Genus: Rhiodenticulatus BERMAN & REISZ, 1986
Etymology: Greek, rhinos, “nose, snout” and Latin, denticulatus, “with small teeth”: Small-toothed snout.

Species: heatoni BERMAN & REISZ, 1986
Etymology:

Holotype: UCMP 35757

Locality: Rio Puerco drainage, Rio Arriba County, North-central New Mexico.

Horizon: Upper Cutler Formation.

Biostratigraphy:

Age: Wolfcampian Stage, Lower Rotliegendes Epoch, Early Permian.

Material: Skull, lower jaw, vertebral series with ribs from the axis to the 7th caudal, pectoral and pelvic girdles, right humerus, proximal ends of ulna and radius, femora, left tibia, fibulae and tarsi; skull
not attached to postcranial skeleton.

Referred material:

UCMP 40209: Skull with closely joined lower jaw, missing left postorbital cheek region and posterior half of left mandible.

UCMP 40210: Partial articulated postcanial skeleton preserved in 3 small segments. 1) a series of 7 postaxial cervical and dorsal vertebrae with ribs, essentially complete pectoral girdle, and proximal ends of humeri; 2) series of 6 vertebrae that includes the last 2 presacrals, 2 sacrals with ribs, and the first 2 caudals, and pelvis, and 3) portion of the left hindlimb, including proximal 2 thirds of femur and nearly complete tibia. It is quite likely that UCMP 40209 and UCMP 40210 belong to the same individual.
