Source-derived summary

The Baja California collared lizard or Baja black-collared lizard (Crotaphytus vestigium) is a species of lizard in the family Crotaphytidae. The species is endemic to southern California (United States) and Baja California (Mexico).

Description

The Baja California collared lizard is a large-bodied species of lizard with a broad head, short snout, granular scales, and two distinct black collar markings. The collar markings are separated at the dorsal midline by more than 12 pale scales. It is tan to olive-colored with broad dark crossbands on its body. Adults are between 6.9 and 11.2 cm (2.7 and 4.4 in) long (snout–vent length). Young lizards look similar to adults, but with more distinct banding. The males of this species have enlarged postanal scales, a blue-grey throat, and large dark blotches on their flanks.

Behavior

C. vestigium is a powerful bipedal runner. Adults can inflict a painful bite.

Editorial summary

The public source identifies “Baja California collared lizard” as species of reptile. This brief keeps that definition visible, then builds a research path around Baja, California and collared.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 144-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Baja, California and collared providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Baja California collared lizard”, the useful work is to connect “species of reptile” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 25, 2026.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
