Monopleuridae

Monopleuridae is a family of bivalves that belongs to the order Hippuritida (rudists). Some genera such as Monopleura are known to have a global distribution with a wide temporal range from the Tithonian age of the Jurassic period to the Maastrichtian age of the Cretaceous period.

Time the record covers

At least 60 million years on record.

The record covers at least 132.6 Mya to 72.2 Mya. No occurrence read is dated outside 137.05 Mya to 66 Mya.

122 occurrences of Monopleuridae on record, most of them in the Early 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

122 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.

941 taxa

The Paleobiology Database records 71 sites for Monopleuridae, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

44 references

Each of the 122 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. 32 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. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
