Abstract

A supposed giant spider, Mongolarachne chaoyangensis Cheng, Liu, Huang, Liu, Li & Li, 2019, from the Lower Cretaceous Yixian Formation of China, is here shown, with the aid of fluorescence microscopy, to be a faked fossil spider, with a fossil crayfish as its core. We tentatively place M. chaoyangensis in Cricoidoscelosus aethus Taylor, Schram & Shen, 1999 n. syn..
