Diadophis punctatus
Diadophis punctatus, commonly known as the ring-necked snake or ringneck snake, is a small, harmless species of colubrid snake found throughout much of the United States, as well as south in Central Mexico and as far north as Nova Scotia, Canada. Ring-necked snakes are generally fossorial and somewhat secretive, by nature, and, as a nocturnal species, are rarely seen during the daytime. These snakes are believed to be fairly abundant throughout most of their range, though no scientific evaluation supports this hypothesis. Scientific research is lacking for the species, despite their apparently common status, and more in-depth investigations are greatly needed. It is the only species within the genus Diadophis and, currently, 14 subspecies are identified, though many herpetologists question the morphologically based classifications.

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 11.7 ka.
7 occurrences of Diadophis punctatus on record, most of them in the Pleistocene. 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
7 occurrences- Pleistocene100%
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 7 sites for Diadophis punctatus, 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.
