This is a very nice Encrinurid trilobite. It is Encrinuroides enshiensis from the Lower Silurian of China. This distinct trilobite is nicely inflated and displays well on the chunk of matrix. The trilobite has fine detail and is covered with large pustules. The bug has striking, dark color that contrasts wonderfully with the light-colored matrix. This is a very good example of Encrinuroides enshiensis from China.
