Zby atlanticus

Zby is an extinct genus of turiasaurian sauropod dinosaur known from the Late Jurassic, particularly late Kimmeridgian stage of the Lourinhã Formation, in central west Portugal. It contains a single species, Zby atlanticus. It is named after Georges Zbyszewski, who studied the geology and paleontology of Portugal.

Time the record covers

At most 3.1 million years on record.

Every occurrence read is dated to somewhere between 152.21 Mya and 149.2 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

2 occurrences of Zby atlanticus on record, most of them in the Late Jurassic. 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

2 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.

The Paleobiology Database records 2 sites for Zby atlanticus, 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.
