Architectonica (Stellaxis) cognata

Architectonica cognata (Gabb, 1864), a relative of Architectonica (Stellaxis) cognata — not Architectonica (Stellaxis) cognata itself

Not Architectonica (Stellaxis) cognata. This is Architectonica cognata (Gabb, 1864), a relative — both are Architectonicidae.

30 occurrences of Architectonica (Stellaxis) cognata 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

30 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.

10 references

Each of the 30 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. 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.
