Rosoideae Focke亚科（蔷薇科）在北半球有很好的化石记录，但这些化石记录主要局限于少数属，而大多数属，特别是那些有草本成员的属，仍然缺乏代表性。本研究描述了云南西北部上新世晚期玫瑰总科的新果实化石，包括fragariaachenes和rubusendocarps。这些化石为玫瑰总科的化石档案增添了新的内容，并提供了东亚地区的第一个玫瑰总科化石记录。新的化石发现为该亚科在云南西北部的现代多样性和分布提供了历史背景，这是一个地形复杂的地区，可容纳许多植物类群的高度多样性。我们的鲁布斯化石，结合附近其他同时期出现的鲁布斯属，表明在上新世晚期，鲁布斯已经在云南西北部建立了它的现代多样性。
The subfamily Rosoideae Focke (Rosaceae) has a good fossil record in the Northern Hemisphere, but these fossil records are confined mainly to a few genera, whereas the majority, in particular those with herbaceous members, are still under‐represented. In this study, we describe new fruit fossils of Rosoideae, includingFragariaachenes andRubusendocarps, from the late Pliocene of northwestern Yunnan, Southwest China. These fossils add new accounts to the fossil archive of Rosoideae and provide the first fossil record ofFragariain East Asia. The new fossil findings provide a historical backdrop for the modern diversity and distribution of the subfamily in northwestern Yunnan, a topographically complex area accommodating a high diversity for many plant groups. OurRubusfossils, in combination with other nearby coeval occurrences of the genus, suggest thatRubuswas already establishing its modern diversity in northwestern Yunnan during the late Pliocene. This finding enriches our knowledge of the post‐Neogene diversification of flowering plants in northwestern Yunnan, which is thought to be largely driven by dramatic mountain uplifts and environmental complications associated with the southeastern extension of the Tibetan Plateau.
