Ancient Trilobites Unravel Geographic Mystery

Ten newly discovered species of trilobites, ancient arthropods that lived nearly 490 million years ago, may hold the key to understanding Thailand's position on the former supercontinent Gondwana. The trilobite fossils, found in tuffs containing zircon crystals, can be used to determine the age of the fossils and the eruption that formed the tuffs. This discovery not only helps date the fossils in Thailand but also provides insights into other parts of the world, such as China and Australia, where similar fossils have been found. The findings contribute to unraveling the complex puzzle of ancient geography and offer valuable information for understanding our planet's history.

Ancient Trilobites in Volcanic Rock Unravel Geography Mystery

Fossils of 490-million-year-old trilobites discovered in Thailand's Ko Tarutao region could provide insights into the ancient supercontinent of Gondwana. The fossils were found in a layer of volcanic rock called tuff, which contained zircon crystals that allowed researchers to date the eruption and the trilobites. The discovery of 10 new trilobite species and their correlation with other regions could shed light on the geological history of Gondwana. This finding may also help in dating similar fossils in other parts of the world and provide valuable information for understanding evolutionary change and extinctions.
