Claraia
Searched as Claraia fukianensis minor. The Paleobiology Database treats Claraia as the accepted name.
Claraia is an extinct genus of scallop-like bivalve molluscs that lived from the Capitanian stage of the Middle Permian to the Anisian stage of the Middle Triassic, 266-237 million years ago. Fossils have been found worldwide in North America, Europe, Asia, Africa, and Australia. These are common fossils subsequent to the Permian-Triassic boundary, suggesting that the genus experienced rapid diversification during and after the Permian–Triassic extinction event, around 251.9 million years ago, making it a disaster taxon.

Time the record covers
At most 802 thousand years on record.
The one occurrence read is dated to somewhere between 251.902 Mya and 251.1 Mya, which is a dating window rather than a span.
1 occurrence of Claraia on record, most of them in the Early Triassic. 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
1 occurrences- Early Triassic100%
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 791 sites for Claraia, and this reads 240 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.
