Peltura
Peltura is a genus of trilobites from the Upper Cambrian. The type specimen of Peltura scarabaeoides, the type species of the genus, was discovered in the Alum Shale Formation of Sweden and first described by the Swedish naturalist Göran Wahlenberg in 1818. Species of this genus have now been found throughout the Scandinavian and Baltic regions.

Time the record covers
At least 2.6 million years on record.
The record covers at least 493.6 Mya to 491 Mya. No occurrence read is dated outside 497 Mya to 477.1 Mya.
38 occurrences of Peltura 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
38 occurrences- Cambrian95%
- Ordovician5%
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 30 sites for Peltura, 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.
