Desmodus stocki

Desmodus stocki, or Stock's vampire bat, is an extinct species of vampire bat native to Pleistocene North America, inhabiting states including Arizona, West Virginia, and Florida, further north than any living vampire bats. It weighed about 50% more than the common vampire bat, and was also more robust.

Time the record covers

At most 199 thousand years on record.

Every occurrence read is dated to somewhere between 210 ka and 11.7 ka, and nothing in the dating separates them, so that window is what the record shows rather than a span.

8 occurrences of Desmodus stocki on record, most of them in the Pleistocene. 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

8 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 7 sites for Desmodus stocki, 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

7 references

Each of the 8 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.
