Scalamagnus
I-Scalamagnus yayiyisilwane esihuquzelayo sasolwandle esincane nesibhukuda ngokushesha, esayiphila olwandle olufudumele nolungashoni olwalukade lumboze i-North America. Yayinomlomo omude ogcwele amazinyo abukhali futhi yayisebenzisa izimpiko zayo ezine ukubhukuda ngokushesha ilandela izinhlanzi nezinkalankala.12
Yaphila nini?
Yayinkulu kangakanani?
Yayinde kangakanani?
inde njengezinja ezi-3 kusukela ekhaleni kuya emsileni🍌inde njengobhanana abangu-18 belandelana🏊ingabhukuda ubude bechibi elikhulu (50 m) ngemizuzwana engu-6.4Yayinkulu kangakanani i-Scalamagnus uma uqhathaniswa NAWE?
Izibalo nje kusiphequluli sakho. Akukho okugcinwayo noma okuthunyelwa ndawo.
Yayishesha kangakanani?
Amaqiniso amnandi
I-Scalamagnus ekuqaleni yayicabangelwa ukuthi iwuhlobo lwe-Dolichorhynchops, kodwa ososayensi kamuva bayinika igama layo ngonyaka ka-2023.1
Uhlobo olulodwa lwe-Scalamagnus lwatholakala lunamatshe esisu angu-289 (gastroliths), okuyinto engajwayelekile kakhulu kuleli qembu lama-plesiosaurs.1
Amatshe esisu ayenesisindo esicishe sibe amagremu angu-518 esewonke, futhi iningi lawo lalingaphansi kwamagremu angu-2.1
Yaphila eminyakeni ecishe ibe yizigidi ezingama-93 kuya kwezingama-91 edlule, phakathi nesigaba sokuqala se-Turonian se-Late Cretaceous.1
I-Scalamagnus yayiyi-polycotylid plesiosaur, iqembu elaziwa ngokuba nentamo emfishane namakhanda amakhulu, ngokungafani nama-plesiosaurs anentamo ende.1
Igama elithi Scalamagnus lihlonipha i-Grand Staircase-Escalante National Monument e-Utah, lapho izinsalela zayo zambiwa khona.1

- Kusaphikiswana ngakho
- Ososayensi abaqiniseki ukuthi kungani i-Scalamagnus yayinamatshe amaningi esiswini, ngoba iningi lamanye ama-polycotylids ayengenawo.1
