Devonian Fish Provides Unique Insights into the Early Evolution of Modern Lobe-finned Fishes
In a study published June 3 in the journal of Science Advances, Drs. LU Jing and ZHU Min, Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences, and their collaborators described newly discovered skull material of Qingmenodus, an onychodont from South China about 409 million years ago, using high-resolution computed tomography to image internal structures of the braincase. This study provides the first detailed interpretation of internal neurocranial anatomy in onychodonts, and helps us to understand the sequence of character acquisition in the early evolution of sarcopterygians, illuminating the early evolution and diversification of modern sarcopterygians.
