Micrina is an extinct genus of tommotiids with affinities to brachiopods.[1]

Micrina can be considered a stem group brachiopod based on its larval shell.[2]
Its microstructure is very brachiopod like[3] and its adult morphology is similarly bivalved,[4] even though it was once thought to be halkieriid-like.[5]
Micrina is quite similar to Mickwitzia in terms of shell microstructure. The two genera are evidently closely related.
