Macluritidae

Macluritidae is an extinct family of relatively large, Lower Ordovician to Devonian, macluritacean gastropods, coiled, that is dextral while appearing sinistral, of which the genus Maclurites is arch-typical. The base of their shells is flat or gently protruding while the upper side is generally concave.

Time the record covers

At least 38 million years on record.

The record covers at least 483.4 Mya to 445.2 Mya. No occurrence read is dated outside 488.9 Mya to 443.1 Mya.

532 occurrences of Macluritidae on record, most of them in the Ordovician. 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

532 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.

Each of the 532 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. 144 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.
