Time the record covers
At least 238 million years on record.
The record covers at least 422.7 Mya to 184.2 Mya. No occurrence read is dated outside 426.7 Mya to 161.5 Mya.
387 occurrences of Spiriferina on record, most of them in the Early Jurassic. 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

- Early Jurassic40%
- Middle Jurassicunder 1%
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.
