Amber is fossilized tree resin, and inclusions usually comprise terrestrial and, rarely, aquatic organisms. Marine fossils are extremely rare in Cretaceous and Cenozoic ambers. Here, we report a record of an ammonite with marine gastropods, intertidal isopods, and diverse terrestrial arthropods as syninclusions in mid-Cretaceous Burmese amber. We used X-ray–microcomputed...Yu, TingTing ; Kelly, Richard S ; Mu, Lin ; Ross, Andrew ; Kennedy, Jim …

Ancient fig wasps indicate at least 34 Myr of stasis in their mutualism with fig trees.
Fig wasps and fig trees are mutually dependent, with each of the 800 or so species of fig trees (Ficus, Moraceae) typically pollinated by a single species of fig wasp (Hymenoptera: Agaonidae). Molecular evidence suggests that the relationship existed over 65 Ma, during the Cretaceous. Here, we record the discovery...Compton, S G ; Ball, A D ; Collinson, M E ; Hayes, P ; Rasnitsyn, A P …
