Spitrasaurus wuxuu lahaa ugu yaraan 60 lafood oo qoorta ah (cervical vertebrae), taas oo ka badan inta badan plesiosaurs-ka Jurassic. Kaliya qaar ka mid ah elasmosaurids-ka Cretaceous ayaa lahaa in ka badan.1
Lafaha qoorta ee Spitrasaurus waxay lahaayeen xariijin muuqata oo dhinaca ah, taas oo ah muuqaal aan lagu arkin plesiosaurs-ka kale ee la xiriira sida Djupedalia ama Kimmerosaurus.1
Laba nooc oo Spitrasaurus ah ayaa la magacaabay: S. wensaasi iyo S. larseni. Waxay ku kala duwan yihiin qaabka lafaha qoorta iyo feeraha.1
Muunaddii ugu horreysay ee Spitrasaurus (S. wensaasi) waxay ahayd mid yar (juvenile), sababtoo ah lafaha dhabarkoodu si buuxda uma wada xirmin. Waxaa lagu kaydiyay dhoobo madow.1
Spitrasaurus wuxuu noolaa qiyaastii 149 ilaa 143 milyan oo sano ka hor, intii lagu jiray xilligii Tithonian ee Jurassic. Lafihiisa waxaa laga helay Slottsmøya Member ee Agardhfjellet Formation.21
Magaca Spitrasaurus wuxuu sharfayaa Spitsbergen Travel, oo ah shirkad safar oo maxalli ah oo gacan ka gaysatay taageeridda cilmi-baarista.1
