Kuehneosaurus

Kuehneosaurus is an extinct genus of Late Triassic kuehneosaurid reptile known from the Late Triassic of the Penarth Group of southwest England and the Steinmergel Group of Luxembourg. Temperature at this stage and region would have ranged from 28 to 35 °C. It was named by Pamela Lamplugh Robinson in 1962 in honour of paleontologist Walter Georg Kühne, and the type and only species is Kuehneosaurus latus. Measuring 72 centimetres long, it had "wings" formed from ribs which jutted out from its body by as much as 14.3 cm, connected by a membrane which allowed it to slow its descent when jumping from trees. It is a member of a family of extinct gliding reptiles, the Kuehneosauridae, within a larger living group the Lepidosauromorpha, which contain modern lizards and tuatara.

11 occurrences of Kuehneosaurus on record, most of them in the Late Triassic. 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

11 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 11 sites for Kuehneosaurus, 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.

5 references

Each of the 11 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. 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.
