Phosphuga atrata
Phosphuga is a Eurasian genus of flightless carrion beetle, whose sole member is the species Phosphuga atrata, commonly known as black snail beetle. Up to 15mm long, they have an oval shape as adults and are brownish in color when newly moulted, becoming black as their exoskeleton hardens. Black snail beetles resemble the type genus Silpha of the carrion beetle subfamily Silphinae, and are thus placed in tribe Silphini. Although they range widely, they are seldom encountered by people, because they hunt at night and hide during the day, often under bark.

Time the record covers
At most 645 thousand years on record.
Every occurrence read is dated to somewhere between 774 ka and 129 ka, and nothing in the dating separates them, so that window is what the record shows rather than a span.
5 occurrences of Phosphuga atrata on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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
5 occurrences- Pleistocene100%
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 5 sites for Phosphuga atrata, 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.
