Abstract Thryptodus zitteli Loomis (Actinopterygii: Tselfatiiformes) is an enigmatic Late Cretaceous bony fish with a massive blunt rostrum that lived in the Western Interior Seaway of North America. Here, a second species of Thryptodus , T. loomisi sp. nov., is described on the basis of two skulls and some isolated rostra from the Britton Formation (Cenomanian–lower Turonian) of Texas, USA. In addition, the type species, T. zitteli , is redescribed and a nearly complete skeleton of the species ...

Abstract Numerous individuals of a ghost shrimp, here described as a new species, Mesostylus pervesleri , are recorded from the lower Maastrichtian Piesting Formation at Muthmannsdorf in Lower Austria. The accompanying molluscan fauna comprises bivalves, gastropods and cephalopods that are indicative of a low-energy, shallow-marine environment with normal salinity. The ghost shrimp body fossils are associated with two types of trace fossil; one of these is here interpreted as the remains of a ca...

Abstract A new family Yetkhatidae Song, Szwedo et Bourgoin fam. nov. from mid-Cretaceous amber of Myanmar is described. It is characterized by the tegmina with a triangular basal cell and in having the apex of the clavus closed, the female genitalia with robust endogonocoxal processes, the head capsule with trigones and foliated frontal margins, ridged lora (visible frontally) and by intermediate carinae on the mesonotum. Two new monotypic genera are described in this new family: Yetkhata Song, ...

Abstract A new fossil burmaeshnid, Proaeschna zhangi gen. et sp. nov., is described from the mid-Cretaceous Burmese amber. Its well-preserved wing base structure allows us to illustrate the morphological details of wing base in the fossil Odonata for the first time. The proximal costal plate in the new species consists of the anterior and posterior parts which are fused together with a suture. The anterior proximal costal plate in P. zhangi and extant Odonata is homologized to the basalare of Pr...
