Dinomischus
Dinomischus is an extinct genus of stalked filter-feeding animals within the Cambrian period, with specimens known from the Burgess Shale, the Maotianshan Shales, the Kaili Formation and the Marjum Formation. While long of uncertain affinities, recent studies have suggested it to be a stem-group ctenophore.

Time the record covers
At least 9.5 million years on record.
The record covers at least 516 Mya to 506.5 Mya. No occurrence read is dated outside 521 Mya to 497 Mya.
10 occurrences of Dinomischus on record, most of them in the Cambrian. 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
10 occurrences- Cambrian100%
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 8 sites for Dinomischus, 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.
