This paper on the Araripe orthopterofauna reviews the Cearagryllus-like Grylloidea (Orthoptera: Ensifera) from the laminated limestone of the uppermost part of the Crato Member, lowest unit of the Santana Formation (Early Cretaceous), Araripe Basin, near Santana do Cariri and Nova Olinda municipalities (Ceará State, Northeast Brazil). The following new taxa are proposed: Notocearagryllus arturandradai n. sp., Cryptocearagryllus revelatus n. gen. et n. comb., Allocearagryllus leipnitzi n. gen et n. comb., Cearagrylloides perforatorius n. gen. et n. comb., Cearagrylloides microcephalus n. gen. et n. comb., Cearagrylloides previstus n. gen. et n. comb., and Paracearagryllus poliacanthus n. gen. et n. comb. (Cearagryllinae n. subfam.). Additionally new data on the paleoecology and paleoethology are furnished as well as a statistical approach.

Here we describe three fossil feathers from the Early Cretaceous Santana Formation of the Araripe Basin, Brazil. Feathers are the most complex multiform vertebrate integuments; they perform different functions, occurring in both avian and non-avian dinosaurs. Despite their rarity, fossil feathers have been found across the world. Most of the Brazilian feather fossil record comes from the Santana Formation. This formation is composed of two members: Crato (lake) and Romualdo (lagoon); both of which are predominantly reduced deposits, precluding bottom dwelling organisms, resulting in exceptional preservation of the fossils. Despite arid and hot conditions during the Cretaceous, life teemed in the adjacency of this paleolake. Feathered non-avian dinosaurs have not yet been described from the Crato Member, even though there are suggestions of their presence in nearby basins. Our description of the three feathers from the Crato laminated limestone reveals that, despite the small sample size, they can be referred to coelurosaurian theropods. Moreover, based on comparisons with extant feather morphotypes they can be identified as one contour feather and two downy feathers. Despite their rareness and low taxonomic potential, fossilized feathers can offer insights about the paleobiology of its owners and the paleoecology of the Araripe Basin.

AbstractA specimen of the Early Cretaceous amiiform fish Calamopleurus cylindricus with stomach content is described from the Santana Formation, Brazil. The prey concerns a smaller conspecific individual. Until now, prey items documented for Calamopleurus almost exclusively involved the aspidorhynchid Vinctifer. On the basis of the present record it is suggested that the prey preference of Calamopleurus was less pronounced than previously assumed.

Proprionoglarisguyoti gen. nov., sp. nov., Parapsyllipsocus vergereaui gen. nov., sp. nov., and Prospeleketoralbianensis gen. nov., sp. nov. are described from the Early Cretaceous amber of Archingeay (SW France). Libanoglarismouawadi gen. nov., sp. nov. is described from the Early Cretaceous amber of Lebanon. They are all placed into the suborder Trogiomorpha, incertae familiae. The discovery of these new taxa together with a first phylogenetic analysis of the trogiomorphan families demonstrate the necessity of a cladistic redefinition of the currently admitted major subdivisions of this suborder.

ABSTRACTDermaptera (earwigs) are described from the Triassic of Australia and England, and from the Jurassic and Cretaceous of England. Phanerogramma heeri (Giebel) is transferred from Coleoptera and it and Brevicula gradus Whalley are re-described. Seven new taxa are named based on tegmina: Phanerogramma australis sp. nov. and P. dunstani sp. nov. from the Late Triassic of Australia; P. gouldsbroughi sp. nov. from the Triassic/Jurassic of England; Brevicula maculata sp. nov. and Trivenapteron moorei gen. et sp. nov. from the Early Jurassic of England; and Dimapteron corami gen et sp. nov. and Valdopteron woodi gen. et sp. nov. from the Early Cretaceous of England. Phanerogramma, Dimapteron and Valdopteron are tentatively placed in the family Dermapteridae, and Trivenapteron is incertae sedis. Most of the specimens of Phanerogramma heeri are from the Brodie Collection and labelled ‘Lower Lias'; however, some were collected from the underlying Penarth Group, thus this species spans the Triassic/Jurassic boundary. The palaeobiogeography of the Late Triassic and Early Jurassic of England is discussed.
