Laugia
Laugia is an extinct genus of coelacanth fish which lived during the Induan age of the Early Triassic epoch in what is now Greenland. The type and only species, Laugia groenlandica, was collected from the Wordie Creek Formation and described by Erik Stensiö. The genus is named after Lauge Koch.

Time the record covers
At most 802 thousand years on record.
Every occurrence read is dated to somewhere between 251.902 Mya and 251.1 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
5 occurrences of Laugia 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
5 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 4 sites for Laugia, 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.

Each of the 5 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. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
