Summary

The Paleozoic Era was home to many strange and fascinating extinct groups, and among the most eye-catching of these were the eurypterids. Colloquially called “sea scorpions,” these carnivorous aquatic arthropods came in many forms for many habitats and are now known from many amazing fossils. In this episode, we discuss what makes eurypterids distinct from similar organisms, what we know about their lifestyles, and the many ways they continue to surprise and confuse us. In the news: Brazilian crocs, injured cats, breeding ichthyosaurs, and mammal-munching dinos.
