Pogonodon

Pogonodon is an extinct genus of cat-like nimravid endemic to North America during the Oligocene from 32.0 to 25.9 Ma. Including supplementary materials The genus the consists of two species P. davisi and P. platycopis. Pogonodon was the last nimravine to go extinct in North America, possibly due to competition with amphicyonids and expansion of grasslands. Its extinction marked the beginning of the cat gap, a 7 million year period without any cat-like predators in North America.

6 occurrences of Pogonodon on record, most of them in the Oligocene. 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

6 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.

The Paleobiology Database records 6 sites for Pogonodon, 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.

Entered from

6 references

Each of the 6 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. 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.
