Tymbochoos is an extinct genus of encrusting tentaculitoid tubeworms. Tymbochoos has a laminar tube structure and pseudopuncta similar to those of the tentaculitoids.^[2] It has previously been interpreted as a Palaeozoic polychaete.^[1] The world's oldest build-ups with tube-supported frameworks belong to Tymbochoos sinclairi.^[3] They occur in the Ordovician limestones of the Ottawa Valley.^[1]
