Leaf fossils of Luzuriaga and a monocot flower with in situ pollen of Liliacidites contortus Mildenh. & Bannister sp. nov. (Alstroemeriaceae) from the Early Miocene
• Premise of the study: The Foulden Maar lake sediments in Otago, South Island, New Zealand, date to the earliest Miocene and provide an important picture of the diversity of the Australasian biota, paleoecology, and climate at a time when New Zealand had a smaller land area than today.
