Sceloporus
Spiny lizards is a common name for the genus Sceloporus in the family Phrynosomatidae. The genus is endemic to North America, with various species ranging from New York, to Washington, and one occurring as far south as northern Panama. The greatest diversity is found in Mexico. This genus includes some of the most commonly seen lizards in the United States. Other common names for lizards in this genus include fence lizards, scaly lizards, bunchgrass lizards, and swifts.

Time the record covers
At least 16 million years on record.
The record covers at least 16.3 Mya to 129 ka. No occurrence read is dated outside 18.5 Mya to 0 Mya.
56 occurrences of Sceloporus 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
56 occurrences- Miocene21%
- Pliocene9%
- Pleistocene70%
- 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 49 sites for Sceloporus, 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 56 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. 28 further references are not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
