Aulopus

Aulopus is a genus of flagfins native to the Atlantic Ocean and the Pacific Ocean. Although Aulopus is native to both the Atlantic and the Pacific oceans, for the first time in 2010 Aulopus filamentosus, was spotted in Brazilian waters. A discovery like this may suggest that these fish can be found in new environments.

7 occurrences of Aulopus on record, most of them in the Eocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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.

101 taxa

The Paleobiology Database records 7 sites for Aulopus, 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

2 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.
