Pilosa
Pilosa is an order of xenarthran placental mammals, native to the Americas. They include anteaters and sloths. The name comes from the Latin word for "hairy".

Time the record covers
At least 37 million years on record.
The record covers at least 37.71 Mya to 11.7 ka. No occurrence read is dated outside 41.03 Mya to 0 Mya.
1,713 occurrences of Pilosa 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
1,713 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 907 sites for Pilosa, 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.

Each of the 1,713 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. 584 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.
