Archaeplastida
Archaeplastida or archaeplastids, sometimes also regarded as the kingdom Plantae sensu lato, are a large group of eukaryotes comprising the major clades Viridiplantae and Rhodophyta, as well as the minor basal division Glaucophyta. While the vast majority of archaeplastids are photosynthetic autotrophs, the group also includes heterotrophic lineages such as the predatorial (eukaryotrophic) flagellates Rhodelphidia, and probably also the microscopic picoplankton Picozoa, both may be sister to Rhodophyta and altogether forming the larger solid clade Rhodaria.

Time the record covers
At least 1597 million years on record.
The record covers at least 1600 Mya to 2.58 Mya. No occurrence read is dated outside 1800 Mya to 11.7 ka.
262 occurrences of Archaeplastida on record, most of them in the Miocene. 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.

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 200 sites for Archaeplastida, 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.

Each of the 262 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. 35 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.
