Abstract

Suprising new fossils - a skeleton and a jaw - give us a much clearer picture of mammals that lived during the time of non-avian dinosaurs; the new finds illuminate the early evolution of the lineage leading to modern mammals, and challenge traditional understanding of placental mammal evolution and biogeography.

摘要

令人惊讶的新化石——一具骨骼和一块颌骨——让我们对生活在非鸟类恐龙时代的哺乳动物有了更清晰的认识；这些新发现阐明了通向现代哺乳动物的谱系的早期进化，并挑战了对胎盘哺乳动物进化和生物地理学的传统理解。
