Time the record covers
At least 382 million years on record.
The record covers at least 382.31 Mya to 129 ka. No occurrence read is dated outside 393.47 Mya to 0 Mya.
4,791 occurrences of Equisetophyta on record, most of them in the Early Cretaceous. 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 named rock units Equisetophyta has been recovered from, largest first. Drawn where the rock is now, not where it formed. 617 further formations hold fewer occurrences each and are not listed. 1,362 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records at least 1,121 sites for Equisetophyta, 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 4,791 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. 687 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.

No 3D scan of Equisetophyta was found in Sketchfab.
Smithsonian Open Access and MorphoSource were not reached for this taxon, so this list is what the others held rather than everything there is.
This is what the site found, which is not the same as what exists.
