Time the record covers

At least 18 million years on record.

The record covers at least 157.9 Mya to 139.1 Mya. No occurrence read is dated outside 161.5 Mya to 137.05 Mya.

814 occurrences of Ataxioceratidae on record, most of them in the Late 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

814 occurrences

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.

85 references

Each of the 814 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. 73 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. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
