Allonema

No picture of Allonema was found. Wikidata and Smithsonian Open Access were searched and had none. iDigBio and GBIF were not searched: the Paleobiology Database does not place Allonema 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. Wikipedia did not answer, so this is what the others held rather than everything there is.

Time the record covers

At least 231 million years on record.

The record covers at least 468 Mya to 237 Mya. No occurrence read is dated outside 477.1 Mya to 233.6 Mya.

63 occurrences of Allonema on record, most of them in the Devonian. 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

63 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.

748 taxa

The Paleobiology Database records 41 sites for Allonema, 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 63 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.

No picture of Allonema was found. Wikidata and Smithsonian Open Access were searched and had none.

iDigBio and GBIF were not searched: the Paleobiology Database does not place Allonema 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.

Wikipedia did not answer, so this is what the others held rather than everything there is.

No 3D scan was found. Smithsonian Open Access, MorphoSource and Sketchfab were all searched.

This is what the site found, which is not the same as what exists.
