Australidelphia

Australidelphia is a superorder of marsupials encompassing about three-quarters of all living marsupial species, including all those native to Australasia and one South American species, the monito del monte. Australidelphia's lineage emerged in South America, with genetic evidence indicating that the South American monito del monte is sister to all other members of the superorder, unlike other American marsupials, which belong to the Ameridelphia.

Time the record covers

At least 61 million years on record.

The record covers at least 61.66 Mya to 11.7 ka. No occurrence read is dated outside 66 Mya to 0 Mya.

2,043 occurrences of Australidelphia on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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

2,043 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.

883 taxa

The Paleobiology Database records at least 502 sites for Australidelphia, 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.

Entered from

258 references

Each of the 2,043 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. 246 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.
