Early Cambrian Trilobite - Yinites?

[connorp]

I purchased this trilobite fossil a while back. It was sold as Yinites sp. from the Early Cambrian Hongjingshao formation in China. I tried to both verify the genus and close in a species, but have been unable to do so. All the references to Yinites that I could find were old (circa 1940’s), and therefore I wasn’t able to find any actual literature online. Does anyone have any ideas?

Papers from the 6th International Conference on Trilobites and their Relatives might be useful, but it’s expensive. Wish I had a copy that I could check for you, but they cover the Hongjingshao species at some length.

Thanks @piranha. I just looked and my university library has a copy of the Kaesler text, I'll be picking it up tomorrow to take a look.
