Phylogenetic Character Matrix for Silurian Stem-Myriapod Fossils

A character matrix in TNT format based on Liu et al. [17] with additional taxa. The dataset was authored by Derek Briggs and last updated on April 13, 2026. It is licensed under CC-BY-4.0 and hosted on figshare.

Use Cases

• Conducting phylogenetic analysis based on the character matrix format.
• Testing evolutionary hypotheses about terrestrialization based on the described fossil traits.
• Comparing morphological characters across additional taxa included in the matrix.
• Replicating or extending the cladistic methodology from the cited reference.

Strengths

• Derived from a published reference (Liu et al. [17]), providing a methodological foundation.
• Includes additional taxa beyond the original source, potentially expanding taxonomic coverage.
• Uses the TNT format, a standard for phylogenetic analysis software.

Limitations

• Row and column counts are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
