Nipponitrigonia
Searched as Nipponitrigonia sagawai sagawai. The Paleobiology Database treats Nipponitrigonia as the accepted name.
No picture of Nipponitrigonia was found. Wikidata and iDigBio were searched and had none. Wikipedia and 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 Nipponitrigonia, or no answer at all. This entry cannot say which.

Time the record covers
At least 13 million years on record.
The record covers at least 168.2 Mya to 154.8 Mya. No occurrence read is dated outside 170.9 Mya to 143.1 Mya.
4 occurrences of Nipponitrigonia on record, most of them in the Middle 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
4 occurrencesThese 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 30 sites for Nipponitrigonia, 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
1 referenceEach 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.
