Lampropeltis triangulum

The milk snake or milksnake, is a species of kingsnake; there were once up to 24 subspecies recognized, however fewer are officially recognized today. Lampropeltis elapsoides, the scarlet kingsnake, was formerly classified as a 25th subspecies, but is now recognized as a distinct species. The previously delineated subspecies have strikingly different appearances, and many of them have their own common names. Morphological and genetic data suggest that this species could be split into several separate species, and it has been by several authorities. Lampropeltis gentilis, Lampropeltis annulata, Lampropeltis abnorma, Lampropeltis polyzona, and Lampropeltis micropholis have been elevated to the species level. Milksnakes are not venomous.

15 occurrences of Lampropeltis triangulum 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

15 occurrences

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 15 sites for Lampropeltis triangulum, 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.

Entered from

13 references

Each of the 15 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. 1 further reference is not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
