Juvenile Anhanguerid Pterosaur Specimen from the Romualdo Formation, Brazil

A partial fossil specimen (MCT.R.1491) from the Aptian-Albian Romualdo Formation in Northeast Brazil. The dataset includes phylogenetic analysis and anatomical data for a medium-sized juvenile pterosaur with a 3.8–4.0m wingspan. It was authored by Anderson Nascimento and published on figshare under a CC-BY-4.0 license.

Use Cases

• Phylogenetic classification based on described anatomical features.
• Comparative anatomical studies of juvenile pterosaurs.
• Analysis of morphological variation within the Anhangueridae family.
• Investigating taphonomic conditions of fossils preserved in calcareous nodules.

Strengths

• Includes detailed anatomical description of a specific specimen (MCT.R.1491).
• Phylogenetic analysis supports taxonomic referral to Anhangueridae.
• Specifies a precise geological formation and time period (Romualdo Formation, Aptian-Albian).
• Notes a distinctive morphological feature (two large distal foramina on unguals).

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 very small (406.6 KB), indicating limited scope.
