For today’s fossil, we have a beautiful specimen of Kellibrooksia macrogaster, which was a species of mantis shrimp (see Mazon Monday #105). This rare animal was described by Frederick Schram in 1973. It was named in honor of Harold Kelly Brooks, who published the first well-illustrated modern account of Mazon Creek crustaceans.  A pdf of his work is available. Have a look as it has some amazing illustrations!

This contribution comes from Alan Keith. Alan is a very serious Mazon Creek collector. He travels up here from Texas multiple times each year to collect concretions he can process back home. Thanks for sharing, Alan!
