of mammals. In 2016, family S24-7 was studied in-depth and given the name "''Homeothermaceae''", however, as no isolates were provided as type material, the name was not validated. The first isolated member of this family was '' Muribaculum intestinale'' as part of the mouse intestinal bacterial collection (miBC) in 2016. However, validation of the family only occurred in 2019 after detailed analysis of this family, along with description of ''Duncaniella'' and ''Paramuribaculum'', two additional genera within this family. In a recent study on mice, members of the family ''Muribaculaceae'' were shown to be major utilisers of
