Trivia arctica

Trivia arctica, the northern cowrie, is a species of small sea snail, a marine gastropod mollusc in the family Triviidae, the trivias. This is a similar species to Trivia monacha and it often occurs in the same areas. The name Trivia means "common" and the word arctica means "of the arctic".

7 occurrences of Trivia arctica on record, most of them in the Pleistocene. 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

7 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.

564 taxa

The Paleobiology Database records 7 sites for Trivia arctica, 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

4 references

Each of the 7 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. Each entry links to the Paleobiology Database's own record for the work.
