Morphometric and phylogeny data for: Morphology, variation, and systematics of the late Cambrian Laurentian dikelocephalid trilobite Walcottaspis vanhornei

These pages provide details of the taxa, characters and character states
used in the phylogenetic analyses of Walcottaspis vanhornei (Walcott,
1914) and relatives in the accompanying paper.  Phylogenetic
information included here provides details of characters and taxa used for
both the parsimony-based and Bayesian analyses and documents levels of
support of two types (Bremer and bootstrap) for the parsimony analysis.
Also included here is the result of Bayesian maximum likelihood analysis
that provides further support to the results of parsimony analysis. We
include bivariate plots of the variance explained by each relative warp
for the sclerites analyzed and morphometric measurement error analysis.
