Time the record covers

At most 1.7 million years on record.

Every occurrence read is dated to somewhere between 1.8 Mya and 129 ka, and nothing in the dating separates them, so that window is what the record shows rather than a span.

7 occurrences of Argyrotheca barrettiana on record, most of them in the Pleistocene. 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

7 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.

No 3D scan of Argyrotheca barrettiana was found in Sketchfab.

Smithsonian Open Access and MorphoSource were not reached for this taxon, so this list is what the others held rather than everything there is.

This is what the site found, which is not the same as what exists.
