CCATs Patrícia and Paulina show how global warming over the Pliensbachian-Toarcian boundary cooccurs with a shrinking of adult body size in two belemnite species, related to modern-day squid and cuttlefish. This supports the hypothesis that a decrease in body size is a common response to global warming in many organisms.
