Tommotiids are an extinct group of Cambrian invertebrates thought to be early total-group lophophorates (the group containing Bryozoa, Brachiopoda, and Phoronida), including members of the lophophorate stem group, as well as early diverging members of the crown group.
The majority of tommotiids are mineralised with calcium phosphate rather than calcium carbonate, although silicified examples hint that some species bore carbonate or carbonaceous sclerites.
