Dyscritella

Dyscritella is an extinct genus of trepostome bryozoan that was highly successful in the late Triassic period, re-colonizing high latitudes in the northern hemisphere after the extinction of earlier bryozoan genera. Dyscritella was an "ecological opportunist" and widely distributed, found in every climatic belt.

Time the record covers

At least 204 million years on record.

The record covers at least 410.62 Mya to 205.7 Mya. No occurrence read is dated outside 413.02 Mya to 201.4 Mya.

364 occurrences of Dyscritella on record, most of them in the Permian. 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

364 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.

Each of the 364 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. 85 further references are not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
