A 500-million-year-old fossil called Mollisonia symmetrica suggests that spiders and scorpions may have originated from marine ancestors rather than land-dwelling ones, challenging previous beliefs about arachnid evolution and indicating a deep oceanic connection.
A fossil of Mollisonia symmetrica, an ancient arthropod, reveals a backward brain similar to modern spiders, suggesting that spider ancestors may have evolved in the ocean rather than on land, challenging previous beliefs about arachnid origins.
A 500-million-year-old fossil of Mollisonia suggests that the brains of spiders and related arachnids may have evolved in the oceans before transitioning to land, challenging traditional views on their terrestrial origins and indicating a marine ancestry for these creatures.
Scientists in Australia have discovered the largest fossilized spider ever found on the continent, belonging to a new species called Megamonodontium mccluskyi, which lived 11-16 million years ago during the Miocene epoch. The well-preserved fossil reveals insights into ancient rainforest ecosystems and arachnid evolution, suggesting that similar environments once covered Australia before aridification led to the extinction of such species.
