Trilobita Fossil Records from the Precordillera of San Juan and Mendoza, Argentina

1763 fossil specimens of the Trilobita class form this collection from the Precordillera of San Juan and Mendoza, Argentina. The specimens were collected and researched by Dr. Osvaldo Bordonaro and colleagues between 1994 and 2013. They are part of the Paleoinvertebrate Collection of the IANIGLA CCT CONICET Mendoza, curated by Lic. Susana Mariel Devincenzi.

Use Cases

• Classifying Trilobita specimens based on described taxonomic orders like Agnostida and Phacopida.
• Analyzing the stratigraphic distribution of fossils from described formations like La Laja and Alojamiento.
• Studying paleobiodiversity patterns in the Precordillera geological region of Argentina.
• Training models for fossil identification using specimen metadata likely present in the collection.

Strengths

• Contains 1763 individual fossil specimens, providing a substantial sample size.
• Specimens are associated with specific geological formations and time periods (e.g., Middle Cambrian).
• Collection is tied to a specific research institution (IANIGLA CCT CONICET Mendoza) and curator.
• Data collection spanned nearly two decades (1994-2013), suggesting longitudinal research effort.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific ML tasks.
• Last update date is unknown; freshness unverified.
