Time the record covers
At least 27 million years on record.
The record covers at least 61.66 Mya to 33.9 Mya. No occurrence read is dated outside 66 Mya to 27.3 Mya.
142 occurrences of Nemocardium (Nemocardium) linteum on record, most of them in the Eocene. 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
142 occurrencesThese 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 134 sites for Nemocardium (Nemocardium) linteum, 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.
