WE are interested on the origin and evolution of invertebrate animals as informed by exceptionally preserved fossils from Paleozoic deposits. Our research brings together specimen-based traditional paleontology and fieldwork, developmental biology of extant organisms, and state of the art imaging and analytical techniques to study the evolutionary history of euarthropods and their close relatives.

Cambrian ancestor of crustaceans in 3D

December 27, 2018

In our latest study, we describe the three dimensionally preserved appendage morphology of the bivalved euarthropod Ercaicunia multinodosa from the early Cambrian Chengjiang biota of South China, made possible through collaboration with colleagues Dayou Zhai and Yu Liu from Yunnan University in Kunming. Our findings of differentiated head appendages, including tritocerebral antennae and mandibles, as well as delicate details of the trunk limbs such as the epipodite, allow us to conclude that Ercaicunia belongs to the stem-group of Pancrustacea (i.e. crustaceans and...
