Rhipidomella
Rhipidomella is an extinct genus of brachiopod belonging to the order Orthida and family Rhipidomellidae. Specimens have been found in Carboniferous to Permian beds in southwest Asia, the Moscow Basin, and North America.

Time the record covers
At least 184 million years on record.
The record covers at least 438.6 Mya to 254.14 Mya. No occurrence read is dated outside 443.1 Mya to 251.902 Mya.
1,105 occurrences of Rhipidomella on record, most of them in the Devonian. 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
1,105 occurrences- Silurian9%
- Devonian35%
- Carboniferous32%
- Permian24%
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.
