Phyllodus

Phyllodus is an extinct genus of bony fish from the Maastrichtian to Middle Miocene. Fossils of the genus have been found in the Maastrichtian to Danian Hell Creek Formation, the Eocene London Clay, the Early eocene Nanjemoy formation. and the Paleocene of South Carolina.

Time the record covers

At least 55 million years on record.

The record covers at least 72.2 Mya to 16.3 Mya. No occurrence read is dated outside 83.6 Mya to 12.5 Mya.

28 occurrences of Phyllodus on record, most of them in the Eocene. 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

28 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 26 sites for Phyllodus, 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.

19 references

Each of the 28 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. 7 further references are not listed. 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.
