Paleobotanic Barbara Waigstaff led by the International Scientists team for the first time reconstructed the prehistoric forests of Australia, where polar dinosaurs lived. The focal point was the microscopic disagreements and cholds removed from the breeds where the bones of the ancient lizards were. Published in İş Magazine Alcheringa: Journal of Australasia Paleontology.
140-100 million years ago, the modern Australian region was in the South – almost South Pole. Despite the harsh climate, dinosaurs lived here – and they developed.
This data opens an incredible stage in the history of the world – an early chalk period, one of the hottest ones for the last half billion years. Due to the active volcanic activity, the level of carbon dioxide in the atmosphere was high, which led to the lack of polar ice caps and a global rise in the sea. At that time, the super continent of Gondwan began to leave and was at high latitudes in the south of Australia.
The dinosaurs living in this region contained both beaks and teeth and herbivores and predatory teropods. They wandered in the forests that survived a dramatic transformation for millions of years.
The study showed: About 132 million years ago, blooming plants appeared in these latitudes. At first they were rare, but spread rapidly to the world – and this planet changed the ecosystems. Flowering plants, algae, plans, and especially for the old bush species, including erase herbs that cannot compete in a new, warm climate.
100 million years ago, Victoria forests, seed fern, remaining ordinary fern herbs, as well as mosses occupying new ecological niches and floral plants were open coniferous crowns where they grew.
These findings are particularly important when the planet experiences heating again. Understanding how life reacts to climate changes in the past helps to better imagine what expects us in the future.
