Time the record covers

At least 33 million years on record.

The record covers at least 33.9 Mya to 129 ka. No occurrence read is dated outside 56 Mya to 0 Mya.

134 occurrences of Psammotreta (Leporimetis) 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.

When

134 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 named rock units Psammotreta (Leporimetis) has been recovered from, largest first. Drawn where the rock is now, not where it formed. 8 further formations hold fewer occurrences each and are not listed. 16 occurrences have no formation on record, which is common for older literature.

Found in the same rock

2,095 taxa

The Paleobiology Database records 120 sites for Psammotreta (Leporimetis), and this reads all of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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

49 references

Each of the 134 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. 37 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 Psammotreta (Leporimetis) 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.
