化石的发现可以改变我们对植物在时间和空间上多样化的理解。最近描述的化石在许多植物科推他们的已知记录更远的时间，指出替代方案，其起源和spreaded.There，我们描述了两个新的始新世化石浆果的茄科（茄科）的埃斯梅拉达斯形成在哥伦比亚和科罗拉多（美国）的绿色河形成。化石的位置进行了评估，使用聚类和简约分析的基础上10个离散和5个连续的字符，这也得分在291现存taxa.The哥伦比亚化石与tomatillo亚部落的成员分组，和Coloradan化石与辣椒辣椒部落对齐。沿着两个先前报道的早始新世番茄属化石，这些发现表明，早始新世茄科至少分布在南美洲南部到北美洲西北部。连同最近发现的另外两个始新世浆果，这些化石表明，多样化的浆果分支，反过来，整个茄科，比以前想象的要古老得多，而且在过去也更普遍。
Fossil discoveries can transform our understanding of plant diversification over time and space. Recently described fossils in many plant families have pushed their known records farther back in time, pointing to alternative scenarios for their origin and spread.Here, we describe two new Eocene fossil berries of the nightshade family (Solanaceae) from the Esmeraldas Formation in Colombia and the Green River Formation in Colorado (USA). The placement of the fossils was assessed using clustering and parsimony analyses based on 10 discrete and five continuous characters, which were also scored in 291 extant taxa.The Colombian fossil grouped with members of the tomatillo subtribe, and the Coloradan fossil aligned with the chili pepper tribe. Along with two previously reported early Eocene fossils from the tomatillo genus, these findings indicate that Solanaceae were distributed at least from southern South America to northwestern North America by the early Eocene.Together with two other recently discovered Eocene berries, these fossils demonstrate that the diverse berry clade and, in turn, the entire nightshade family, is much older and was much more widespread in the past than previously thought.
