Tristania

Tristania is a monotypic genus of flowering plants native to New South Wales, Australia, closely related to Thaleropia. The genus had a number of species, but some have been reclassified as Lophostemon and Tristaniopsis. The sole species currently in the genus is Tristania neriifolia. It is commonly known as the water gum. The genus is named for the French botanist Jules Marie Claude de Tristan (1776–1861).

Time the record covers

At most 51 million years on record.

Every occurrence read is dated to somewhere between 66 Mya and 15.98 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

5 occurrences of Tristania on record, most of them in the Oligocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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

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 3 sites for Tristania, 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.

2 references

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. Each entry links to the Paleobiology Database's own record for the work.
