Mesocena

No picture of Mesocena was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was not searched: the Paleobiology Database does not place Mesocena firmly enough to tell it from something else bearing the same name, and a search on the name alone returns whichever of them was photographed.

Time the record covers

At least 11 million years on record.

The record covers at least 13.82 Mya to 2.58 Mya. No occurrence read is dated outside 23.04 Mya to 11.7 ka.

52 occurrences of Mesocena on record. 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

52 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 named rock units Mesocena has been recovered from, largest first. Drawn where the rock is now, not where it formed. 49 occurrences have no formation on record, which is common for older literature.

Found in the same rock

322 taxa

The Paleobiology Database records 40 sites for Mesocena, 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

6 references

Each of the 52 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.
