However, Australia is known for its rich fossil record of diverse prehistoric bird species, including some that were quite large. Here are a few examples:
1. Genyornis: Genyornis newtoni, commonly called the "mihirung paringmal," was a giant flightless bird that lived in Australia during the Pleistocene epoch. It was one of the largest known birds, standing up to 2 meters (6.5 feet) tall and weighing over 200 kilograms (440 pounds).
2. Dromornis: Dromornis stirtoni, known as the "stirton's dromornithid," was another giant flightless bird from Australia. It lived during the Miocene and Pliocene epochs and was estimated to be around 2 meters (6.5 feet) tall, similar in size to Genyornis.
3. Progura: Progura gallinacea, also called the " Malleefowl," was a large ground-dwelling bird that lived in Australia during the Miocene and Pliocene epochs. While it was not as massive as Genyornis or Dromornis, it was still a substantial bird, weighing up to 10 kilograms (22 pounds).
4. Extinct Megapodes: Australia has a diverse history of megapodes, which are a group of ground-dwelling birds known for their mound-building nesting habits. Some extinct Australian megapodes, such as the giant malleefowl (Leipoa gallinacea) and the greater fowl (Megalaimis moorei), were larger than their modern counterparts.
These are just a few examples of prehistoric birds that once roamed Australia, showcasing the continent's rich biodiversity in the past. However, it's important to note that while some of these birds were large, they do not correspond to the mythical concepts of "thunder birds" found in folklore.
