Due to the fragmentary nature of Texasetes, little is known directly from the fossils and the uncertain phylogenetic position limits inferable traits. The preserved teeth are unique in that they have a large ridge leading up to the apex of the tooth's crown, with this feature known in only one other taxon from southern England.
Because Texasetes is fragmented, we know little about it directly from fossils.  The uncertain position of its place on the evolutionary tree limits what traits can be inferred. However, the teeth are unique because they have a large ridge leading up to the tooth's crown apex, and this feature is only found in one other taxon from southern England.
