Ateleaspis

Searched as Ateleaspis robustus. The Paleobiology Database treats Ateleaspis as the accepted name.

Ateleaspis is an extinct genus of primitive ostracoderm fish that lived in the Silurian period to the Lower Devonian. Like other ostracoderms, Ateleaspis had a head shield similar to that of Cephalaspis. Species from Silurian period were found in Norway and Scotland, but now has been found also in Siberia from Early Devonian period.

Time the record covers

At most 1.9 million years on record.

The one occurrence read is dated to somewhere between 428.6 Mya and 426.7 Mya, which is a dating window rather than a span.

1 occurrence of Ateleaspis on record, most of them in the Silurian. 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.
