Sekwicyathus nahanniensis

Sekwicyathus is a genus of Archaeocyathan poriferan. Archaeocyaths are a taxon of extinct organism that lived in warm, tropical waters during the Early Cambrian period and built reef-like structures in the oceans. They are cup-shaped, with internal and external walls that form a filter feeding system. It is unclear as to whether Archaeocyaths are animals, plants, or some other type of organism. They are similar to modern-day sponges but share traits with other organisms as well. There are 309 discovered genera of Archaeocyaths.

No picture of Sekwicyathus nahanniensis was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Sekwicyathus nahanniensis, or no answer at all. This entry cannot say which.

Time the record covers

At most 8.9 million years on record.

Every occurrence read is dated to somewhere between 521 Mya and 512.1 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

5 occurrences of Sekwicyathus nahanniensis on record, most of them in the Cambrian. 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

5 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 5 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. 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.
