Actinopteria Bivalve Morphometric and Taphonomic Data from the Devonian Paraná Basin

Kevin William Richter provides a dataset supporting a systematic revision and taphonomic analysis of the pteriomorph bivalve genus Actinopteria from the Lower Devonian Ponta Grossa Formation in the Paraná Basin, Brazil. The data includes detailed shell morphometric parameters, taphonomic signatures, facies analysis, and ichnological data. It was last updated on 2026-05-19 and is shared under a CC-BY-4.0 license.

Use Cases

• Conducting systematic revisions of fossil bivalves based on morphometric parameters.
• Analyzing taphonomic signatures to infer transport history and depositional environments.
• Studying paleoecological adaptations, such as endobyssate modes of life, integrated with sedimentological evidence.

Strengths

• Includes data for a newly described species, Actinopteria grahni sp. nov.
• Dataset integrates multiple analysis types: morphometrics, taphonomy, facies, and ichnology.
• Explicitly expands the known morphological variability of Actinopteria langei.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (124.7 KB), indicating a limited scope of specimens or variables.
