Mystriosuchus
Mystriosuchus is an extinct genus of phytosaur that lived in the Late Triassic in Europe and Greenland. It was first named by Eberhard Fraas in 1896, and includes four species: M. planirostris, M. westphali, M. steinbergeri, and M. alleroq.

Time the record covers
At least 9.7 million years on record.
The record covers at least 211.18 Mya to 201.4 Mya. No occurrence read is dated outside 227.3 Mya to 199.5 Mya.
12 occurrences of Mystriosuchus on record, most of them in the Late 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
12 occurrencesThese 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 10 sites for Mystriosuchus, 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.
