Pygmy Short-horned Lizard vs. Blainville's Horned Lizard

Both are flat, round horned lizards; their records touch in northern California (blurred records). A: Tiny stubs, shorter than the eye is wide in the Pygmy Short-horned Lizard; long, sharp horns at the back of the head in the Blainville's Horned Lizard. B: One row of small fringe scales in the Pygmy Short-horned Lizard; two rows of pointed fringe scales in the Blainville's Horned Lizard. Range decides most of the time: sagebrush and pine of the far northeast (Pygmy) vs the Coast Ranges, Sierra foothills and the south (Blainville's).
