    The Controversy Over a Second Species of Giant Anaconda

    The Green Anaconda, Eunectes murinus, has long been Amazonia’s most iconic animal. It is widely regarded as the largest snake in existence. However, in a groundbreaking development, Rivas et al. published a paper in February 2024, unveiling a second species of giant anaconda, Eunectes akajima. This discovery, while not entirely unexpected due to the cryptic nature…

  • Booids from the early-middle Eocene of Messel (Germany) and infra-red pits

    Well preserved fossil booids from Messel Germany Abstract. Our knowledge of the early evolution of snakes is improving, but all that we can infer about the evolution of modern clades of snakes, such as boas (Booidea), is still based on isolated bones. Here, we resolve the phylogenetic relationships of Eoconstrictor fischeri comb. nov. and other…
