Ikhadi le-Dino No. 1190 kwangu-2 027

Miragaia

Igama lisho ukuthi: “unkulunkulukazi omuhle womhlaba”1

Udla: IzitshaloAma-dino anezikhumba eziqinileLate Jurassic kuya ku-Early Cretaceous

U-Miragaia wayeyisilwane esibizwa nge-stegosaur, i-dinosaur edla izitshalo eneziphangathi nemigogodla emhlane. Wayenentamo ende ngokungajwayelekile, ende kakhulu kunamanye ama-stegosaur amaningi. Lesi silwane esikhulu nesinobungane saphila lapho namuhla kukhona i-Portugal ne-United States enkathini ye-Late Jurassic.1 2

Amaqiniso amnandi

I-Miragaia yayinamathambo entamo okungenani ayi-17, okwayenza yaba nentamo ende kakhulu kune-stegosaur. Ama-stegosaur amaningi ayenamathambo angaphansi kwayi-13.1

Igama elithi Miragaia livela edolobhaneni lapho yatholakala khona, i-Miragaia e-Portugal, futhi lisho nokuthi 'unkulunkulukazi omangalisayo woMhlaba'.1

I-Miragaia yayiyingxenye yeqembu elibizwa ngokuthi i-Dacentrurinae, elihlanganisa isihlobo sayo esiseduze i-Dacentrurus. Ososayensi babevame ukucabanga ukuthi izinsalela eziningi ze-stegosaur ezivela e-Portugal nase-Spain kwakuyi-Dacentrurus, kodwa manje bayazi ukuthi ezinye ziyi-Miragaia.1

Uhlaka lwamathambo olucishe luphelele lwe-Miragaia lutholakale ngo-1959 e-Atouguia da Baleia, e-Peniche, e-Portugal, kodwa aluchazwanga kwaze kwadlula iminyaka eminingi.1

I-Miragaia yayinezici ezifanayo ne-stegosaur yase-Wyoming ebizwa ngokuthi i-Alcovasaurus longispinus, okusikisela ukuthi kwake kwaba nebhuloho lomhlaba elixhuma iNyakatho Melika ne-Iberia (i-Portugal ne-Spain).1

Amapuleti asemhlane we-Miragaia cishe ayetshelwa ukubonisa, kanti imisipha esemsileni wayo (ebizwa ngokuthi i-thagomizer) kungenzeka ukuthi yayiyisikhali sokuzivikela ezilwaneni ezizingelayo.1

Isithombe sika-Miragaia 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.

Umchithi wezinganekwane

Inganekwane: I-Miragaia kwesinye isikhathi icatshangwa ukuthi iwuhlobo lwe-Dacentrurus.

Iqiniso: Ososayensi manje bayavuma ukuthi i-Miragaia iwuhlobo oluhlukile, olusebenzayo, olwehluke kwi-Dacentrurus ngezindlela eziningi, njengentamo yayo ende namathambo omuhlane ahlukile.1

Ochwepheshe bama-dino

Igama lesayensi: Miragaia
Iqanjwe ngu: Mateus et al. 20093
Iqembu: Ama-dino anezikhumba eziqinile
Umndeni / i-clade: Stegosauridae3
Ukuhlukaniswa: Ornithischia > Stegosauria > Thyreophora3
Inkathi yamadwala: 155 kuya ku-121 wezigidi zeminyaka (Kimmeridgian / Barremian)3
Izakhiwo zamatshe: Morrison3
Amazwe: USA3
Izinsalela ezitholiwe: 31 ku-Paleobiology Database3
Ukutholakala: I-Miragaia yaqanjwa ngo-2009 ngu-Octávio Mateus nethimba lakhe, ngokusekelwe kuhlaka lwamathambo olutholakale eduze kwedolobhana lase-Miragaia e-Lourinhã Formation e-Portugal. Isampula eliyisisekelo lihlanganisa ingxenye enkulu yangaphambili yohlaka lwamathambo.1
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi mangaki ngempela amagciwane e-Miragaia ayekhona, nokuthi ngabe ezinye izinsalela ezivela eNyakatho Melika zingezalo hlobo noma ezihlotsheni zalo eziseduze i-Dacentrurus.2
