Jegorovaia expansa
No picture of Jegorovaia expansa was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Jegorovaia expansa, or no answer at all. This entry cannot say which.

Time the record covers
At least 500 thousand years on record.
The record covers at least 491.5 Mya to 491 Mya. No occurrence read is dated outside 495.2 Mya to 486.85 Mya.
18 occurrences of Jegorovaia expansa 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
18 occurrences- Cambrian100%
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 1 site for Jegorovaia expansa, and this reads all of them. The number is how many of those sites it was catalogued from too.
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
3 references- Cambrian Malyy Karatau Range, Kazakhstan15
- The Cambrian trilobites of western Zhejiang2

Each of the 18 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. Each entry links to the Paleobiology Database's own record for the work.
