Haug et al. BMC Eutionary Biology , : http:biomedcentral-RESEARCH ARTICLEOpen AccessMorphology and function within the Cambrian Burgess Shale megacheiran arthropod Leanchoilia superlata and also the application of a descriptive matrixJoachim T Haug, Derek EG Briggs, and Carolin HaugAbstractBackground: Leanchoilia superlata is among the most effective known arthropods in the middle Cambrian Burgess Shale of British Columbia. Here we re-describe the morphology of L. superlata and talk about its probable autecology. The re-description follows a standardized scheme, the descriptive matrix strategy, developed to provide a template for descriptions of other megacheiran species. Results: Our findings differ in numerous respects from earlier interpretations. Examples include things like a far more slender body; a feasible hypostome; a little specialised second appendage, bringing the number of pairs of head appendages to four; a additional sub-division of your great appendage, producing it extra related to that of other megacheirans; along with a complex joint in the exopod reflecting the arthropod’s swimming capabilities. Conclusions: Various elements of your morphology, one example is, the morphology on the great appendage and also the presence of a basipod with get TM5275 (sodium) robust median armature on the biramous appendages indicate that L. superlata was an active and agile necto-benthic predator (not a scavenger or deposit feeder as previously interpreted).

It can be simpler to describe fossil species totally, but only simply because substantially less detail is offered. However, several descriptions of fossils are inadequate to allow them to become utilized straight to prepare cladistic matrices for phylogenetic analyses. This really is normally mainly because authors focus on morphological options that differentiate new species from those previously described.
