Marie Angkuw sent us these photos of a gorgeous Laveineopteris rarinervis from the Mazon River. Laveineopteris rarinervis, a seed fern, is pretty commonly found in Mazon Creek localities (see Mazon Monday #81). This specimen was collected from one of the I&M Canal Corridor benefits on the Kodat farm. The concretion opened via the freeze/thaw process this past winter.

Thanks for sharing, Marie!
