Arctoceratidae

No picture of Arctoceratidae 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 Arctoceratidae, or no answer at all. This entry cannot say which.

Time the record covers

At least 3.8 million years on record.

The record covers at least 250.8 Mya to 247 Mya. No occurrence read is dated outside 251.1 Mya to 244.4 Mya.

443 occurrences of Arctoceratidae 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

443 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.

450 taxa

The Paleobiology Database records 297 sites for Arctoceratidae, 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.

59 references

Each of the 443 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. 47 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.
