Coleoloides

Searched as Coleoloides multistriata. The Paleobiology Database treats Coleoloides as the accepted name.

Coleoloides, or the coleolids, are a genus of Cambrian small shelly fossils with an aragonite skeleton. They were first described in 1889 by Charles Doolittle Walcott as members of the pteropods. Their affinity is unknown but they were probably produced by an organism of the annelid grade of complexity. Calcium carbonate fossils of coleolids have been found at Newfoundland clustered together, oriented vertically.

No picture of Coleoloides 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 Coleoloides, or no answer at all. This entry cannot say which.

Time the record covers

At most 9.7 million years on record.

The one occurrence read is dated to somewhere between 516.2 Mya and 506.5 Mya, which is a dating window rather than a span.

1 occurrence of Coleoloides 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

1 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 40 sites for Coleoloides, 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

1 reference

Each of the 1 occurrence 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. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
