Cedrelospermum

Cedrelospermum is an extinct genus of plants in the family Ulmaceae. Its fossils have been found in the early Eocene to early Oligocene strata in North America, in the middle Eocene to middle Miocene strata in Europe, and in the middle Eocene of Bangor in Tibet, the late Eocene of Nyima, the late Oligocene of Shuanghu, and the late Eocene of Maguan in Yunnan in Asia.

27 occurrences of Cedrelospermum on record, most of them in the Eocene. 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

27 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.

318 taxa

The Paleobiology Database records 15 sites for Cedrelospermum, 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.

8 references

Each of the 27 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.
