Summary
[edit]DescriptionDiorama of a Silurian seafloor - eurypterid 2 (31834971848).jpg |
Seen here is a model-based reconstruction of life on an ancient seafloor during the Silurian. This is a public exhibit at Carnegie Museum of Natural History in Pittsburgh, Pennsylvania. The eurypterids, or sea scorpions, are an extinct group of chelicerate arthropods. They have an elongated, scorpion-like body that could reach enormous sizes (2.5 to 3 meters!), with a nonmineralizing exoskeleton composed of chitinous material. They are generally found in shallow to very shallow water marine and marginal marine facies. Classification: Animalia, Arthropoda, Chelicerata, Merostomata, Xiphosura, Eurypterida, Eurypteridae |
