Hegetotheriidae

Hegetotheriidae is an extinct family of notoungulate mammals known from the Oligocene through the Pliocene of South America. The family underwent many sequential radiation events throughout the Cenozoic, which led to Hegetotheriids being among the most diverse of the Typotheria.

Time the record covers

At least 26 million years on record.

The record covers at least 27.3 Mya to 400 ka. No occurrence read is dated outside 33.9 Mya to 11.7 ka.

292 occurrences of Hegetotheriidae 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

292 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 154 sites for Hegetotheriidae, 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.

107 references

Each of the 292 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. 95 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.
