BackgroundThylacocephala is a group of enigmatic extinct arthropods. Here we provide a full description of the oldest unequivocal thylacocephalan, a new genus and species Thylacares brandonensis, which is present in the Silurian Waukesha fauna from Wisconsin, USA. We also present details of younger, Jurassic specimens, from the Solnhofen lithographic limestones, which are crucial to our interpretation of the systematic position of Thylacocephala. In the past, Thylacocephala has been interpreted… 
A new thylacocephalan crustacean from the Upper Jurassic lithographic limestones of southern Germany and the diversity of Thylacocephala
A new genus and species of thylacocephalan crustaceans are described from the Upper Jurassic Solnhofen limestones of Eichstatt (Altmuhltal Formation), Falcatacaris bastelbergeri n.
First African thylacocephalans from the Famennian of Morocco and their role in Late Devonian food webs
Sedimentary facies and faunal composition of the Thylacocephalan Layer suggest that these animals populated the water column above the low-oxygen sea floor, and thylacocephalans likely represented an important component of the diet of chondrichthyans and placoderms, which are quite common as well.
Upper Ordovician Thylacocephala (Euarthropoda, Eucrustacea) from Bohemia indicate early ecological differentiation
Even though the newly described taxa represent the oldest unequivocal thylacocephalans, their carapaces display several characters most similar to those of Mesozoic groups, whether these similarities reflect true close relationships and Ordovician origins for these groups or are only the result of convergent evolution is uncertain.
Morphology and anatomy of the Late Jurassic Mayrocaris bucculata (Eucrustacea?, Thylacocephala) with comments on the tagmosis of Thylacocephala
It is demonstrated that the raptorial appendages of Thylacocephala are most probably maxillulae, maxillae and maxillipeds, and new details on the posterior trunk appendages are reported, including the description of a paddle-like proximal part and of a rod-like distal part, but also of a specialized terminal trunk appendage.
First Carboniferous thylacocephalan from Europe and its significance for the understanding of functional morphology of Concavicarididae Schram, 2014
This paper describes the first thylacocephalan known from the Carboniferous (Mississippian) of Europe, Concavicaris viktoryni sp.
Bivalved arthropods from the Middle Ordovician Winneshiek Lagerstätte, Iowa, USA
Abstract. The Middle Ordovician (Darriwilian) Winneshiek Lagerstätte of northeast Iowa is preserved in a meteorite crater. Besides conodonts, the fossils are dominated by arthropods, particularly
After 100 years: a detailed view of an eumalacostracan crustacean from the Upper Jurassic Solnhofen Lagerstätte with raptorial appendages unique to Euarthropoda
The Solnhofen Konservat‐Lagerstätte yields a great number of remarkably preserved fossils of eumalacostracan crustaceans that help us understand the early radiation of several groups with modern
New Thylacocephala (Crustacea) assemblage from the Spathian (Lower Triassic) of Majiashan (Chaohu, Anhui Province, South China)
A new assemblage of Thylacocephala (Crustacea) from the late Spathian (Early Triassic) of Chaohu, Anhui Province, South China is reported and described, suggesting they might have constituted a food source for the fishes and marine reptiles in the chaohu Fauna.
New thylacocephalans from the Cretaceous Lagerstätten of Lebanon
This study focuses on new thylacocephalans from the Late Cretaceous Konservat-Lagerstatten of Lebanon, which yielded the youngest representatives of the group and links the Thylacocephala to the Crustacea.


Thylacocephala (Arthropoda: Crustacea?) from the Cretaceous of Lebanon and implications for thylacocephalan systematics
An intensive study of a collection of arthropods from the Cretaceous of Lebanon reveals that these forms belong to the problematical arthropod class Thylacocephala, and unique characters of at least the genus Protozoea are the numerous ‘pits’ covering the entire carapace, elongated anterior rostral and posterior spines, and a dorsal hinge indicative of a truly bivalved carapaces.
Form and function in Thylacocephala, Conchyliocarida and Concavicarida (?Crustacea): a problem of interpretation
It is suggested that at least some thylacocephalans were mesopelagic predators, and may have attained neutral buoyancy from their food substrate of shark and coleoids.
The Early Cambrian origin of thylacocephalan arthropods
Zhenghecaris shankouensis gen. et sp. nov. is one of the largest “bivalved” arthropods of the Lower Cambrian Maotianshan Shale fauna. Its non−mineralized carapace was dome−like, laterally compressed,
Family level classification within Thylacocephala, with comments on their evolution and possible relationships
This work proposes a redefinition of the two orders, and recognition of seven families, five of them new, of thylacocephala, a distinct class composed of two orders composed of Concavicarida and Conchyliocarida.
A new exceptionally preserved biota from the Lower Silurian of Wisconsin, U.S.A.
A new biota including lightly sclerotized and soft-bodied organisms occurs in finely laminated argillaceous dolomites of late Llandoverian age in Waukesha County, Wisconsin. This discovery fills a
Abstract The morphology of Tuzoia is reinterpreted in the light of abundant new specimens from the Middle Cambrian Burgess Shale (British Columbia, Canada) and Kaili (Guizhou, China) Lagerstätten.
First fossil stomatopod larva ( Arthropoda : Crustacea ) and a new way of documenting Solnhofen fossils ( Upper Jurassic , Southern Germany )
We report the first undisputable fossil larval stomatopod, as previous records all refer to thylacocephalans. The single specimen has been found in the Upper Jurassic Solnhofen Lithographic
Cambrian ‘Orsten’-type arthropods and the phylogeny of Crustacea
‘Orsten’ is a special type of anthraconitic, organic-rich, concretionary limestone which is intercalated in the Upper Cambrian Alum Shale of southern Sweden and is extended to embrace a type of lagerstatten with a particular type of fossil preservation, i.e. the three-dimensional preservation of phosphatized cuticle-bearing organisms.
This is the earliest known unequivocal synziphosurine, extending their fossil record from the Wenlock to the Llandovery, and only the second species to be described with prosomal appendages; the presence of six pairs contrasts with the seven in the synziphateine Weinbergina opitzi, but is comparable to the number in modern horseshoe crabs.
Taphonomy of Exceptionally Preserved Crustaceans from the Upper Carboniferous of Southeastern Ireland
Abstract The Castlecomer Fauna, a Konservat-Lagerstätte from the Upper Carboniferous of Ireland, is dominated by two species of exceptionally preserved spinicaudatan conchostracan branchiopod
