Research alert! New insights into mammalian tooth, jaw, and ear evolution, gleaned from analyzing fossils of two Jurassic-era mammal species from China, are reshaping how scientists think about early mammals. This research, led by scientists at the Museum and the Chinese Academy of Sciences, focuses on two new species of fossil mammals—Feredocodon chowi and Dianoconodon youngi—that offer new evidence about early mammalian evolution.
“Scientists have been trying to understand how the mammalian middle ear evolved since Darwin’s time,” said Jin Meng, a curator in the Museum’s Division of Paleontology and a corresponding author on both papers. “These new fossils bring to light a critical missing link and enrich our understanding of the gradual evolution of the mammalian middle ear.”
