113 miljoner \u00e5r gammalt myrfossil ger insikter i evolutionen<\/h2>\n

Brasilianska forskare har hittat v\u00e4rldens \u00e4ldsta k\u00e4nda myrfossil, som ber\u00e4knas vara 113 miljoner \u00e5r gammal<\/strong>. Detta extraordin\u00e4ra fynd kastar nytt ljus \u00f6ver myrornas evolution och avsl\u00f6jar en art fr\u00e5n en utd\u00f6d grupp som kallas \"helvetesmyror\", n\u00e4ra besl\u00e4ktad med de moderna myrornas getingliknande f\u00f6rf\u00e4der. Fossilet finns bevarat i kalksten fr\u00e5n Brasiliens Crato-formation och \u00f6kar avsev\u00e4rt v\u00e5r f\u00f6rst\u00e5else f\u00f6r myrornas historia.<\/p>\n

Mikrodatortomografi avsl\u00f6jar fantastiska anatomiska s\u00e4rdrag<\/h2>\n

Anv\u00e4nda mikrodatortomografi<\/strong>Efter att ha studerat fossilen skapade forskarna en detaljerad 3D-bild av den och avsl\u00f6jade dolda anatomiska drag. Ett utm\u00e4rkande drag \u00e4r myrans lie-liknande k\u00e4kar, som spetsade bytet - till skillnad fr\u00e5n moderna myror, som anv\u00e4nder sidogreppande k\u00e4kar f\u00f6r att f\u00e5nga sin f\u00f6da.<\/p>\n<\/section>\n

Forntida rovdjur som levde sida vid sida med dinosaurier<\/h2>\n

Detta fossil ing\u00e5r i den utd\u00f6da underfamiljen Haidomyrmecinae<\/strong>, som trivdes under kritaperioden och levde sida vid sida med dinosaurier. Namnet Vulcanidris cratensis<\/strong>uppt\u00e4ckten f\u00f6reg\u00e5r tidigare fossil av helvetesmyror som hittats i b\u00e4rnsten fr\u00e5n Myanmar och Frankrike, vilket st\u00e4rker artens utbredda n\u00e4rvaro \u00f6ver kontinenterna.<\/p>\n<\/section>\n

En uppt\u00e4ckt som f\u00f6r\u00e4ndrar allt om f\u00f6rhistoriska insekters evolution<\/h2>\n

F\u00f6rutom att bidra till den vetenskapliga kunskapen belyser fossilen livets m\u00e5ngfald under f\u00f6rhistorisk tid. Insekter som helvetesmyror spelade anm\u00e4rkningsv\u00e4rda roller tillsammans med dinosaurier och uppvisade specialiserade beteenden och unika anatomier. Forskarna hoppas att framtida uppt\u00e4ckter ytterligare kommer att knyta ihop myrornas evolution\u00e4ra pussel.<\/p>\n<\/section>\n
