Pleurodira

Searched as Pleurodira indet.. The Paleobiology Database treats Pleurodira as the accepted name.

The Pleurodira are one of the two living suborders of turtles more known commonly as the side-necked turtles. The name "Pleurodira" translates to "side neck", whereas the Cryptodira are known as hidden-necked turtles; these names reflect the distinct neck retraction mechanisms between the two suborders, which are the product of diverging evolutionary histories. Within the Pleurodira, three living families are represented: Chelidae, the Austro-South American side-necked turtles, the Pelomedusidae, the African mud terrapins, and the Podocnemididae, the American side-neck river turtles.

49 occurrences of Pleurodira on record, most of them in the Late Cretaceous. The Paleobiology Database records this as a living group. 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

49 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 839 sites for Pleurodira, 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.

27 references

Each of the 49 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. 15 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.
