Back in Mazon Monday #65, we highlighted Paleocaris typus. Today, we have a specimen from Pit 11.  This fossil was found in March 2021 and opened via freeze/thaw in May 2021.  It was collected by ESCONI member Rich Holm.  If you look close, you’ll see the diagnostic telson, which indicates this to be a Paleocaris typus.  The following drawing is by Don Auler and comes from “ESCONI Keys to Mazon Creek Animals”.
