Brachyprion (Eomegastrophia)

Eomegastrophia ethica (Cocks, 1967), a relative of Brachyprion (Eomegastrophia) — not Brachyprion (Eomegastrophia) itself

Not Brachyprion (Eomegastrophia). This is Eomegastrophia ethica (Cocks, 1967), a relative — both are Leptostrophiidae.

Time the record covers

At least 1.9 million years on record.

The record covers at least 440.5 Mya to 438.6 Mya. No occurrence read is dated outside 443.1 Mya to 432.9 Mya.

91 occurrences of Brachyprion (Eomegastrophia) 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

91 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.

41 taxa

The Paleobiology Database records 46 sites for Brachyprion (Eomegastrophia), 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.

1 reference

Each of the 91 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.
