Pollinating insects played a decisive role in the origin and early evolution of the angiosperms. Pollinating orthorrhaphous Brachycera fossils (short-horned flies) collected from Late Jurassic rocks in Liaoning Province of northeast China provide evidence for a pre-Cretaceous origin of angiosperms. Functional morphology and comparison with modern confamilial taxa show that the orthorrhaphous Brachycera were some of the most ancient pollinators. These data thus imply that angiosperms originated during the Late Jurassic and were represented by at least two floral types.
传粉昆虫在被子植物的起源和早期演化过程中发挥了决定性作用。在中国东北辽宁省晚侏罗世岩石中采集到的直裂短角亚目（短角蝇）传粉化石为被子植物的白垩纪前起源提供了证据。功能形态学以及与现代同科类群的比较表明，直裂短角亚目是一些最古老的传粉者。这些数据因此意味着被子植物起源于晚侏罗世，并且至少由两种花的类型代表。
