Trochomphalus dimidiatus
No picture of Trochomphalus dimidiatus 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 Trochomphalus dimidiatus, or no answer at all. This entry cannot say which.

Time the record covers
At least 300 thousand years on record.
The record covers at least 445.5 Mya to 445.2 Mya. No occurrence read is dated outside 449.6 Mya to 443.1 Mya.
3 occurrences of Trochomphalus dimidiatus 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
3 occurrences- Ordovician100%
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 3 sites for Trochomphalus dimidiatus, 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
2 references- Paleozoic Gastropod, Rostroconch, Helcionelloid and Tergomyan Database (2006 - 2023)2
- Koken and Perner, 19251
Each of the 3 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.
