Cladistic revision of Cretaceous Brachylepadomorpha and Verrucomorpha dataset

Abstract

This dataset supports the publication by Andy S. Gale & S U. Vidovic "The origins of major sessile cirripede groups; a revision of Cretaceous Brachylepadomorpha and Verrucomorpha" in Journal of Systematic Palaeontology DOI: 10.1080/14772019.2023.2258370 This dataset comprises the TNT script to run a cladistic analysis of sessile cirripede groups and bootstrap resampling with 1000 replicates; the output files from TNT; the supporting Nexus file; and an R script for post-analysis of the tree to calculate the Gap Excess Ratio (GER). The cladistic analysis comprises 48 characters, one of which is continuous, all others were treated as unordered with equal weights. The TNT script also contains instructions to run an implied weights analysis. To successfully execute the TNT script, the user will need to include the correct file path to their own copy of Stats.run, a TNT script for calculating the ensemble consistency index and retention index. TNT scripts can be given a .tnt extension and can be read by TNT and Mesquite. Nexus files can be given a .nex extension and can be read by Mesquite and TNT. R files can be given a .r extension and can be run in RStudio. The output log can be read in plain text, .tre and .nex output files can be opened by all the software used in this study. Contributions to this dataset: Gale made intellectual contributions with respect to the anatomy, systematics and stratigraphic occurrence of sessile cirripede groups. Gale: co-designed the analysis; wrote the characters; coded the matrix. Vidovic made intellectual contributions with respect to cladistic analysis and post-analysis. Vidovic: wrote the dataset; co-designed and executed the analysis; wrote the scripts and functions; created the files; edited the characters; coded the matrix.
