Exbucklandia

Exbucklandia is a genus of flowering plants in the family Hamamelidaceae. They are medium to large trees whose natural range is from eastern India through southern China and southward through the Malay Peninsula. In India and China, they are widely cultivated for their impressive foliage and valuable lumber. A few have been grown in the southernmost parts of the United States. To speakers of English, Exbucklandia is generally known as the Pipli tree, from the Bengali name for the species Exbucklandia populnea.

6 occurrences of Exbucklandia 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

6 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 5 sites for Exbucklandia, 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.

Entered from

6 references

Each of the 6 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.
