Crotaphytus collaris
The common collared lizard, also commonly called eastern collared lizard, Oklahoma collared lizard, mountain boomer, yellow-headed collared lizard, and collared lizard, is a North American species of lizard in the family Crotaphytidae. The common name "collared lizard" comes from the lizard's distinct coloration, which includes bands of black around the neck and shoulders that look like a collar. Males can be very colorful, with blue-green bodies, yellow stripes on the tail and back, and yellow-orange throats. Five subspecies are recognized.

Time the record covers
At least 81 thousand years on record.
The record covers at least 210 ka to 129 ka. No occurrence read is dated outside 1.4 Mya to 0 Mya.
10 occurrences of Crotaphytus collaris on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
10 occurrences- Pleistocene99%
- Holoceneunder 1%
These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 10 sites for Crotaphytus collaris, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Each of the 10 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
