Merriamosaurus

Igama lisho ukuthi: “Isibankwa sika-Merriam”1

Udla: InyamaAma-ichthyosaurEarly Triassic kuya ku-Middle TriassicAkuyona i-dinosaur ngempela

I-Merriamosaurus kwakuyisilwane esihuquzelayo sasolwandle sasendulo esasibhukuda ezilwandle ezizungeze i-Svalbard namuhla, e-Norway, cishe eminyakeni eyizigidi ezingama-248 edlule. Kwakuwuhlobo lwe-ichthyosaur, isilwane esihuquzelayo esifana nehlengethwa esasiphefumula umoya kodwa sihlala emanzini. I-Merriamosaurus yayiyisilwane esizingelayo esiphezulu, esasizingela izinhlanzi nezinye izidalwa zasolwandle.1 2

Iqiniso elimnandi: lesi silwane sasolwandle sasibhukuda ngenkathi ama-dinosaur ehamba emhlabathini. Wonke umuntu ubabiza ngama-dino, kodwa ayeyigatsha elihlukile lezilwane ezihuquzelayo.

Amaqiniso amnandi

I-Merriamosaurus yaqanjwa ngonyaka ka-2002 ososayensi u-Maisch no-Matzke.1

Yaphila ngesikhathi sesigaba se-Spathian se-Early Triassic, cishe eminyakeni eyizigidi ezingama-248 kuya kwezingama-247 edlule.1

I-Merriamosaurus yayiyi-ichthyosaur eyisisekelo enezimpiko ezinde, okusho ukuthi yayinezimpiko ezinde futhi yayiyisihlobo sakuqala sama-ichthyosaur athuthuke kakhulu.2

Yayiyeyona ethuthuke kakhulu kuma-ichthyosaur ase-Lower Triassic eyayaziwa ngesikhathi ichazwa.2

I-Merriamosaurus yayizala amaphuphu aphilayo, njengamanye ama-ichthyosaur amaningi.1

Izinsalela zayo zatholakala e-Sticky Keep Formation e-Spitsbergen.1 2

Isithombe sika-Merriamosaurus esenziwe nge-AI sokuthi kungenzeka ukuthi wayebukeka kanjani, senziwe yikhompyutha ngokusekelwe kulokho okwaziwa ososayensi. Lokhu kuwukuqagela: isilwane sangempela kungenzeka ukuthi sasibukeka ngokuhlukile, futhi akekho owazi imibala yaso yangempela.

Buza u-Rex ngo-Merriamosaurus

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.

Ochwepheshe bama-dino

Igama lesayensi: Merriamosaurus
Iqanjwe ngu: Maisch and Matzke 20023
Iqembu: Ama-ichthyosaur
Umndeni / i-clade: Merriamosauridae3
Ukuhlukaniswa: Ichthyosauria > Ichthyosauromorpha3
Inkathi yamadwala: 249 kuya ku-247 wezigidi zeminyaka ()3
Izakhiwo zamatshe: Sticky Keep3
Amazwe: Svalbard3
Izinsalela ezitholiwe: 1 ku-Paleobiology Database3
Ukutholakala: I-Merriamosaurus yaqala ukuchazwa ngamathambo ahlukene, kodwa kamuva kwatholakala amathambo aphelele kakhudlwana e-Sticky Keep Formation e-Spitsbergen. Yaqanjwa ngu-Michael W. Maisch no-Andreas T. Matzke ngonyaka ka-2002.1 2
Kusaphikiswana ngakho: Ososayensi abaqiniseki ngobukhulu obuqondile be-Merriamosaurus ngoba kutholakale amathambo ayincenye kuphela.2

Yonke imininingwane ekuleli khasi inenombolo ekhomba umthombo wayo. Uma kukhona esikwenze kabi, siyaxolisa, singabalandeli bama-dino, hhayi iphephabhuku lesayensi. Sitshele ku-[email protected] futhi sizokulungisa.

Rex ulambile! I-Dino Wiki iphrojekthi kababa wendodana yakhe ethanda ama-dino, imahhala ngaphandle kwezikhangiso nezilandeleli. Abantu abadala bangaphakela u-Rex ukudla okulula ukuze basize ukuyigcina iku-inthanethi.Phakela u-Rex
