Mucrospirifer mucronatus
Mucrospirifer mucronatus is a species of articulate brachiopod from the middle Devonian. The species serves as an index fossil for the middle Devonian.

Time the record covers
At most 22 million years on record.
Every occurrence read is dated to somewhere between 393.47 Mya and 372.15 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
466 occurrences of Mucrospirifer mucronatus 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
466 occurrences- Devonian100%
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 370 sites for Mucrospirifer mucronatus, 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.

Each of the 466 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. 19 further references are not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
