Sphaerirhynchia

A picture published with the record for Sphaerirhynchia.

Yale Peabody Museum · CC0 · via GBIF. May be a photograph of a specimen, or an artist’s reconstruction — an interpretation of a skeleton, since colour and soft tissue are almost never preserved.

Time the record covers

At least 25 million years on record.

The record covers at least 438.6 Mya to 413.02 Mya. No occurrence read is dated outside 443.1 Mya to 410.62 Mya.

169 occurrences of Sphaerirhynchia on record, most of them in the Silurian. 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

169 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.

Found in the same rock

1,262 taxa

The Paleobiology Database records 152 sites for Sphaerirhynchia, 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

58 references

Each of the 169 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. 46 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.
