Baenidae

Baenidae is an extinct family of paracryptodiran turtles known from the Early Cretaceous to the Eocene of North America. The name of the type genus, Baena, appears to be of Native American origin, likely from the Arapaho be’enoo. They are primarily found in freshwater deposits, and are considered to be aquatic, with a largely generalist habit.

Time the record covers

At least 97 million years on record.

The record covers at least 143.1 Mya to 45.9 Mya. No occurrence read is dated outside 154.8 Mya to 37.71 Mya.

606 occurrences of Baenidae 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

606 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.

The Paleobiology Database records 462 sites for Baenidae, and this reads 240 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.

Each of the 606 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. 119 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.
