Plagiodontia araeum

Hyperplagiodontia, rarely called the wide-toothed hutia, is an extinct genus of hutia which contains a single species, Hyperplagiodontia araeum. The species was originally described as a member of the genus Plagiodontia along with the extant Hispaniolan hutia, but after morphometric analysis in 2012, was moved to its own genus, Hyperplagiodontia. Fossils of H. araeum have only been found on Hispaniola, in the Dominican Republic and Haiti.

Time the record covers

At most 129 thousand years on record.

Every occurrence read is dated to somewhere between 129 ka and 0 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

3 occurrences of Plagiodontia araeum 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

3 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.

15 taxa

The Paleobiology Database records 3 sites for Plagiodontia araeum, and this reads all of them. The number is how many of those sites it was catalogued from too.

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

1 reference

Each of the 3 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. Each entry links to the Paleobiology Database's own record for the work.
