Dichobunidae

Dichobunidae is an extinct family of basal artiodactyl mammals from the early Eocene to late Oligocene of North America, Europe, and Asia. The Dichobunidae include some of the earliest known artiodactyls, such as Diacodexis.

Time the record covers

At least 23 million years on record.

The record covers at least 51.1 Mya to 27.3 Mya. No occurrence read is dated outside 56 Mya to 23.04 Mya.

158 occurrences of Dichobunidae on record, most of them in the Eocene. 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

158 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.

1,330 taxa

The Paleobiology Database records 80 sites for Dichobunidae, 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.

59 references

Each of the 158 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.
