methodology, to assess its merit. The term Yinpterochiroptera is constructed from the words Pteropodidae (the family of megabats) and Yinochiroptera (a term proposed in 1984 by Karl F. Koopman to refer to certain families of microbats). Recent studies using transcriptome data have found strong support for the Yinpterochiroptera-Yangochiroptera classification system. Researchers have created a relaxed molecular clock that estimates the divergence between Yinpterochiroptera and Yangochiroptera around 63 million years ago. The most recent common ancestor of Yinpterochiroptera, corresponding to the split between Rhinolophoidea and Pteropodidae (Old World Fruit bats), is estimated to have occurred 60 million years ago. The first appearance of the term Yinpterochiroptera was in 2001, in an article by Mark Springer and colleagues. As an alternative to the subordinal names Yinpterochiroptera and

Yangochiroptera Yangochiroptera, or Vespertilioniformes, is a suborder of Chiroptera that includes most of the microbat families, except the Rhinopomatidae, Rhinolophidae, Hipposideridae, and Megadermatidae. These other families, plus the megabats, are seen ...
