This may be one of the largest best preserved brachiopods I have ever found, measuring over 5 cm in width. It was recovered from the Silver Creek Limestone of Clark County, Indiana and appears to be a Protoleptostrophia perplana?. Originally, I thought this was a Megastrophia in an earlier posting (CLICK HERE) but Dave at Views of the Mahantango blog pointed out that error.
Thanks to Kenny for cleaning the matrix off this specimen with sand abrasive cleaning. See further down in this posting for before and after pictures of both sides. It really is clean!
