Time the record covers

At least 17 million years on record.

The record covers at least 66 Mya to 48.07 Mya. No occurrence read is dated outside 72.2 Mya to 37.71 Mya.

920 occurrences of Arctocyonidae on record, most of them in the Paleocene. 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

920 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.

910 taxa

The Paleobiology Database records 505 sites for Arctocyonidae, 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.

124 references

Each of the 920 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. 112 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.

No 3D scan of Arctocyonidae was found in MorphoSource and Sketchfab.

Smithsonian Open Access was not reached for this taxon, so this list is what the others held rather than everything there is.

This is what the site found, which is not the same as what exists.
