The Soricomorpha ("shrew-form") was a proposed biological group in the class of mammals. It includes all the shrews, solenodons and moles. It is divided into 4 families, one extinct. The other three families are the shrews, solenodons and moles. This followed the discovery, from sequence analysis, that the old order Insectivora was polyphyletic. That meant it was not a single clade.
