Razumovskia sp.

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

Time the record covers

At least 19 million years on record.

The record covers at least 516 Mya to 497 Mya. No occurrence read is dated outside 521 Mya to 477.1 Mya.

17 occurrences of Razumovskia sp. on record, most of them in the Cambrian. 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

17 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 Paleobiology Database records 9 sites for Razumovskia sp., 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

10 references

Each of the 17 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.
