Corum
Smithsonian Institution · CC0 · via Smithsonian. May be a photograph of a specimen, or an artist’s reconstruction — an interpretation of a skeleton, since colour and soft tissue are almost never preserved.
On record
Recorded, not inferred- Sits inside
- PseudodictyomitridaePBDB
Time the record covers
At least 9.7 million years on record.
The record covers at least 237 Mya to 227.3 Mya. No occurrence read is dated outside 247 Mya to 174.7 Mya.
185 occurrences of Corum on record, most of them in the Late Triassic. 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
185 occurrences- Middle Triassic17%
- Late Triassic82%
- Early Jurassicunder 1%
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 Corum has been recovered from, largest first. Drawn where the rock is now, not where it formed. 23 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 88 sites for Corum, 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 185 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. 4 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.
