Fossilized galleries of scolytines have been reported in Late Mesozoic wood, but here we describe a well-preserved body fossil from the Cretaceous, c. 100 Ma, preserved in amber from northern Myanmar. Moreover, the specimen is remarkably similar to Recent species of the genus Microborus, revealing stasis unexpected within scolytines and thus highlighting the antiquity of the group. Stratigraphic dating and comparison of insect palaeofaunas included in other well-dated ambers from multiple sites support the age estimate of the Burmese amber. A minimum age for one clade of scolytines is thus established, indicating an early divergence of scolytines from other weevils in the Late Jurassic or Early Cretaceous and challenging the current perspective of weevil evolution.10aScolytinae1 aCognato, Anthony, I.1 aGrimaldi, David  uhttps://weevil.myspecies.info/100-million-years-morphological-conservation-bark-beetles-coleoptera-curculionidae-scolytinae
