Bitterwood Tree

First described in the mid-20th century, Ginkgoites waarrensis stands as a notable fossil taxon from the Mesozoic deposits of Victoria. This species contributes to our understanding of high-latitude vegetation in the southern hemisphere during the Mesozoic era. Its discovery highlights the global distribution of the Ginkgoales lineage.
The fossil leaves are characterized by a fan-shaped structure with moderate lobing along the upper margin. Fine, parallel dichotomous venation is visible across the carbonaceous film left by the leaf blade. The overall dimensions and leaf margin division distinguish it from related species in the region.
Epidermal structures preserved in the fossils show stomata arranged in files. These cellular features resemble those found in other Mesozoic ginkgophytes but display unique dimensions that justify its classification as a distinct species.
