Abstract
En 中文
• • Opalized echinoderms reveal an exceptional Early Cretaceous Gondwana fauna. • • Articulated isocrinids document complex stalked crinoids in lagoonal settings. • • Jenoaster gen. nov. extends the record of zoroasterids into the Early Cretaceous. • • Rapid obrution was the primary mechanism of exceptional fossil preservation. • • Australian opals deposits constitute high-fidelity Cretaceous lagerstätten.
