MAOTUNIA FROM NORTHERN CHINA

This lovely is Maotunia sp. from the Drumian Changhia Formation of China. You can see the 3D phosphatized gut glands still stuck to the underside of the dorsal carapace. 

Wang et al. published a paper in December 2018 on the fossilized gut of the trilobite Lioparia bassleri and the distribution of exceptional preservation in the Cambrian Stage 4-Drumian Manto Formation of northern China.
