Cretaceous amber inclusions illuminate the evolutionary origin of tardigrades

Supplementary files to the \"Cretaceous amber inclusions illuminate the evolutionary origin of tardigrades\" paper which include All raw files from the phylogenetic analysis (i.e., t, p, and tree files fromMrBayes, output tree from ASTRAL and IQTree, mcmc files from MCMCTree, and tre and log files from BEAST), RScripts used, and assembled Actinarctus doryphorus genome.
Tardigrades are a diverse phylum of microscopic invertebrates widely known for their extreme survival capabilities. Molecular clocks suggest that tardigrades diverged from other panarthropods before the Cambrian, but their fossil record is extremely sparse. Only the fossil tardigrades Milnesium swolenskyi (Late Cretaceous) and Paradoryphoribius chronocaribbeus (Miocene) have resolved taxonomic positions, restricting the availability of calibration points for estimating for the origin of this phylum. Here, we revise two crown-group tardigrades from Canadian Cretaceous-aged amber using confocal fluorescence microscopy, reveal..., , , # Data from: Cretaceous amber inclusions illuminate the evolutionary origin of tardigrades
