\nSpecia, denumit\u0103 Istiorachis macarthurae, a fost descris\u0103 de dr. Jeremy Lockwood, doctorand la Universitatea din Portsmouth \u015fi la Muzeul de Istorie Natural\u0103 din Londra. Numele combin\u0103 termenul \u201esail spine\u201d (coloan\u0103 cu \u201evel\u0103\u201d) \u015fi o trimitere la Ellen MacArthur, navigatoarea britanic\u0103 ce a stabilit \u00een 2005 recordul mondial pentru cea mai rapid\u0103 c\u0103l\u0103torie solitar\u0103, f\u0103r\u0103 oprire, \u00een jurul lumii.<\/p>\n
\nFosilele, dat\u00e2nd de aproximativ 125 de milioane de ani, au fost ini\u0163ial atribuite uneia dintre cele dou\u0103 specii deja cunoscute de pe Insula Wight. Analiza comparativ\u0103 a oaselor conservate a ar\u0103tat \u00eens\u0103 c\u0103 acestea apar\u0163ineau unei specii distincte. \u201eSpre deosebire de celelalte, acest exemplar avea spini neurali mult mai lungi, ceea ce era extrem de neobi\u015fnuit\u201d, a explicat Lockwood, potrivit The Guardian.<\/p>\n
\nCercet\u0103torii cred c\u0103 dinozaurul poseda o vel\u0103 pronun\u0163at\u0103, folosit\u0103 cel mai probabil pentru semnalizare vizual\u0103, \u00een special pentru atragerea partenerilor sau intimidarea rivalilor. \u201eEvolu\u0163ia pare s\u0103 favorizeze uneori extravagan\u0163a \u00een detrimentul aspectelor practice. \u00cen cazul Istiorachis, cel mai probabil aceast\u0103 vel\u0103 era parte dintr-un afi\u015faj sexual\u201d, a precizat Lockwood, men\u0163ion\u00e2nd asem\u0103n\u0103ri cu reptilele moderne.<\/p>\n
\nProf. Susannah Maidment, de la Muzeul de Istorie Natural\u0103, a salutat descoperirea, subliniind importan\u0163a colec\u0163iilor muzeale: \u201eStudiul atent al fosilelor p\u0103strate de ani \u00een colec\u0163ii a readus la via\u0163\u0103 dinozaurii iguanodon\u0163i din Insula Wight. Acest lucru demonstreaz\u0103 c\u00e2t de valoroase sunt aceste colec\u0163ii pentru reevalu\u0103ri pe baza unor date \u015fi perspective noi\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"
