Abstract A review and revision of the Paleozoic proto-stomatopods results in the recognition of a new species of Tyrannophontes Schram, 1969, T. gigantion, from the Middle Pennsylvanian Mazon Creek, Essex biota. A new family, Daidalidae, and new genus, Daidal, are required to separate a previously recognized taxon, T. acanthocercus Jenner, Hof, and Schram, 1998. Both Perimecturus pattoni Peach, 1908 and Gorgonophontes cf. fraiponti (Schöllmann, 2004) appear at present to be best placed within… 

Evolution of mantis shrimps (Stomatopoda, Malacostraca) in the light of new Mesozoic fossils

These new data are used to reconsider the phylogeny of Stomatopoda and demonstrate the importance of these fossils for understanding mantis shrimp evolution and the interpretation of evolutionary pathways of particular features.

Isolated mantis shrimp dactyli from the Pliocene of North Carolina and their bearing on the history of Stomatopoda

We describe 54 fragmentary specimens from the Pliocene of North Carolina that represent isolated dactyli of mantis shrimps. These specimens are preserved uncompressed within three dimensions in

A new fossil mantis shrimp and the convergent evolution of a lobster-like morphotype

Mesozoic eumalacostracans represent an important ‘experimental set-up’ for research on factors leading to convergent evolution, the understanding of which is still one of the puzzling challenges of modern evolutionary theory.

Mitogenomics and the Phylogeny of Mantis Shrimps (Crustacea: Stomatopoda)

An ancestral state reconstruction was performed on the raptorial claw form and provides support that spearing is the ancestral state for extant Stomatopoda, with smashing evolving subsequently one or more times.

Stomatopod Interrelationships: Preliminary Results Based on Analysis of three Molecular Loci

Molecular analyses suggest the novel possibility that Hemisquillids and possibly Pseudosquillidae, rather than being basal or near basal in Gonodactyloidea, may be basal overall to the extant stomatopods.

The evolutionary history of Stomatopoda (Crustacea: Malacostraca) inferred from molecular data

Ancestral state reconstructions revealed that the most recent common ancestor of extant stomatopods had eyes with six midband rows of hexagonal ommatidia, and this is consistent with the malacostracan ground-plan.

Functional morphology, ontogeny and evolution of mantis shrimp‐like predators in the Cambrian

The arrangement of the elbow joint supports the view that the great appendage evolved into the chelicera of Chelicerata sensu stricto, as similar joints are found in various ingroup taxa such as Xiphosura, Opiliones or Palpigradi.

On the Origin of Decapoda

Molecular phylogenetic trees for the closely related families Callianassidae and Ctenochelidae as well as for outgroup representatives of the family Axiidae are generated and support was found for continued recognition of many separate genera in this group and for the naming of additional ones.

The importance of lithographic limestones for revealing ontogenies in fossil crustaceans

A summary of the occurrences of crustacean fossils providing developmental information and a demonstration of the potential of the lithographic limestones in this context are presented.

The situation seems hopeless, although new data, new lines of evidence, and new perspectives might provide better insight some time in the future.



The phylogeny of the stomatopod Crustacea

The present analysis suggests that the Unipeltata diverged in two broad directions from the outset, so the gonodactyloid ‘smashers’ became specialised for hard substrates, and the remainder diversified into the other modern superfamilies, evolving more efficient ‘spearing’ claws, and occupying soft substrates.

Palaeo- and archaeostomatopods (Hoplocarida, Crustacea) from the Bear Gulch Limestone, Mississippian (Namurian), of central Montana

A cladistic phylogenetic analysis of the Hoplocarida including the Paleozoic forms resolves the higher level relationships of the hoplocarids and reveals some newly recognized characters of those taxa and suggests some novel interpretations of hop Locarid evolution.

Phylogenetic Analysis of the Stomatopoda (Malacostraca)

A cladistic analysis of all 20 families of the Unipeltata, rooted with four fossil outgroups, resulted in a single, fully resolved topology that largely support the existing five-superfamily classification.

Fossil stomatopods (Crustacea: Malacostraca) and their phylogenetic impact

The Stomatopoda form a distinctive order within the Malacostraca, an ancient group of benthic, obligate carnivorous crustaceans, which seems well established; their phylogeny, however, still remains unclear.


The present volume relating to Crustacea and Echinodermata collected by Mr. Vanderbilt is full of interesting material, and among the Caridea there are many new species.

Prothelyphonus naufragus n.sp., ein neuer Geisselskorpion (Arachnida: Thelyphonida: Thelyphonidae) aus dem Namurium (unteres Ober-Karbon) von West-Deutschland

A thelyphonid specimen from the Vorhalle beds (Namurian B ; R2c subzone of the goniatite stratigraphy) of the Ruhr area of West Germany is figured and described, which presents the oldest known species of this ordo of Arachnida.

Hagen-Vorhalle, a new important Namurian insecta-bearing locality (Upper Carboniferous; FR Germany

A new important Upper Carboniferous Insecta-bearing locality has been discovered near Hagen-Vorhalle (Ruhr area, FR Germany) which has yielded about 60 specimens, most of them being nearly completely

Miscellaneous late Paleozoic Malacostraca of the Soviet Union

Various Late Paleozoic malacostracan Crustacea from the Soviet Union are reviewed and an undescribed Late Devonian caridoid eumalacostrastracan is discussed.
