Guarea sp.
Guarea is a genus of evergreen trees or shrubs in the family Meliaceae, native to tropical Africa and Central and South America. At their largest, they are large trees 20–45 m tall, with a trunk over 1 m diameter, often buttressed at the base. The leaves are pinnate, with 4–6 pairs of leaflets, the terminal leaflet present. They are dioecious, with male and female flowers on separate plants. The flowers are produced in loose inflorescences, each flower small, with 4–5 yellowish petals. The fruit is a four or five-valved capsule, containing several seeds, each surrounded by a yellow-orange fleshy aril; the seeds are dispersed by hornbills and monkeys which eat the aril.

Time the record covers
At least 17 million years on record.
The record covers at least 23.04 Mya to 5.333 Mya. No occurrence read is dated outside 33.9 Mya to 2.58 Mya.
5 occurrences of Guarea sp. on record. 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 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 5 sites for Guarea sp., 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.

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 doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
