Summary

This episode of ‘7 Days of Science’ presents a roundup of recent scientific news, focusing on paleontology but also covering other fields. The main story discusses a new study on Spinosaurus, suggesting it was not exclusively a fish-eater but also capable of hunting large land animals, based on tooth and jaw morphology comparisons with crocodilians. Other segments include: marmoset monkeys using names for each other, the first detection of Earth’s ambipolar electric field, an update on orcas interacting with yachts, a fossil of a prehistoric sea cow showing evidence of crocodile and shark attacks, the naming of two new dinosaur species (Coahuilasaurus lipani and Sasayamagnomus saegusai), a new prehistoric crocodyliform species, and a study on the shrinking size of cave lions before their extinction. Each story is presented with context and references to the underlying research.
