Credneria

Credneria is an extinct genus in the family or Platanaceae of broad-leaf trees similar to extinct Platanus species that appeared during the Cretaceous. The genus was first described by Zenker (1833) and has formerly been placed in the family Salicaceae rather than Platanaceae on occasion. Credneria leaves are preserved in sandstone and less often in siltstone. The leaves are typically obovate with a pinnate-actinodromous venation and distinct suprabasal veins.

Time the record covers

At least 45 million years on record.

The record covers at least 93.9 Mya to 48.07 Mya. No occurrence read is dated outside 100.5 Mya to 37.71 Mya.

11 occurrences of Credneria on record, most of them in the Paleocene. 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.

119 taxa

The Paleobiology Database records 8 sites for Credneria, 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

4 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.
