DistributionUSA (E Oregon, S Idaho, Nevada, E Utah, SW California, W Arizona), Mexico (Baja California Norte)

Type locality: Great Salt Lake, Utah.  
Reproductionoviparous 
TypesHolotype: USNM 189 ? (fide SMITH & TAYLOR 1950)
Holotype: USNM 18444, female [calidiarum] 
Diagnosis 
CommentSynonymy partly after SMITH & TAYLOR 1950.

Subspecies: The subspecies of P. platyrhinos are questioned by Pianka (1991). MULCAHY et al. 2006 elevated Phrynosoma platyrhinos goodei to full species status based on mtDNA sequences. MULCAHY et al. 2006 also presented evidence for goodei x mcalli hybrids. KÖHLER 2021 synonymized Phrynosoma platyrhinos calidiarum with the nominate subspecies, and moved goodei (back) to platyrhinos.

Group: Belongs to the Doliosaurus clade fide LEACHE & MCGUIRE 2006.

Distribution: see map in Mulcahy et al. 2006: 1809 (Fig. 3). Not in Sonora fide Lemos-Espinal et al. 2019.

Genome: KOOCHEKIAN et al. 2022.

Diet: a large percentage of the diet of this species (50-80%) consists of ants (Lucas et al. 2023). 
EtymologyThe name platyrhinos is a combination from the Greek "platy” (broad, or flat) and "rhino” (nose).
