Nemocardium (Nemocardium)
No picture of Nemocardium (Nemocardium) was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Nemocardium (Nemocardium), or no answer at all. This entry cannot say which.

Time the record covers
At least 107 million years on record.
The record covers at least 113.2 Mya to 5.333 Mya. No occurrence read is dated outside 121.4 Mya to 2.58 Mya.
234 occurrences of Nemocardium (Nemocardium) on record, most of them in the Eocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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
234 occurrences- Early Cretaceous1%
- Late Cretaceous1%
- Paleocene17%
- Eocene48%
- Oligocene29%
- Miocene3%
- Plioceneunder 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 Paleobiology Database records 185 sites for Nemocardium (Nemocardium), 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 234 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. 43 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.

Smithsonian Open Access was 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.
