Odonata
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies. The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies are usually more slender with eyes placed apart and wings folded together along body at rest. Adult odonates can land and perch, but rarely walk.

Time the record covers
At least 309 million years on record.
The record covers at least 309.8 Mya to 11.7 ka. No occurrence read is dated outside 314.6 Mya to 0 Mya.
1,679 occurrences of Odonata on record, most of them in the Early Cretaceous. 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.

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 713 sites for Odonata, and this reads 240 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 1,679 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. 543 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.
