo eyona ndlela isebenzayo, kodwa inika ukukhawuleza okuhle kakhulu. Ekubeni wayezingela elwandle, olu yayiluphawu olwalunqweneleka kakhulu kuye. Kwakhona kwenziwa uphando kukhakhayi lwesi sirhubuluzi sinamandla asemanzini. Kucingelwa ukuba yayinempumlo eyayinokufumanisa ngazo imvelaphi yamavumba athile.
Tamaño
Kuze kube namhlanje, ubungakanani obukhulu beLiopleurodon buhlala bungumbandela ophikisanayo. Isazi ngezidalwa zamandulo (paleontologist) uLB Tarlo ukholelwa ukuba ubude obupheleleyo bepliosaur, kuqukwa neLiopleurodon, bunokuqikelelwa ukusuka kubude bokhakhayi. Ngokutsho kwakhe, ukhakhayi lwezi zirhubuluzi zasemanzini zilingana nesinye kwisixhenxe sobude bomzimba wonke. Olona Khakhayi lude lufunyenwe lwe-L. ferox lunobude be-1,54 yeemitha. Ngokutsho kwe-LB Tarlo, isilwanyana kufuneka silinganise malunga neemitha ezili-10,5 ubude. Nangona kunjalo, izinto ezifunyenweyo malunga ne-Kronosaurus, enye i-genus ye-Pliosaurs, iphosa ukuthandabuza malunga nokuchaneka kwendlela ye-LB Tarlo.
Uphando olongezelelweyo lwe-pliosaur anatomy lukhokelele kwisigqibo sokuba ukhakhayi lwalusinye kwisihlanu kuphela sobude bomzimba wesilwanyana. I-Skeleton ye-L. ferox egcinwe kakuhle iboniswe kwimyuziyam ye-geology kunye ne-paleontology kwiYunivesithi yaseTübingen eJamani. Lo mzekelo unobude obumalunga neemitha ezi-4,5. Omnye umzekelo omdala wolu didi, ovela kwi-Oxford Clay Formation kufuphi ne-Peterborough eNgilani, unokhakhayi ubude be-1,26 yeemitha kunye nobude bayo bubonke buqikelelwa ukuba buzimitha ezi-6,39. Ngoko ke, umntu omdala iLiopleurodon ferox kucingelwa ukuba inobude obupheleleyo obuziimitha ezi-5–7.

Iifosili ezibonisa irhafu mhlawumbi ngaphezulu kwe-15 yeemitha ubude zafunyanwa kwiKimmeridge Clay Formation eNgilani. Nangona kunjalo, lo mzekelo awuzange wabelwa njengowohlobo lweLiopleurodon.
Kukho omnye umfuziselo ongaphelelanga oboniswe kwiYunivesithi yaseOxford iMyuziyam yeMbali yeNdalo eNgilani. Umhlathi wale nto unobude beemitha ezi-2,8. Nangona kunjalo, umhlathi kufuneka ulinganiswe ngaphezu kweemitha ezi-3. Ekuqaleni lo mzekelo wawunikwe uhlobo lweStretosaurus, njengeStretosaurus macromerus. Nangona kunjalo, namhlanje ithathwa njengenxalenye ye-genus Liopleurodon kwaye yabizwa ngokuba yiLiopleurodon macromerus. Kamva yabizwa ngokuba yiPliosaurus macromerus. Ngokuphathelele uhlobo lweStretosaurus, okwangoku ithathwa njengesithethantonye esincinci seLiopleurodon.

Ngonyaka 1999, I-Liopleurodon yaba nenkangeleko kwisiqendu se-miniseries "Ukuhamba needinosaurs", kwiBBC. Apho kubonakala ngathi lirhamncwa elikhulu elinobude obuziimitha ezingama-25. Olu phawu aluhambelani naluphi na uhlobo lwe-Liopleurodon. Le mpazamo inokuba iphenjelelwe kukufunyanwa kwePliosaurs ezinkulu kakhulu, njenge "Arramberi Monster". Kucingelwa ukuba le dayinaso inobude obufikelela kwi-18 leemitha. Nangona kukho ukufana okuthile kunye neLiopleurodon, iintsalela ezifunyenweyo ze "Arramberi Monster" azanelanga ukuyichaza kuyo nayiphi na i-genus.
