Abstract
The hexactinellid sponges Teganium and Teganiella are widespread in Ordovi-cian, Devonian and Carboniferous strata in Laurentia, but have not previously been reported outside that palaeocontinent; some other members of the family Teganiidae are also restricted to Laurentia. The genus Teganiella in particular is considered to be a Laurentian endemic, with all species specialised for equatorial, shallow-water conditions. However, it is now clear that the diagnostic separation of Teganiella from Tega-nium was based on misunderstanding of the latter
