Magnoliopsida
Magnoliopsida is a valid botanical name for a class of flowering plants. By definition the class will include the family Magnoliaceae, but its circumscription can otherwise vary, being more inclusive or less inclusive depending upon the classification system being discussed.

Time the record covers
At least 110 million years on record.
The record covers at least 113.2 Mya to 2.58 Mya. No occurrence read is dated outside 174.7 Mya to 129 ka.
2,799 occurrences of Magnoliopsida on record, most of them in the Eocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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
2,799 occurrences- Middle Jurassicunder 1%
- Late Jurassicunder 1%
- Early Cretaceous4%
- Late Cretaceous18%
- Paleocene25%
- Eocene38%
- Oligocene3%
- Miocene10%
- Plioceneunder 1%
- Pleistocene1%
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 at least 803 sites for Magnoliopsida, 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.
