Corbisema inermis
No picture of Corbisema inermis was found. Wikidata and iDigBio were searched and had none. GBIF was not searched: the Paleobiology Database does not place Corbisema inermis firmly enough to tell it from something else bearing the same name, and a search on the name alone returns whichever of them was photographed. Wikipedia and Smithsonian Open Access did not answer, so this is what the others held rather than everything there is.

Time the record covers
At least 17 million years on record.
The record covers at least 66 Mya to 48.07 Mya. No occurrence read is dated outside 72.2 Mya to 37.71 Mya.
12 occurrences of Corbisema inermis on record, most of them in the Paleocene. 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
12 occurrences- Late Cretaceous33%
- Paleocene58%
- Eocene8%
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 11 sites for Corbisema inermis, 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.
Entered from
2 references- Upper Cretaceous and lower Paleocene diatom and silicoflagellate biostratigraphy of Seymour Island, eastern Antarctic Peninsula11
- Correlation of the middle Eocene Kellogg Shale of northern California1
Each of the 12 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. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
