Monograptidae
Monograptidae is an extinct family of graptolites of the order Graptoloidea. Monograptids have only one row of thecae per stipe, unlike the biserial graptolites which have two opposing rows of thecae per stipe.

Time the record covers
At least 49 million years on record.
The record covers at least 459.7 Mya to 410.62 Mya. No occurrence read is dated outside 471.3 Mya to 382.31 Mya.
1,466 occurrences of Monograptidae on record, most of them in the Silurian. 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
1,466 occurrences- Ordovicianunder 1%
- Silurian86%
- Devonian13%
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 475 sites for Monograptidae, 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 1,466 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. 146 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.
