Vegaviidae
Vegaviidae is a proposed extinct family of neognathous, possibly anseriform birds which lived during the Late Cretaceous and possibly the Paleocene. The monophyly of the family has been questioned by subsequent studies, with the only definitive member Vegavis known from the Maastrichtian stage of Antarctica, though some fossil genera from other continents have been assigned to this clade.

Time the record covers
At least 24 million years on record.
The record covers at least 72.2 Mya to 48.07 Mya. No occurrence read is dated outside 83.6 Mya to 33.9 Mya.
9 occurrences of Vegaviidae on record, most of them in the Late Cretaceous. 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
9 occurrences- Late Cretaceous60%
- Paleocene29%
- Eocene11%
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 9 sites for Vegaviidae, 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.

Each of the 9 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.
