Allenbya holmesae
Allenbya is an extinct odonate genus possibly in the damselfly-like family Dysagrionidae with the single included species Allenbya holmesae. The genus was first described in 2022 from an Early Eocene Okanagan Highlands site in western North America. The species is known from the late Ypresian sediments exposed around Princeton in Central British Columbia.

Time the record covers
At most 8 million years on record.
The one occurrence read is dated to somewhere between 56 Mya and 48.07 Mya, which is a dating window rather than a span.
1 occurrence of Allenbya holmesae on record, most of them in the Eocene. 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
1 occurrences- Eocene100%
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 1 site for Allenbya holmesae, and this reads all of them. The number is how many of those sites it was catalogued from too.
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.
