Bonapartenykus ultimus Anatomical Data with Phylogenetic and Disparity Analyses

J. G. Meso published a 5.0 MB dataset on figshare in 2026, providing an anatomical redescription of the Late Cretaceous dinosaur Bonapartenykus ultimus. The dataset includes 3D reconstructions, phylogenetic assessments, and disparity analyses comparing Patagonykinae and Parvicursorinae alvarezsaurids. It is licensed under CC-BY-4.0.

Use Cases

• Conduct phylogenetic placement based on the updated phylogenetic assessment and diagnosis.
• Analyze morphological disparity between dinosaur clades based on the disparity metrics mentioned.
• Study anatomical features and autapomorphies based on the detailed 3D reconstructions.
• Model evolutionary trajectories and selective pressures using the phylogenetic generalised least-squares (pGLS) analysis.

Strengths

• Includes multiple file formats (NEX, R, RUN, XLSX, DOCX, TXT) for different analytical workflows.
• Dataset is 5.0 MB, facilitating relatively quick download and inspection.
• License is CC-BY-4.0, permitting broad reuse with attribution.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Based on a single fragmentary specimen, which may limit statistical power for some analyses.
