Amphiperatherium

Searched as Amphiperatherium frequens frequens. The Paleobiology Database treats Amphiperatherium as the accepted name.

Amphiperatherium is an extinct genus of metatherian mammal, closely related to marsupials. It ranged from the Early Eocene to the Middle Miocene in Europe. It is the most recent metatherian known from the continent.

Time the record covers

At most 2.4 million years on record.

The one occurrence read is dated to somewhere between 22.4 Mya and 20 Mya, which is a dating window rather than a span.

1 occurrence of Amphiperatherium 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

1 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 68 sites for Amphiperatherium, 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.
