Reconstructed from fossilized leaves found in Victoria, Baiera australis remains a pivotal taxon for understanding Cretaceous gymnosperm evolution. Originally described by McCoy in 1892, this species represents the basionym for the widely recognized southern ginkgo fossil, Ginkgo australis. Its preservation in coal measures provides critical data on the prehistoric vegetation of South Gippsland.
Specimens demonstrate robust, deeply cleft leaves with a prominent petiole. The lamina divides repeatedly into narrow, wedge-shaped lobes, each containing parallel dichotomous veins. Cuticular analyses of related specimens suggest a thick cuticle with haplocheilic stomata, suggesting a resilience to fluctuating atmospheric conditions during the Mesozoic.
This fossil species provides valuable insights into the geographical distribution of the Ginkgoaceae family during the Mesozoic era. Notable details include:
