Cyphaspis

Searched as Cyphaspis hoepfneri hoepfheri. The Paleobiology Database treats Cyphaspis as the accepted name.

Cyphaspis is a genus of small, proetid trilobite that lived from the Late Ordovician to the Late Devonian. Fossils have been found in marine strata in what is now Europe, Africa and North America. Various species had a compact body, and a large, bulbous glabellum. Many species had long spines arranged similarly to closely related genera, such as Otarian, Otarionella, Chamaeleoaspis, and Namuropyge.

Time the record covers

At most 5.6 million years on record.

The one occurrence read is dated to somewhere between 393.47 Mya and 387.95 Mya, which is a dating window rather than a span.

1 occurrence of Cyphaspis on record, most of them in the Devonian. 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

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 97 sites for Cyphaspis, 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.
