| Summary: | Three specimens corresponding to a new echinoid species from the Upper Creta - ceous (Lower Campanian) from Austin Formation in the northeastern of Mex - ico are reported here. The morphology of the specimens (test with a cordiform aboral region) as well as the sedimenta - ry environment reported at the Austin Formation, suggests that this species represents an infaunal and detritivorous dweller living in a shallow water environ - ment within the continental shelf. This is consistent with the more actual knowledge for other species of Diplodetus. |
