Urosoma hirudo
No picture of Urosoma hirudo 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 Urosoma hirudo, or no answer at all. This entry cannot say which.

Time the record covers
At least 18 million years on record.
The record covers at least 445.5 Mya to 426.7 Mya. No occurrence read is dated outside 449.6 Mya to 422.7 Mya.
2 occurrences of Urosoma hirudo 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
2 occurrences- Ordovician50%
- Silurian50%
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.

No other named taxon is catalogued from any of those sites.
The Paleobiology Database records 2 sites for Urosoma hirudo, and this reads all of them.
Entered from
2 references- A field guide to the Silurian Echinodermata of the British Isles: Part 1 - Eleutherozoa and Rhombifera1
- New classification of the "Heterocrinidae"1
Each of the 2 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.
