| Summary: | The Palaeopascichnida are a relatively understudied component of the Ediacaran biota. The eponymous Palaeopascichnus delicatus is comprised of serially arranged, mm-scale allantoid chambers that have variously been interpreted as evidence of movement, feeding traces, and body fossils of various affinities. Palaeopascichnus has most recently been compared to the deep-marine Xenophyophora, an extant group of large benthic protists that is characterized by large size and possession of stercomata within their cells. The construction and growth of the palaeopascichnids, and its implications for their phylogenetic affinity, are assessed using material from the Avalon Peninsula of Newfoundland, Canada. The application of quantitative morphological analysis to the study of over ninety well-preserved specimens of Palaeopascichnus demonstrates considerable variation in chamber shape and size, and in behaviour along the chamber series. The combination of morphometric and multivariate statistical analysis allows the ... : Spreadsheet of all data_Hawco et al.All specimens, measurements, characters used in study and the full results of the cluster assignments.total_data_spreadsheet_Hawco et al..xlsxInterpretations of all cluster analyses_Hawco et al.Breakdown of how we interpreted the schematics for each cluster, as well as showing the averages for each character in each cluster for all iterationsInterpretations of cluster analyses_Hawco et al..xlsxSupplementary_information_Hawco_et_alSupplementary information file including results for the iteration where the branching palaeopascichnus specimens are treated separately, full table identifying the specimens used in the study, full hierarchical clustering trees for every iteration and the interpretations of schematics associated with the clusters.SI_PP_Hawco.docx ... |
