Metamorphosis is a striking feature in the development of an animal. For arthropods, metamorphosis is usually understood as a rapid morphological change, which occurs within one or two moults. We describe here two conspecific fossil larvae of an achelatan lobster from the Solnhofen Lithographic Limestones (Upper Jurassic, southern Germany). These phyllosoma-like larvae represent successive instars. Both have a combination of characters specific for phyllosoma larvae and those typical for post-phyllosoma instars. This find indicates that the developmental pattern of this achelatan species was more gradual or "less metamorphic" than in all other achelatans known, and probably represents the plesiomorphic condition. Obviously, heterochrony played an important role in the evolution of metamorphosis in Achelata. Developmental data from other fossil arthropods, e.g., stomatopod crustaceans or pterygote insects, also point to a more gradual ontogenetic pattern in the ancestors of these lineages, which show a "real" metamorphosis today. The evolution of metamorphosis is linked to selective pressure on early developmental stages, resulting in morphological disparity between pre-and post-metamorphic stages, and a condensation of the ontogenetic pattern, leading to a more rapid morphological change. The influence of both factors can be better evaluated if fossil information is taken into account.• Key words: metamorphosis, Palaeo-Evo-Devo, larval biology, Decapoda, Eucrustacea. Greifswald, Soldmannstraße 23, 17487 Greifswald, Germany; joachim.haug@palaeo-evo-devo.info, joachim.haug@uni-greifswald.de Metamorphosis describes a rapid change of the morphology during ontogeny. What this exactly means, or more exactly to which ontogenetic sequences the term metamorphosis should be applied, differs from author to author (see discussion in Williamson 1982). The differences in applying the term metamorphosis concern both the amount and the rapidness of change. The amount of change means the differences in morphology between the last developmental stage before and the first stage after metamorphosis, while the rapidness of change refers to how fast this entire process happens. Yet, there are some cases in which it is easier to decide than in others, whether a developmental change is a metamorphosis or not. Among arthropods usually those taxa are considered to undergo metamorphosis, which change their morphology drastically within a single or at most two moults, with this characterizing the degree of rapidness of this change. Practically, this means that the animal creeping out of the old cuticle shows only little resemblance to its old "skin".A well-known example are holometabolous insects. Here the larva, for example, a caterpillar, moults into the pupa (in fact another type of larva; see Barnes et al. 1993), which moults into the adult, in this case a butterfly. While holometabolous insects are probably the best-known example for metamorphosis within arthropods, also among crustaceans drastic changes of morphology within no m...

“…In the Carboniferous numerous sites have yielded stomatopod fossils, e.g., the deposits of Mazon Creek and Bear Gulch, both North America, Hagen-Vorhalle in Germany, East Kilbride in Scotland, and Argenteau in Belgium. Fourteen species are currently recognized from this period, representing various evolutionary levels (e.g., Peach, 1908;van Straelen, 1922;Schöllmann, 2004;Schram, 2007Schram, , 2010Haug J.T. et al, 2010).…”

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 calcium phosphate. The dactyli have an estimated maximum length of 15 millimeters and bear six spines. The specimens appear to be hollow and preserve fine details, especially a narrow crest on the dorsal side of the spines, a functional blade edge that has not been previously found on any fossil stomatopod. The specimens are provisionally attributed to the species Squilla empusa, found nowadays along the entire East coast of the United States of America. Fossil occurrences are known from the Pleistocene of Maryland and from the late Pleistocene or early Holocene of Connecticut. Though isolated dactyli are less informative on the taxonomic level, they can be important on the paleo-ecological level, positively demonstrating the presence of ambush predators in an investigated paleo-community. Given the scarce stomatopod fossil record and the exceptional three-dimensional preservation, the finding of these specimens, despite their fragmentary nature, is regarded as significant.Keywords: Squilla empusa, three-dimensional preservation, imaging, phosphatized fossils, paleoecology, predators.

Ecologically Driven Ultrastructural and Hydrodynamic Designs in Stomatopod Cuticles

Ecological pressures and varied feeding behaviors in a multitude of organisms have necessitated the drive for adaptation. One such change is seen in the feeding appendages of stomatopods, a group of highly predatory marine crustaceans. Stomatopods include "spearers," who ambush and snare soft bodied prey, and "smashers," who bludgeon hard-shelled prey with a heavily mineralized club. The regional substructural complexity of the stomatopod dactyl club from the smashing predator Odontodactylus scyllarus represents a model system in the study of impact tolerant biominerals. The club consists of a highly mineralized impact region, a characteristic Bouligand architecture (common to arthropods), and a unique section of the club, the striated region, composed of highly aligned sheets of mineralized fibers. Detailed ultrastructural investigations of the striated region within O. scyllarus and a related species of spearing stomatopod, Lysiosquillina maculate show consistent organization of mineral and organic, but distinct differences in macro-scale architecture. Evidence is provided for the function and substructural exaptation of the striated region, which facilitated redeployment of a raptorial feeding appendage as a biological hammer. Moreover, given the need to accelerate underwater and "grab" or "smash" their prey, the spearer and smasher appendages are specifically designed with a significantly reduced drag force.
