Biomphalaria choanomphala
Biomphalaria choanomphala is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod in the family Planorbidae, the ram's horn snails. Biomphalaria choanomphala has a discoidal, brownish-yellow shell with an approximate shell diameter of 6–10 mm. Biomphalaria choanomphala is a medically important pest, due to it being an intermediate host of the intravascular trematode genus, Schistosoma.

Time the record covers
At most 129 thousand years on record.
Every occurrence read is dated to somewhere between 129 ka and 0 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
2 occurrences of Biomphalaria choanomphala on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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- Pleistocene50%
- Holocene50%
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 2 sites for Biomphalaria choanomphala, 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
1 referenceEach 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.
