Garjainia

Garjainia is an extinct genus of erythrosuchid archosauriform reptile from the Olenekian of Russia and South Africa. It contains two species, Garjainia prima, from the Yarengian/Yarkenskian Supergorizont of Russia, and Garjainia madiba, from the Burgersdorp Formation of South Africa. "Vjuskovia triplicostata", a name assigned to some erythrosuchid fossils from Russia, has been synonymized with Garjainia prima.

Time the record covers

At most 3.8 million years on record.

Every occurrence read is dated to somewhere between 250.8 Mya and 247 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

18 occurrences of Garjainia 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

18 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.

34 taxa

The Paleobiology Database records 18 sites for Garjainia, 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.

4 references

Each of the 18 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.
