Camptostroma roddyi is an extinct echinoderm from the Bonnia-Olenellus Zone of the Early Cambrian Kinzers Formation near York and Lancaster, Southeastern Pennsylvania.

"[3] In life, Camptostroma would have resembled a cupcake, with the mouth in the center of the upper surface, with ambulacra radiating from it in the 2-1-2 pattern common in early echinoderms.

[5] While initially considered to be a scyphozoan due to the fossil's medusoid shape, later investigation detected the presence of stereom plates with the calcitic cleavage pattern diagnostic of echinoderms.

[7] Camptostroma has since been placed in a class of basal echinoderms, the Edrioasteroids,[8] although some recent authors only describe it as "edrioasteroid-like".

[5] Recent research has found weak support for the recovery of Camptostroma as the sister group of the crinoids.
