Eucryphia falcata is an extinct species of flowering plant. It belongs to the genus Eucryphia within the family Cunoniaceae.[1]
Description
Macrofossils of compound leaves with an unknown number of total leaflets have been found. The lateral leaflets are falcate, and the terminal leaflet is symmetrical. It has a rounded base. The leaf margin had serrations.[2] This is likely the plesiomorphic condition for all genera of the family Cunoniaceae.[3] The leaves also had trichomes.[2]
Etymology
The specific epithet falcata is derived from the falcate, lateral leaflets of the compound leaves.[2]
Temporal range
This species lived during the late Paleocene, during the timeframe of 58.7 to 55.8 Ma.[2][4][5] It is the oldest fossil Eucryphia species.[3][6]
Distribution
One fossil specimen has been found near Bunyan, New South Wales, Australia.[1] The fossil was found in lake sediments of the Lake Bungarby,[2] which is a terrestrial mudstone dating back to the Paleocene.[5]
