Metashastasaurus
I-Metashastasaurus yayiyisilwane esikhulu sasolwandle esayibhukuda ezilwandle ngesikhathi se-Late Triassic, eminyakeni ecishe ibe yizigidi ezingama-227 kuya kwezingama-205 edlule. Kwakungesilo isilwane esihuquzelayo (dinosaur), kodwa kwakuwuhlobo lwe-ichthyosaur, enomzimba ofana nowehlengethe nomlomo omude. Yayihlala ezilwandle eduze kwalapho okuyindawo yase-British Columbia, e-Canada namuhla.12

Amaqiniso amnandi
I-Metashastasaurus yaqanjwa okokuqala ngonyaka we-2001 ngososayensi u-Nicholls no-Manabe.1
Uhlaka lwayo lwamathambo lufana kakhulu nezinye izinhlobo ze-shastasaurid ichthyosaur, kodwa ithambo lehlombe nethambo lomlenze (i-fibula) zinomumo ohlukile.2
Ukhakhayi lwayo lunamathambo amakhulu amise okwedayimane ngaphambili (amathambo phezulu ekhanda) angena ezimbotsheni zokuvuleka kukhakhayi.2
Yayinamathambo amane esihlakala (wrist bones) neminwe emine emlenzeni wangaphambili, okukhombisa ukuthi ukwakhiwa kabusha kwangaphambili kwakusekelwe ezintweni ezingaphelele.2
I-Metashastasaurus yayihlala endaweni yasolwandle futhi yayibhukuda ngenkuthalo emanzini avulekile.1
Yayizala amaphuphu aphilayo, njengamanye ama-ichthyosaur, kunokuba izale amaqanda.1
Buza u-Rex ngo-Metashastasaurus
Rex uphendula imibuzo mayelana naleli khasi kuphela. Imibuzo engu-10 ngenyanga.
Rex uyi-AI futhi angenza amaphutha. Usebenza kumaseva ase-EU futhi imibuzo ayilokothi ilondolozwe. Ungalokothi uthayiphe igama lakho noma ezinye izinto zakho.
Umchithi wezinganekwane
Inganekwane: Abanye abantu bacabanga ukuthi i-Metashastasaurus yayiyisilwane esihuquzelayo (dinosaur) ngoba yayiphila ngesikhathi esifanayo nezilwane ezinjalo.
Iqiniso: I-Metashastasaurus yayiyi-ichthyosaur, isilwane sasolwandle, hhayi isilwane esihuquzelayo (dinosaur). Ama-ichthyosaur ayehlala olwandle futhi enemizimba efana nezinhlanzi, kanti izilwane ezinjalo (dinosaurs) zaziyizilwane zasemhlabathini.1

- Ukutholakala
- I-Metashastasaurus yaqanjwa ngu-Nicholls no-Manabe ngonyaka we-2001 ngemuva kokuba befunde izinsalela ezintsha ezivela e-Pink Mountain, e-British Columbia. Lezi zinsalela zakhombisa ukuthi uhlobo olwalubizwa ngokuthi i-Shastasaurus neoscapularis lwaluhlukile ngokwanele ukuba lubekwe ohlotsheni olusha.2
- Kusaphikiswana ngakho
- Ososayensi basaphikisana ngokuthi ngabe uhlobo lwe-Shastasaurus lusebenza yini, ngoba uhlobo lwayo lusekelwe ezinsaleleni ezimbi. I-Metashastasaurus yadalwa ukusiza ukucacisa lokhu, kodwa ubudlelwano phakathi kwalezi zinhlobo ze-ichthyosaur abukacaci ngokuphelele.2
