Janograptus
No picture of Janograptus was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Janograptus, or no answer at all. This entry cannot say which.

Time the record covers
At least 6.9 million years on record.
The record covers at least 468 Mya to 461.1 Mya. No occurrence read is dated outside 477.1 Mya to 458.2 Mya.
4 occurrences of Janograptus on record, most of them in the Ordovician. 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
4 occurrences- Ordovician100%
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 4 sites for Janograptus, and this reads all 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.
Entered from
4 references- Unpublished notes on Norwegian Ordovician fossil occurrences compiled from various resources, primarily from the series of papers on taxa of the Middle Ordovician on the Oslo-Asker District, published in Norsk Geologisk Tidsskrift1
- Summary of regional geology of Hu''nan Province, China1
- Stratigraphic table of northwestern region of China: XinJiang Province part1
- The Middle Ordovician of the Oslo region, Norway, 16. Graptolites of the Ogygiocaris Series1
Each of the 4 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. Each entry links to the Paleobiology Database's own record for the work.
