Long-term stasis in a diverse fauna of Early Cretaceous springtails (Collembola: Symphypleona)
Springtails (Hexapoda: Entognatha: Collembola) extend into at least the Early Devonian, but have a meagre record as fossils until the latter part of the Mesozoic. Here, we document a diverse fauna ofExpand
The semi-aquatic pondweed bugs of a Cretaceous swamp
Pondweed bugs (Hemiptera: Mesoveliidae), considered a sister group to all other Gerromorpha, are exceedingly rare as fossils. Therefore, each new discovery of a fossil mesoveliid is of high interest,Expand
General Palaeontology, Systematics and Evolution (Invertebrate Palaeontology) The oldest known riffle beetle (Coleoptera: Elmidae) from Early Cretaceous Spanish amber
Abstract Elmadulescens rugosus Peris, Maier et Sanchez-Garcia n. gen. n. sp. is described based on a single specimen from Spanish amber (El Soplao outcrop, Early Albian, Early Cretaceous). TheExpand
A rich and diverse tanaidomorphan (Crustacea: Tanaidacea) assemblage associated with Early Cretaceous resin-producing forests in North Iberia: palaeobiological implications
The extinct tanaidomorphan diversity from Early Cretaceous Spanish amber, currently comprising 26 specimens, is reassessed. The fossil family Alavatanaidae Vonk & Schram, 2007, described from SpanishExpand
Springtails from the Early Cretaceous Amber of Spain (Collembola: Entomobryomorpha), with an Annotated Checklist of Fossil Collembola
ABSTRACT Entomobryomorphan springtails (Hexapoda: Entognatha: Collembola) of the family Isotomidae are the most numerous group of Collembola in Spanish amber, a pattern typical in other studiedExpand
The first water measurers from the Lower Cretaceous amber of Spain (Heteroptera, Hydrometridae, Heterocleptinae)
Abstract Two fossils belonging to a new genus and species of water measurer (Gerromorpha, Hydrometridae), Alavametra popovi Sanchez-Garcia and Nel gen. n., sp. n., are described as first definitiveExpand
New species of fossil oribatid mites (Acariformes, Oribatida), from the Lower Cretaceous amber of Spain
Abstract Mites are relatively common and diverse in fossiliferous ambers, but remain essentially unstudied. Here, we report on five new oribatid fossil species from Lower Cretaceous Spanish amber,Expand
Mating and aggregative behaviors among basal hexapods in the Early Cretaceous
Among the many challenges in paleobiology is the inference and reconstruction of behaviors that rarely, if ever, leave a physical trace on the environment that is suitable for fossilization. OfExpand
Palaeobiology of tanaidaceans (Crustacea: Peracarida) from Cretaceous ambers: extending the scarce fossil record of a diverse peracarid group
Diverse assemblages of tanaidacean peracarid crustaceans from western Tethyan continental deposits suggest that the group was relatively common in or around ancient resin-producing forests. Here weExpand
Diverse assemblages of tanaids (Crustacea) related to Albian-Cenomanian resin-producing forests in Western Europe and their paleobiological implications
Attempts at reconstructing amber forest habitats have sometimes neglected some aspects concerning arthropod communities in the soil, particularly those related to humid terrestrial conditions with,Expand
