Pontosphaera
Searched as Pontosphaera exilisi. The Paleobiology Database treats Pontosphaera as the accepted name.
No picture of Pontosphaera was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Pontosphaera, or no answer at all. This entry cannot say which.

Time the record covers
At most 4.4 million years on record.
The one occurrence read is dated to somewhere between 66 Mya and 61.66 Mya, which is a dating window rather than a span.
1 occurrence of Pontosphaera 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
1 occurrences- Paleocene100%
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 at least 1,472 sites for Pontosphaera, and this reads 240 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.
