#Icaronycteris is an extinct genus of microchiropteran (echolocating) bat that lived in the early #Eocene, approximately 52.2 million years ago, making it the earliest bat genus known from complete skeletons, and the earliest known bat from North America
I am a bit annoyed that they didn't cite our paper on the Eocene carbon transfer by mass flows. I'm fairly sure at least one of the authors was aware of it.
