Eczematolepis
Eczematolepis is an extinct genus of ptyctodontidan from the Milwaukee Formation of Wisconsin. Three species are known: E. fragilis, E. pustulosus and E. telleri. It was originally classified as the genus Acantholepis but that name was preoccupied.

Time the record covers
At most 5.7 million years on record.
The one occurrence read is dated to somewhere between 387.95 Mya and 382.31 Mya, which is a dating window rather than a span.
1 occurrence of Eczematolepis 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- Devonian100%
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.
