Caseoides is an extinct genus of large caseid synapsids that lived in the Kungurian Age (late Early Permian epoch).

Its fossils were found in San Angelo Formation, Texas.

[1] Caseoides was very similar to Casea, but was slightly larger in size.

Caseoides was a heavily built creature, as are most of the Caseids (except Caseopsis).

In the development of its proportionally thick, stout limbs it represents the culmination of the Casea lineage.
