Gulf Coast horned lizard Gulf Coast horned lizard The Gulf Coast horned lizard ("Phrynosoma wigginsi" ) is a species of horned lizards native to Baja California, Mexico. "Phrynosoma wigginsi" was split from "Phrynosoma coronatum" in 2004 on morphological evidence. "P. wigginsi" has a tan rather than chocolate forehead, a fourth "subrictal" spine below the eye, and a longer head than "P. coronatum". The specific name, "wigginsi", is in honor of Stanford University botanist Ira Loren Wiggins, who in 1946 collected what later became the holotype. The geographic range of "P. wigginsi" is restricted to the region around Mulegé and Loreto on the Gulf Coast
