Early Permian discovery challenges Triassic Gondwana fossil classification.
Dicroidium, previously thought to be a key plant in Early Triassic Gondwana, has been found in well-preserved form in Early Permian rocks in India. This challenges the idea that Dicroidium is exclusive to the Triassic period and Gondwana region, suggesting it may have originated in a different area. The discovery raises questions about the use of Dicroidium as an index fossil for different periods in Gondwana's history.
