Typotheria
Typotheria is a suborder of the extinct South American native ungulate order Notoungulata. A majority of the members of this clade were superficially similar to lagomorphs and rodents, though this is due to convergence. The clade was named after Typotherium, a synonym of Mesotherium.

Time the record covers
At least 55 million years on record.
The record covers at least 56 Mya to 129 ka. No occurrence read is dated outside 57 Mya to 11.7 ka.
823 occurrences of Typotheria 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
823 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 315 sites for Typotheria, 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 823 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. 189 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.
