Anatomical character matrix of early ornithischian dinosaurs

Anatomical character matrix for the project "Taxonomic,
palaeobiological and evolutionary implications of a new phylogenetic
hypothesis for Ornithischia (Archosauria: Dinosauria)" - this dataset
contains revised/updated anatomical character scores for most early
(Middle Triassic - Early Jurassic) dinosauriforms and expands
upon a number of previous studies in terms fo sampling.
It contains a broader sample of early ornithischian dinosaur taxa
then previous studies, for example the early thyreophroan Scelidosaurus
harrisonii, the early neornithischians Hexinlusaurus
multidens and Agilisaurus louderbacki, and the
'primitve' ornithischian Laquintasaura
venezualae have all been added. The enigmatic and probleamtic
taxon Chilesaurus diegosaurezi is also included
in the dataset.  The dataset now reresents the most up
to date version of a working anatomical dataset of early dinosaurs and
close dinosaur relatives, which has been designed primarily to analyse the
interaltionships between the major dinosauriform groups. The taxa
contained in the dataset were scored for 282 anatomical characters,
producing a matrix that can be analysed using a number of different
methods. The following anatomical characters are to be considered
as additive characters: 4, 13, 18, 25, 63, 82, 84, 87, 89, 109, 142, 166,
174, 175, 184, 186, 190, 201, 203, 205, 209, 212, 225, 235, 236, 239, 250
and 256.
