Edmontonia^[1] (lotincha: Edmontonia — zirhli dinozavrlar turkumi, kech boʻr davri nodozavrlar oilasiga mansub. Edmontonia skeletlari Kanada va AQShda topilgan.

Kaltakesak Kanadaning Alberta provinsiyasida joylashgan Edmonton geologik tuzilishi sharafiga nomlangan, uning qoldiqlari birinchi boʻlib topilgan^[2].

Tavsif

Edmontonia balandligi 2 metr va uzunligi 7 metr boʻlib, ogʻirligi 4 tonnaga yaqin boʻlgan oʻtxoʻr dinozavr^[2]. Uning orqa va boshining yuqori qismi suyaklar bilan qoplangan boʻlib, ular dumga yaqinroq boʻlgan tikanlarga oʻxshardi. Toʻrtta eng katta tikanlar kaltakesakning yelkasidan turli yoʻnalishlarda boʻlib, yirtqichlardan himoya yoki kurash vositasi boʻlib xizmat qilgan^[3].

Kashfiyot va qarashlar

Pangolin turi (E. longiceps) birinchi marta 1924-yilda Jorj Paterson tomonidan Morrin qishlogʻi yaqinidagi Horsehoe Canyon geologik shakllanishida kashf etilgan. Biroq, unga ism faqat 1928-yilda Charlz Sternberg tomonidan berilgan. NMC 8531 holotipi qisman skeletdan iborat.

Keyinchalik Texasdagi Aguya geologik qatlamida yana bir tur topildi, u 1930-yilda E. rugosidens nomini oldi. Bosh suyagi tuzilishidagi turlar bilan farq qilganligi sababli, Robert Bakker uni Chassternbergia (Sternberg sharafiga) alohida jins yoki kichik jinsga ajratdi^[4], ammo bu ilmiy hamjamiyatda umumiy eʼtirofga ega emas^[5].

Bugungi kunga qadar maʼlum boʻlgan uchinchi tur, E. australis, faqat topilgan servikal qalqonlardan maʼlum boʻlgan^[6], hozirda Glyptodontopelta (Burns, 2008)^[7] ning sinonimi hisoblanadi.
