Castor fiber
The Eurasian beaver or European beaver is a species of beaver widespread across Eurasia, with a rapidly increasing population of at least 1.5 million in 2020. The Eurasian beaver was hunted to near-extinction for both its fur and castoreum, with only about 1,200 beavers in eight relict populations from France to Mongolia in the early 20th century. It has since been reintroduced into much of its former range and now lives from Western, Southern, Central and Eastern Europe, Scandinavia, Russia through China and Mongolia, with about half the population in Russia. It is listed as least concern on the IUCN Red List.

Time the record covers
At least 7.2 million years on record.
The record covers at least 7.246 Mya to 11.7 ka. No occurrence read is dated outside 66 Mya to 0 Mya.
66 occurrences of Castor fiber on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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
66 occurrencesThese 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 66 sites for Castor fiber, 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.

Each of the 66 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. 26 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.
