Fissiletag Posted January 22, 2023 Share Posted January 22, 2023 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? 1 Link to comment Share on other sites More sharing options...
Advantage Posted January 22, 2023 Share Posted January 22, 2023 ? A conularid or Annelid perhaps. I collect from the Albion and Cenomanian so I`m sure others on here have far more idea than me re your specimen. 1 Link to comment Share on other sites More sharing options...
