The occurrence of one specimen of Paraconularia sp. with the apex connected to a crinoid cirrus is described and figured for the first time. This disposition suggests that the conulariid had a primary, apical attachment to the crinoid. The material comes from Puesto La Carlota (Chubut Province, Argentina) and belongs to the Callitomaria tepuelensis-Streblochondria sp. Zone (Early Permian).
