Ophiceras
Searched as Ophiceras greenlandicum subplatyspira. The Paleobiology Database treats Ophiceras as the accepted name.
Ophiceras is an extinct genus of smooth, evolute ceratitid ammonites from the Griesbachian, with a rounded venter. Fossils of the genus have been found in Armenia, Azerbaijan, China, Greenland, and India.

Time the record covers
At most 802 thousand years on record.
The one occurrence read is dated to somewhere between 251.902 Mya and 251.1 Mya, which is a dating window rather than a span.
1 occurrence of Ophiceras on record, most of them in the Early Triassic. 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 occurrences- Early Triassic100%
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 268 sites for Ophiceras, 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.
