Hypolagus

Hypolagus is an extinct genus of lagomorph, first recorded in the Hemingfordian of North America. It entered Asia during the early Turolian and spread to Europe not much later, where it survived until the Middle Pleistocene. Though unknown in the Iberian Peninsula, fossils of this genus have been found in the Balearic Islands, suggesting an eastern migration during the dry period in the Mediterranean region known as the Messinian Salinity Crisis.

Time the record covers

At least 15 million years on record.

The record covers at least 16.3 Mya to 774 ka. No occurrence read is dated outside 23.04 Mya to 11.7 ka.

289 occurrences of Hypolagus on record, most of them in the Miocene. 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

289 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.

113 references

Each of the 289 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. 101 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.
