Sclerorhynchidae

Ganopristidae is an extinct family of cartilaginous fish from the Cretaceous belonging to the suborder Sclerorhynchoidei. While the name Sclerorhynchidae is often used for this family, it is a junior synonym of Ganopristidae. This family contains the genera Libanopristis, Micropristis, and Sclerorhynchus. The type genus Ganopristis is considered to be a junior synonym of Sclerorhynchus.

Time the record covers

At least 65 million years on record.

The record covers at least 121.4 Mya to 56 Mya. No occurrence read is dated outside 143.1 Mya to 33.9 Mya.

413 occurrences of Sclerorhynchidae on record, most of them in the Late Cretaceous. 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

413 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 413 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. 164 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.
