Corumbella

Corumbella is an extinct genus of terminal-Ediacaran animals. It is the only genus in the monotypic family Corumbellidae, and is represented by a single species Corumbella werneri. It possessed a carapace made up of thick polygonal rings in which plates with pores and papillae attest to the advent of skeletogenesis in the latest Neoproterozoic metazoan. It was sessile and somewhat resembles the later conulariids, though this similarity is likely superficial; its secretion of an aragonitic scleritome suggests a eumetazoan affinity.

Time the record covers

At most 97 million years on record.

Every occurrence read is dated to somewhere between 635 Mya and 538.8 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

17 occurrences of Corumbella on record. 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

17 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 17 sites for Corumbella, 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.

12 references

Each of the 17 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.
