I'm looking at an unknown trilobite from the Chengjang site in China and it has this weird looking thing on the thorax. Is it a fossil, and if so what is it?

I'm looking at purchising a fossil that is labeled anomalocarid. It's not super well preserved, but looks like part of an anomalcarid arm. Is it an anomalocarid or something else.
