Stenodiscus

Stenodiscus is an extinct genus of bryozoan of the family Stenoporidae, known from the Carboniferous to the Upper Permian periods. Its colonies were large and could be encrusting, massive, or branching, sometimes made of multiple layers of growth over themselves, and usually possessed monticules with abundant large acanthostyles.

No picture of Stenodiscus was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Stenodiscus, or no answer at all. This entry cannot say which.

At least 76 million years on record.

The record covers at least 330.3 Mya to 254.14 Mya. No occurrence read is dated outside 358.86 Mya to 251.902 Mya.

53 occurrences of Stenodiscus 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

53 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 42 sites for Stenodiscus, 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.

Entered from

26 references

Each of the 53 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. 14 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. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
