Tetradium

No picture of Tetradium was found. iDigBio and Smithsonian Open Access were searched and had none. Wikipedia and Wikidata have a picture filed under this name, but nothing tied it to Tetradium itself, so it was not used. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Tetradium, or no answer at all. This entry cannot say which.

Time the record covers

At least 8.7 million years on record.

The record covers at least 458.2 Mya to 449.5 Mya. No occurrence read is dated outside 471.3 Mya to 443.1 Mya.

224 occurrences of Tetradium on record, most of them in the Ordovician. 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

224 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 Tetradium has been recovered from, largest first. Drawn where the rock is now, not where it formed. 29 further formations hold fewer occurrences each and are not listed. 42 occurrences have no formation on record, which is common for older literature.

873 taxa

The Paleobiology Database records 165 sites for Tetradium, 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

43 references

Each of the 224 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. 31 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.
