Trypanoporida

Trypanoporida is an extinct order of encrusting animals from the Tentaculita class, which were common in the Devonian oceans (Weedon, 1991). Their affinity is unknown; they have been placed among worms and corals. They appear to be closely related to other taxa of uncertain affinity, including the microconchids, cornulitids and tentaculitids. Spirally coiled trypanoporids ( Devonian) have most likely been derived from the geologically older microconchids (Upper Ordovician).
