Time the record covers
At least 42 million years on record.
The record covers at least 168.2 Mya to 125.77 Mya. No occurrence read is dated outside 170.9 Mya to 121.4 Mya.
113 occurrences of Oxycerites 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
113 occurrences- Middle Jurassic94%
- Late Jurassic5%
- Early Cretaceousunder 1%
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 90 sites for Oxycerites, 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.
