Pygope

Pygope is an extinct genus of brachiopods belonging to the family Pygopidae. These brachiopods lived in open sea from the Jurassic Period, Kimmeridgian age up to Cretaceous Period, Barremian age. Some of the species are characterised by a smaller or larger perforation through the entire shell in older specimens, while others just have a depression somewhere on the midline. Younger specimens of the perforated species develop a heart-shape and subsequently both extensions merge, thus encircling a central passage which is in fact entirely outside the shell.

162 occurrences of Pygope on record, most of them in the Late 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

162 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 162 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. 8 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.
