白垩纪陆地革命

白垩纪陆地革命[1]英语Cretaceous Terrestrial Revolution,简称KTR)也称被子植物陆地革命Angiosperm Terrestrial Revolution,简称ATR),是指白垩纪中晚期(1.25亿至8000万年前)因被子植物的兴盛而相应引发的传粉昆虫与之共同演化、以及有食虫/食/食习性的鸟类哺乳动物有鳞爬行类滑体两栖类结网蜘蛛等随即出现的快速演化辐射事件[2]

这一概念出现之前,古生物学界已广泛接受,恐龙的许多新产生于白垩纪中到晚期,包括 鸭嘴龙科角龙亚目甲龙科厚头龙亚目鲨齿龙科伤齿龙科驰龙科以及似鸟龙类。然而,Lloyd等人2008年发表的一篇新论文指出,此期间恐龙显著的“新的多样化”,系由于化石记录的取样偏误,以及白垩纪时代的沉积物比更早的三叠纪侏罗纪的沉积物保存得更好。[2]遗传学证据表明,在KTR期间,竹节虫目昆虫经历了大规模辐射演化,这可能是为了应对同时期的反鸟类等视觉性捕食者的辐射演化。[3]
