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]
