Aciculopoda is an extinct prawn which existed in what is now Oklahoma approximately 360 million years ago. It was described in 2010 on the basis of a single fossil from Oklahoma. The single species Aciculopoda mapesi was named by Rodney Feldmann and Carrie Schweitzer in honour of Royal Mapes a paleontologist who discovered the type specimen. It is only the third unambiguous fossil decapod from before the Mesozoic.
