Pterosauria
Pterosaurs are an extinct clade of warm-blooded flying reptiles in the order Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous. Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger.

Time the record covers
At least 155 million years on record.
The record covers at least 227.3 Mya to 72.2 Mya. No occurrence read is dated outside 237 Mya to 66 Mya.
1,162 occurrences of Pterosauria on record, most of them in the Early Cretaceous. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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
1,162 occurrences- Late Triassic4%
- Early Jurassic6%
- Middle Jurassic6%
- Late Jurassic19%
- Early Cretaceous38%
- Late Cretaceous29%
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 828 sites for Pterosauria, 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.
