Yeneen houssayi

Yeneen is an extinct genus of titanosaurian sauropod dinosaurs known from the Late Cretaceous Bajo de la Carpa Formation of Argentina. The genus contains a single species, Yeneen houssayi, known from at least one partial skeleton. Its discovery highlights the diversity of titanosaurs in this formation, which also includes Bonitasaura, Inawentu, Overosaurus, Rinconsaurus, and Traukutitan.

Time the record covers

At most 2.1 million years on record.

The one occurrence read is dated to somewhere between 85.7 Mya and 83.6 Mya, which is a dating window rather than a span.

1 occurrence of Yeneen houssayi on record, most of them in the Late Cretaceous. 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

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 1 site for Yeneen houssayi, 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.
