Eudinoceras
Eudinoceras is an extinct genus of pantodont in the family Coryphodontidae. The first fossils were discovered in the Irdin Manha Formation by palaeontologists Henry Fairfield Osborn and Roy Chapman Andrews in 1923, and were assigned to the genus Eudinoceras, due to both thinking it was a dinoceratan closely related to Dinoceras. As more complete specimens were recovered, the animal was identified as a pantodont more related to the genus Coryphodon.

Time the record covers
At least 10 million years on record.
The record covers at least 48.07 Mya to 37.71 Mya. No occurrence read is dated outside 56 Mya to 33.9 Mya.
20 occurrences of Eudinoceras 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
20 occurrences- Eocene100%
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 18 sites for Eudinoceras, 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.
