Thuy et al. report two temporally consecutive species of fossil brittle stars and reveal a process of miniaturization during a Silurian environmental crisis. This study sheds light on the evolution of the modern brittle star body plan and provides in

Elasmosaurid plesiosaurians were globally prolific marine reptiles that dominated the Mesozoic seas for over 70 million years. Their iconic body-plan incorporated an exceedingly long neck and small skull equipped with prominent intermeshing 'fangs'.

BACKGROUND: During their evolution in the Late Cretaceous, mosasauroids attained a worldwide distribution, accompanied by a marked increase in body size and open ocean adaptations. This transition from land-dwellers to highly marine-adapted forms is
