Dendroctonus
Dendroctonus is a genus of bark beetles. It includes several species notorious for destroying trees in the forests of North America; the genus name in New Latin is derived from Ancient Greek δένδρον dendron "tree", and κτόνος ktonos "murder", alluding to its ability to kill trees.

Time the record covers
At least 39 million years on record.
The record covers at least 39.7 Mya to 129 ka. No occurrence read is dated outside 45.9 Mya to 11.7 ka.
4 occurrences of Dendroctonus 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
4 occurrences- Eocene25%
- Pleistocene75%
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 4 sites for Dendroctonus, 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.
