Fenestella
Fenestella is a genus of bryozoans or moss animals, forming fan–shaped colonies with a netted appearance. It is known from the Middle Ordovician to the early Upper Triassic (Carnian), reaching its largest diversity during the Carboniferous. Many hundreds of species have been described from marine sediments all over the world.

Time the record covers
At least 196 million years on record.
The record covers at least 450.2 Mya to 254.14 Mya. No occurrence read is dated outside 454 Mya to 251.902 Mya.
983 occurrences of Fenestella on record, most of them in the Carboniferous. 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
983 occurrences- Ordovician2%
- Silurian8%
- Devonian23%
- Carboniferous39%
- Permian29%
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 775 sites for Fenestella, and this reads 240 of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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.
