Ichthyopterygia

Ichthyopterygia was a designation introduced by Sir Richard Owen in 1840 to designate the Jurassic ichthyosaurs that were known at the time, but the term is now used more often for both true Ichthyosauria and their more primitive early and middle Triassic ancestors.

Time the record covers

At least 148 million years on record.

The record covers at least 248.6 Mya to 100.5 Mya. No occurrence read is dated outside 251.902 Mya to 66 Mya.

690 occurrences of Ichthyopterygia on record, most of them in the Early Jurassic. 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

690 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 690 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. 349 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.
