Cedrus

Cedrus is a small genus in the pine family, Pinaceae, consisting of 1-3 species of coniferous trees known in English as cedars. They are native to the mountains of the western Himalayas and the Mediterranean region at high altitudes. The trees grow tall with a cylindrical trunk and a wide leafy crown. The cones are erect; the leaves grow in tufts of 15–45 needle leaves, which can be bright green or blue-green with a waxy coat. When the cones are mature, they disintegrate to release the seeds, which are winged. Both pollen and seeds are wind-dispersed.

45 occurrences of Cedrus on record, most of them in the Pleistocene. 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

45 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.

516 taxa

The Paleobiology Database records 44 sites for Cedrus, 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.

Entered from

14 references

Each of the 45 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. 2 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.
